    here is what i had on who is cautioning about what with relations to cwd tse prion and zoonosis potential, or has it already happened as sporadic cjd, i have put all recent science on cwd tse prion zoonosis from prion conference 2015, 2016, and 2017 in the Mississippi Health report link, and there was a recent article with a map of the GL area that might help ;

    Surveillance for the disease is ongoing, and DNR added a new nine-township Core CWD Area in Montcalm and Kent counties in late 2017.

    [​IMG]

    Also, the confirmation of CWD in a free-ranging deer from Montcalm County last September led to the mandatory testing of heads for all deer harvested by hunters within 72 hours and within 5 miles of the core area.

    “We continue to test deer from portions of Montcalm and Ionia counties that were harvested during the special January deer season,” Niewoonder said. “There are at least 34 deer from Montcalm County that are either confirmed or suspected CWD-positive from this past deer season.”

    ZOONOTIC CHRONIC WASTING DISEASE CWD TSE PRION UPDATE ???

    here is the latest;

    Cervid to human prion transmission

    Kong, Qingzhong

    Case Western Reserve University, Cleveland, OH, United States

    Abstract

    Prion disease is transmissible and invariably fatal. Chronic wasting disease (CWD) is the prion disease affecting deer, elk and moose, and it is a widespread and expanding epidemic affecting 22 US States and 2 Canadian provinces so far. CWD poses the most serious zoonotic prion transmission risks in North America because of huge venison consumption (>6 million deer/elk hunted and consumed annually in the USA alone), significant prion infectivity in muscles and other tissues/fluids from CWD-affected cervids, and usually high levels of individual exposure to CWD resulting from consumption of the affected animal among often just family and friends. However, we still do not know whether CWD prions can infect humans in the brain or peripheral tissues or whether clinical/asymptomatic CWD zoonosis has already occurred, and we have no essays to reliably detect CWD infection in humans. We hypothesize that:

    (1) The classic CWD prion strain can infect humans at low levels in the brain and peripheral lymphoid tissues;

    (2) The cervid-to-human transmission barrier is dependent on the cervid prion strain and influenced by the host (human) prion protein (PrP) primary sequence;

    (3) Reliable essays can be established to detect CWD infection in humans;and
    *** (4) CWD transmission to humans has already occurred.

    We will test these hypotheses in 4 Aims using transgenic (Tg) mouse models and complementary in vitro approaches.

    Aim 1 will prove that the classical CWD strain may infect humans in brain or peripheral lymphoid tissues at low levels by conducting systemic bioassays in a set of "humanized" Tg mouse lines expressing common human PrP variants using a number of CWD isolates at varying doses and routes. Experimental "human CWD" samples will also be generated for Aim 3.

    Aim 2 will test the hypothesis that the cervid-to-human prion transmission barrier is dependent on prion strain and influenced by the host (human) PrP sequence by examining and comparing the transmission efficiency and phenotypes of several atypical/unusual CWD isolates/strains as well as a few prion strains from other species that have adapted to cervid PrP sequence, utilizing the same panel of humanized Tg mouse lines as in Aim 1.
    Aim 3 will establish reliable essays for detection and surveillance of CWD infection in humans by examining in details the clinical, pathological, biochemical and in vitro seeding properties of existing and future experimental "human CWD" samples generated from Aims 1-2 and compare them with those of common sporadic human Creutzfeldt-Jakob disease (sCJD) prions.

    Aim 4 will attempt to detect clinical CWD-affected human cases by examining a significant number of brain samples from prion-affected human subjects in the USA and Canada who have consumed venison from CWD-endemic areas utilizing the criteria and essays established in Aim 3. The findings from this proposal will greatly advance our understandings on the potential and characteristics of cervid prion transmission in humans, establish reliable essays for CWD zoonosis and potentially discover the first case(s) of CWD infection in humans.
    Public Health Relevance There are significant and increasing human exposure to cervid prions because chronic wasting disease (CWD, a widespread and highly infectious prion disease among deer and elk in North America) continues spreading and consumption of venison remains popular, but our understanding on cervid-to-human prion transmission is still very limited, raising public health concerns. This proposal aims to define the zoonotic risks of cervid prions and set up and apply essays to detect CWD zoonosis using mouse models and in vitro methods. The findings will greatly expand our knowledge on the potentials and characteristics of cervid prion transmission in humans, establish reliable essays for such infections and may discover the first case(s) of CWD infection in humans.

    Proof positive of the lengths one will go to link sporadic CJD with CWD, when no such link exists....anywhere. Fear-mongering anti-meat agenda, pure and simple. This "Crusade" of yours started by trying to link cattle to sporadic CJD. When that failed, you moved on to deer and CWD. Your agenda-driven history is well known and well documented in multiple other states. Michigan is just next on your list, until people here wise up to your agenda as well.

    otcarcher, you are either not paying attention, or your just oblivious to science, or just another person from the industry (take your pick) that likes to pass fake news/science, either way, i don't care, the science speaks for itself, and anyone with any kind of brain can see for themselves, and make their own minds up. as i said before, go to pubmed and search the word sporadic or spontaneous, and there is a laundry list of different diseases linked to both, simply meaning they don't know. sporadic alone hits 51329 hits, see;

    https://www.ncbi.nlm.nih.gov/pubmed/?term=sporadic

    BUT now, science has shown that indeed BSE, Scrapie, and CWD, can and has been linked to sporadic spontaneous creutzfeldt jakob disease sCJD by peer review studies, by scientist. but to have a Government admit that in print has not happened yet. with nvCJD to BSE it took 10 years and the science was staring them in the face, as now CWD TSE Prion in cervid. i just posted all the latest peer review science here, no advertisements, not making any money from this, it's just science, for those that want see for themselves, all the source links are there, it's just science, don't be scared, make your own minds up for Petes sake, or, just take old otcarcher, post: 6656454, member: 103301 word for it...LMAO!

    2014

    ***Moreover, L-BSE has been transmitted more easily to transgenic mice overexpressing a human PrP [13,14] or to primates [15,16] than C-BSE.

    ***It has been suggested that some sporadic CJD subtypes in humans may result from an exposure to the L-BSE agent.

    *** Lending support to this hypothesis, pathological and biochemical similarities have been observed between L-BSE and an sCJD subtype (MV genotype at codon 129 of PRNP) [17], and between L-BSE infected non-human primate and another sCJD subtype (MM genotype) [15].

    snip...

    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4213560/pdf/viruses-06-03766.pdf

    Title: Transmission of scrapie prions to primate after an extended silent incubation period)
    *** In complement to the recent demonstration that humanized mice are susceptible to scrapie, we report here the first observation of direct transmission of a natural classical scrapie isolate to a macaque after a 10-year incubation period. Neuropathologic examination revealed all of the features of a prion disease: spongiform change, neuronal loss, and accumulation of PrPres throughout the CNS.

    *** This observation strengthens the questioning of the harmlessness of scrapie to humans, at a time when protective measures for human and animal health are being dismantled and reduced as c-BSE is considered controlled and being eradicated.
    *** Our results underscore the importance of precautionary and protective measures and the necessity for long-term experimental transmission studies to assess the zoonotic potential of other animal prion strains.

    http://www.ars.usda.gov/research/publications/publications.htm?SEQ_NO_115=313160

    Transmission data also revealed that several scrapie prions propagate in HuPrP-Tg mice with efficiency comparable to that of cattle BSE. While the efficiency of transmission at primary passage was low, subsequent passages resulted in a highly virulent prion disease in both Met129 and Val129 mice.

    Transmission of the different scrapie isolates in these mice leads to the emergence of prion strain phenotypes that showed similar characteristics to those displayed by MM1 or VV2 sCJD prion.

    These results demonstrate that scrapie prions have a zoonotic potential and raise new questions about the possible link between animal and human prions.

    *** WDA 2016 NEW YORK ***

    *** We found that CWD adapts to a new host more readily than BSE and that human PrP was unexpectedly prone to misfolding by CWD prions. In addition, we investigated the role of specific regions of the bovine, deer and human PrP protein in resistance to conversion by prions from another species. We have concluded that the human protein has a region that confers unusual susceptibility to conversion by CWD prions.

    PRION ROUND TABLE CONFERENCE 2018 MAY, 22-25 A REVIEW

    http://prionconference.blogspot.com/2018/02/prion-round-table-conference-2018-may.html

    p.s., but don't forget from day one what BSE Inquiry scientist said;

    Volume 2: Science

    4. The link between BSE and vCJD

    1 Increased ascertainment (ie, increased identification of cases as a result of greater awareness of the condition) seems unlikely, as other groups exposed to risk, such as butchers and veterinarians, do not appear to have been affected. The CJD in farmers seems to be similar to other sporadic CJD in age of onset, in respect to glycosylation patterns, and in strain-typing in experimental mice. Some farmers are heterozygous for the methionine/valine variant at codon 129, and their lymphoreticular system (LRS) does not contain the high levels of PrPSc found in vCJD. It remains a remote possibility that when older people contract CJD from BSE the resulting phenotype is like sporadic CJD and is distinct from the vCJD phenotype in younger people.

    Complete nonsense, Terry. In order for CWD to cause sporadic CJD in humans, it would have to jump the species barrier. There is no evidence of such occurrence anywhere. This is simply more of your unsubstantiated cut and paste fear-mongering anti-meat agenda from a high-school dropout. I understand the science. I have a degree in it.

    Thank You for posting the info. Too bad those that would rather stick their head in the dirt and treat CWD as just a distraction to protect their almighty trophy antler obsession give you so much grief over it. If I ever shoot a deer with CWD I know exactly who I am offering the steaks to, I am sure he would gladly eat a plate full of it seeing as how it is of no concern to him. :lol: Some of us are smart enough to realize Mother Nature finds a way, some of us are blinded by the bones on a deer's head and cannot see that unfortunately. That is what it is I suppose but it is not too hard to see who has the agenda here...so again I thank you for keeping us up to date on this topic. Some of us learned early on that Mother Nature is out to kill us all....others well they would rather pretend all is right in the world if it means they get bigger antlers. I really wonder if some of the big antler guys with an agenda have ever eaten a piece of venison. :sad:

    I'm not sticking my head in the sand at all. I want to see the discussion to remain factual instead of anti-meat agenda driven nonsense. He's attempted to blame the meat industry by connecting cattle to sporadic CJD since the 90's when it took his mom. This discussion has nothing to do with antlers Maxi. It's about sticking with facts, not BS.

    I don't believe you, and I feel your intentions are not genuine, not in the least, deal with it. It is my right to feel that way going from the evidence presented to me over the last couple of years...like I said...deal with it. The possibilities for critters both big and small to morph/evolve is very real. The proof is all around us, the fact that you would rather ignore this just for a few more inches of bone tells me all I need to know. The fact you get away with constantly insulting this man is also a bit beyond belief. I do not allow that type of behavior on my forum, but I do not control this one.........lucky for you. I knew it was a mistake taking you off ignore. I will go fix that mistake now...so please feel free to type away.

    I'm not making this up. It has zero to do with antlers.

    Additionally, I've already sent Steve other links to support my statements. His to choice to share or not. This agenda of Terry's started in Texas, then spread from there.

    otcarcher, post: 6656883, member: 103301, like i said before, sadly, you have nothing, you and your industry have nothing but rhetoric. everything i said back in the old article has come to pass, and you still just can't figure that out, so please, keep posting it. but for others, this link below will explain who they are.

    let's take a closer look shall we ;

    The Center for Consumer Freedom (CCF) (formerly called the "Guest Choice Network (GCN)") is a front group for the restaurant, alcohol and tobacco industries. It runs media campaigns which oppose the efforts of scientists, doctors, health advocates, environmentalists and groups like Mothers Against Drunk Driving, calling them "the Nanny Culture -- the growing fraternity of food cops, health care enforcers, anti-meat activists, and meddling bureaucrats who 'know what's best for you.'"

    CCF is registered as a tax-exempt, non-profit organization under the IRS code 501(c)(3). Its advisory board is comprised mainly of representatives from the restaurant, meat and alcoholic beverage industries.

    otcarcher, post: 6656883, member: 103301, you and your cervid captive farming industry buddies bring nothing but rhetoric to the table. that is why you are a big part of the problem, and will continue to be so imo. especially if they have you as a spokesperson...LOL!

    Yea, you said the same thing in Texas and Iowa too. Antlers had nothing to do with them calling you out either. Your anti-meat agenda has spread from Texas to the the North. It's now Michigan's turn to be exposed to your absolute nonsense. You had one goal from the start, to link meat to the death of your loved one . You couldn't link cattle, now you're moving to deer and venison. What better way to end hunting than to instill fear in hunters that meat will kill them. 

    And the fear-mongering continues in your recent ramblings trying to link sCJD with CWD. It doesn't exist. Not according to the CDC, or the WHO, or the Neurological Institutes of various states. You'll post links ad nauseum but completely ignore the 10 other studies that refute it. You aren't looking for a factual conversation, you're looking for a scapegoat.

    But hey, maybe if you cut and paste enough nonsense you know absolutely zero about, you'll succeed in blaming venison where you failed in blaming cattle.

    So this is Terry Singletary? While I feel for his loss due to CJD he has shown himself over the years to be a shrill alarmist who works tirelessly to frighten people without any sound science behind his rants.

    Terry Singletary — A retired machinist and high school dropout, Terry Singletary suffered the tragic loss of his mother to “sporadic” Creutzfeldt-Jakob disease (CJD) in 1997. Desperate to find an explanation for his mother’s death, he has devoted himself to the sad and fruitless task of connecting her death to her diet. Various reports confirm that Mrs. Singletary’s life was claimed by the most common sub-type of CJD (one that accounts for 70 percent of “sporadic” cases). Sporadic CJD, unlike its newer “variant,” is not linked to meat.
    As the self-appointed international coordinator of CJD Watch, an organization he co-founded with social worker Deborah Oney, Singletary is cited in media reports as an apparent expert on tracking mad cow disease. This despite his lack of formal education and the absence for support from any credible academic, medical or scientific authority. His sensationalist allegations about the safety of U.S. beef have found their way into hundreds of newspapers and broadcasts. Singletary moderates a mad-cow discussion forum run by a vegetarian activist group; his contributions account for more than half the traffic on the “BSE-L” mailing list, which is generally read by real scientists. Animal rights activists and other food-scare artists frequently refer to him as “Dr. Terry Singletary,” apparently an honorary degree as he has yet to finish high school.
    Like many activists, Singletary ignores overwhelming epidemiological and laboratory evidence that rules out a connection between sporadic CJD and beef. Relying entirely on shallow circumstantial evidence and frequent repetition of claims which have been publicly refuted as false, he also blindly insists upon a mad-cow with Alzheimer’s, Parkinson’s, and Lou Gehrig’s disease. His specific allegations have been clearly refuted by Centers for Disease Countrol and Prevention scientists in the journalNeurology


    Hope this helps with your questions about Terry the "Flounder"

    The bottom line......
    These links are being shared ad nauseum in multiple forums across the country by a fear-mongering anti-meat zealot, who is a high school dropout retired machinist with absolutely no formal college education or experience in this field of study.

    O.05: Transmission of prions to primates after extended silent incubation periods: Implications for BSE and scrapie risk assessment in human populations Emmanuel Comoy, Jacqueline Mikol, Valerie Durand, Sophie Luccantoni, Evelyne Correia, Nathalie Lescoutra, Capucine Dehen, and Jean-Philippe Deslys Atomic Energy Commission; Fontenay-aux-Roses, France Prion diseases (PD) are the unique neurodegenerative proteinopathies reputed to be transmissible under field conditions since decades. The transmission of Bovine Spongiform Encephalopathy (BSE) to humans evidenced that an animal PD might be zoonotic under appropriate conditions. Contrarily, in the absence of obvious (epidemiological or experimental) elements supporting a transmission or genetic predispositions, PD, like the other proteinopathies, are reputed to occur spontaneously (atpical animal prion strains, sporadic CJD summing 80% of human prion cases). Non-human primate models provided the first evidences supporting the transmissibiity of human prion strains and the zoonotic potential of BSE. Among them, cynomolgus macaques brought major information for BSE risk assessment for human health (Chen, 2014), according to their phylogenetic proximity to humans and extended lifetime. We used this model to assess the zoonotic potential of other animal PD from bovine, ovine and cervid origins even after very long silent incubation periods.

    *** We recently observed the direct transmission of a natural classical scrapie isolate to macaque after a 10-year silent incubation period,

    ***with features similar to some reported for human cases of sporadic CJD, albeit requiring fourfold long incubation than BSE. Scrapie, as recently evoked in humanized mice (Cassard, 2014),

    ***is the third potentially zoonotic PD (with BSE and L-type BSE),

    ***thus questioning the origin of human sporadic cases.

    We will present an updated panorama of our different transmission studies and discuss the implications of such extended incubation periods on risk assessment of animal PD for human health.

    ***thus questioning the origin of human sporadic cases***

    WS-01: Prion diseases in animals and zoonotic potential

    Transmission data also revealed that several scrapie prions propagate in HuPrP-Tg mice with efficiency comparable to that of cattle BSE. While the efficiency of transmission at primary passage was low, subsequent passages resulted in a highly virulent prion disease in both Met129 and Val129 mice.
    Transmission of the different scrapie isolates in these mice leads to the emergence of prion strain phenotypes that showed similar characteristics to those displayed by MM1 or VV2 sCJD prion.

    These results demonstrate that scrapie prions have a zoonotic potential and raise new questions about the possible link between animal and human prions.

    why do we not want to do TSE transmission studies on chimpanzees $

    5. A positive result from a chimpanzee challenged severly would likely create alarm in some circles even if the result could not be interpreted for man. I have a view that all these agents could be transmitted provided a large enough dose by appropriate routes was given and the animals kept long enough. Until the mechanisms of the species barrier are more clearly understood it might be best to retain that hypothesis.

    Title: Transmission of scrapie prions to primate after an extended silent incubation period)

    *** In complement to the recent demonstration that humanized mice are susceptible to scrapie, we report here the first observation of direct transmission of a natural classical scrapie isolate to a macaque after a 10-year incubation period. Neuropathologic examination revealed all of the features of a prion disease: spongiform change, neuronal loss, and accumulation of PrPres throughout the CNS.

    *** This observation strengthens the questioning of the harmlessness of scrapie to humans, at a time when protective measures for human and animal health are being dismantled and reduced as c-BSE is considered controlled and being eradicated.

    *** Our results underscore the importance of precautionary and protective measures and the necessity for long-term experimental transmission studies to assess the zoonotic potential of other animal prion strains.

    And just like in Texas, Iowa, New York, and elsewhere....Terry continues the anti-meat, anti-hunting, PETA agenda by calling those who call him out for exactly who he is as "Captive Game Farmers". We are not, nor are we apologetic to them. It's time for you and PETA to stop the fear-mongering here.

    *** WDA 2016 NEW YORK ***

    *** We found that CWD adapts to a new host more readily than BSE and that human PrP was unexpectedly prone to misfolding by CWD prions. In addition, we investigated the role of specific regions of the bovine, deer and human PrP protein in resistance to conversion by prions from another species. We have concluded that the human protein has a region that confers unusual susceptibility to conversion by CWD prions.

    First evidence of intracranial and peroral transmission of Chronic Wasting Disease (CWD) into Cynomolgus macaques: a work in progress

    University of Calgary Faculty of Veterinary Medicine/Canadian Food Inspection Agency; 2Universitatsklinikum des Saarlandes und Medizinische Fakultat der Universitat des Saarlandes; 3 Deutsches Primaten Zentrum/Goettingen; 4 Robert-Koch-Institut Berlin; 5 University of Calgary Faculty of Veterinary Medicine; 6 presently: Boehringer Ingelheim Veterinary Research Center; previously: Deutsches Primaten Zentrum/Goettingen

    This is a progress report of a project which started in 2009. 21 cynomolgus macaques were challenged with characterized CWD material from white-tailed deer (WTD) or elk by intracerebral (ic), oral, and skin exposure routes. Additional blood transfusion experiments are supposed to assess the CWD contamination risk of human blood product. Challenge materials originated from symptomatic cervids for ic, skin scarification and partially per oral routes (WTD brain). Challenge material for feeding of muscle derived from preclinical WTD and from preclinical macaques for blood transfusion experiments. We have confirmed that the CWD challenge material contained at least two different CWD agents (brain material) as well as CWD prions in muscle-associated nerves.

    Here we present first data on a group of animals either challenged ic with steel wires or per orally and sacrificed with incubation times ranging from 4.5 to 6.9 years at postmortem. Three animals displayed signs of mild clinical disease, including anxiety, apathy, ataxia and/or tremor. In four animals wasting was observed, two of those had confirmed diabetes. All animals have variable signs of prion neuropathology in spinal cords and brains and by supersensitive IHC, reaction was detected in spinal cord segments of all animals. Protein misfolding cyclic amplification (PMCA), real-time quaking-induced conversion (RT-QuiC) and PET-blot assays to further substantiate these findings are on the way, as well as bioassays in bank voles and transgenic mice.

    At present, a total of 10 animals are sacrificed and read-outs are ongoing. Preclinical incubation of the remaining macaques covers a range from 6.4 to 7.10 years. Based on the species barrier and an incubation time of > 5 years for BSE in macaques and about 10 years for scrapie in macaques, we expected an onset of clinical disease beyond 6 years post inoculation.

    > However, to date, no CWD infections have been reported in people.

    key word here is 'reported'. science has shown that CWD in humans will look like sporadic CJD. SO, how can one assume that CWD has not already transmitted to humans? they can't, and it's as simple as that. from all recorded science to date, CWD has already transmitted to humans, and it's being misdiagnosed as sporadic CJD. ...terry

    LOOKING FOR CWD IN HUMANS AS nvCJD or as an ATYPICAL CJD, LOOKING IN ALL THE WRONG PLACES $$$

    *** These results would seem to suggest that CWD does indeed have zoonotic potential, at least as judged by the compatibility of CWD prions and their human PrPC target. Furthermore, extrapolation from this simple in vitro assay suggests that if zoonotic CWD occurred, it would most likely effect those of the PRNP codon 129-MM genotype and that the PrPres type would be similar to that found in the most common subtype of sCJD (MM1).***

    Alzheimer’s disease, iatrogenic, and Transmissible Spongiform Encephalopathy TSE Prion disease, that is the question ???

    >>> The only tenable public line will be that "more research is required’’ <<<

    >>> possibility on a transmissible prion remains open<<<

    O.K., so it’s about 23 years later, so somebody please tell me, when is "more research is required’’ enough time for evaluation ?

    [9. Whilst this matter is not at the moment directly concerned with the iatrogenic CJD cases from hgH, there remains a possibility of litigation here, and this presents an added complication. There are also results to be made available shortly (1) concerning a farmer with CJD who had BSE animals, (2) on the possible transmissibility of Alzheimer’s and (3) a CMO letter on prevention of iatrogenic CJD transmission in neurosurgery, all of which will serve to increase media interest.]

Samples positive for CWD from depopulated deer farm

News Release

Samples positive for CWD from depopulated deer farm The Minnesota Board of Animal Health received positive test results for chronic wasting disease (CWD) this week after depopulating a Winona County deer farm first identified with the disease in November 2017. All seven of the remaining white-tailed deer in the herd were harvested, sampled, and found to have the disease affecting deer and elk.

The producer had also moved deer into the Winona City Park, and those three animals were considered exposed to CWD and tested. Results showed no CWD was detected in samples collected from those animals. The next step in the Board’s CWD response is to work with the herd owner to clean and decontaminate the enclosure that contained the positive deer.

“The response to the initial CWD detection and plan to depopulate and test the herd went very well,” said Dr. Linda Glaser, Board of Animal Health assistant director and cervid program manager. “We had the herd owner’s full cooperation, and the support of the USDA and DNR as we investigated the extent of the disease in this herd.”

Only one farmed deer herd found infected with CWD in Minnesota has not been depopulated. That herd is currently quarantined and monitored by the Board. An update on that herd was issued in November 2017 [click this link to read the update].

CWD is a disease of the deer and elk family caused by an abnormally shaped protein, a prion, which can damage brain and nerve tissue. The disease is most likely transmitted when infected deer and elk shed prions in saliva, feces, urine, and other fluids or tissues. CWD is not known to naturally occur in other animals. The disease is fatal in deer and elk, and there are no known treatments or vaccines. Consuming infected meat is not advised.

Minnesota Tests confirm 2 CWD-positive deer near Lanesboro


TESTS CONFIRM 2 CWD-POSITIVE DEER NEAR LANESBORO

DNR initiates disease response plan; offers hunters information on field dressing

Test results show two deer harvested by hunters in southeastern Minnesota were infected with Chronic Wasting Disease, according to the Department of Natural Resources. 

One deer has been confirmed as CWD-positive. Confirmation of the second is expected later this week. The deer, both male, were killed near Lanesboro in Fillmore County during the first firearms deer season.

The two deer were harvested approximately 1 mile apart. These are the only deer to test positive from 2,493 samples collected Nov. 5-13. Results are still pending from 373 additional test samples collected during the opening three days of the second firearms season, Nov. 19-21.

CWD is a fatal brain disease to deer, elk and moose but is not known to affect human health. While it is found in deer in states bordering southeastern Minnesota, it was only found in a single other wild deer in Minnesota in 2010.

The DNR discovered the disease when sampling hunter-killed deer this fall in southeastern Minnesota as part of its CWD surveillance program. Dr. Lou Cornicelli, DNR wildlife research manager, said hunter and landowner cooperation on disease surveillance is the key to keeping the state’s deer herd healthy.

“We were proactively looking for the disease, a proven strategy that allows us to manage CWD by finding it early, reacting quickly and aggressively to control it and hopefully eliminating its spread,” he said.

It is unknown how the two CWD-positive deer, which were harvested 4 miles west of Lanesboro in deer permit area 348, contracted the disease, Cornicelli said.

“We want to thank hunters who have brought their deer to our check stations for sampling,” he said. “While finding CWD-positive deer is disappointing, we plan to work with hunters, landowners and other organizations to protect the state’s deer herd and provide hunters the opportunity to pass on their deer hunting traditions.”

These are the first wild deer found to have CWD since a deer harvested in fall 2010 near Pine Island tested positive. It was found during a successful disease control effort prompted by the detection in 2009 of CWD on a domestic elk farm. The DNR, landowners and hunters worked together to sample more than 4,000 deer in the Pine Island area from 2011 to 2013, and no additional infected deer were found.

The National Centers for Disease Control and Prevention as well as the World Health Organization have found no scientific evidence that the disease presents a health risk to humans who come in contact with infected animals or eat infected meat. Still, the CDC advises against eating meat from animals known to have CWD...

CHRONIC WASTING DISEASE UPDATE September 6, 2002 

Minnesota has announced the finding of CWD in a captive elk in Aitkin County. The animal was a five-year-old male. It had been purchased from a captive facility in Stearns County in August of 2000. The herd where the elk was found has been placed under quarantine as has two additional facilities where the infected elk had resided prior to it coming to the farm in Aitkin County. Minnesota DNR officials will test wild deer in the area to determine if there is any sign of CWD in the free-ranging population. This is the first case of CWD in either captive or freeranging cervids in Minnesota. Several more states have passed bans on the importation of deer and elk carcasses from states where CWD has been found in wild animals. Previously the states of Colorado, Illinois and Iowa and the province of Manitoba had passed such bans. The states of Vermont, Oregon and Missouri have enacted similar bans. Numerous states have issue voluntary advisories to their out-of-state hunters encouraging them not to bring the carcass or carcass parts of deer and elk into their state. The bans do permit the importation of boned out meat, hides or cape with no meat attached, clean skull cap with antler attached, finished taxidermy heads or the ivories of elk. The state of Georgia has recently banned the importation of live cervids into that state also. Some citizens of Colorado have formed a new political action group called Colorado Wildlife Defense (just happens that the acronym is CWD). The stated goal of this group are; Elimination of big game diseases, especially CWD; promotion of healthy wildlife habitat; promotion of scientifically sound wildlife research; promotion of a discussion of the ethics of hunting and wildlife management; education of the hunting and non hunting public. Their action plan calls for; requiring double fencing of all game farms at owners expense; all game farmers provide annual proof of bonding; prohibit new licenses for deer and elk farms; prohibit expansion in acreage of existing game farms; prohibit the transfer of game farm licenses; prohibit charging for hunting behind high wire; prohibit blocking of traditional migratory paths by high fences; requiring game farms to maintain environmental controls and prohibit the escape of contaminated water or soil; requiring immediate reporting of missing deer or elk from game farms; and requiring all game farm deer and elk to be tested for brucellosis and TB. Wisconsin has announced that 7 more free-ranging deer have tested positive for CWD. They have expanded their eradication zone by an additional 15 square miles to cover these findings. The total number of free-ranging CWD positive in Wisconsin is now 31 white-tail deer. 

In 2000, a elk farmer in Wisconsin received elk from a CWD exposed herd in Colorado. At that time, the farmer advised the Wisconsin Department of Agriculture that both animals from the exposed herd in Colorado were dead. He has now advised Wisconsin Ag. that he was mistaken and that one of the animals is still alive in his herd. The second draft of the implementation documents for the National CWD Plan was distributed to committee members and others on Friday, August 30. The final documents are due to APHIS and USFWS on Friday, September 13. The herd of captive elk in Oklahoma that had been exposed to CWD will be destroyed this week. This herd had an elk test positive for CWD in 1997 but the depopulation of the herd was not agreed to by the owners and federal representatives until this week. Since the discovery of CWD in the herd, the remaining animals have been under quarantine, however, in the meantime the herd has dropped from 150 animals to 74. Due to a lack of communication, not all of the 76 animals that died in the interim were tested for CWD. All remaining animals will be tested but the true degree of infection rate of the herd will never be known. 

The owners of the facility will not be permitted to restock the area with cervids for a period of five years. A New York based organization, BioTech Research Fund I LLC has committed a $1 million line of credit to fund commercialization of tests for brain-wasting disorders and production of various vaccines to Gene-Thera of Wheat Ridge, Colorado. Gene-Thera has spent three years developing new ways not only to diagnose CWD, but create vaccines for mad cow disease, E. coli contaminants and foot-and-mouth disease. Its tests for CWD have been successful in more than 100 samples from Colorado and Wisconsin according to company officials. Gene-Thera plans to license and market some o fits disease test kits by the end of the year, then begin volume distribution by mid-2003. The abstracts of the presentations from the CWD Conference in Denver August 6 and 7 have been posted on the Colorado Division of Wildlife web site. You will need adobe acrobat reader to read them.

Supporting Documents: Colorado: CWD-Exposed Elk Used in 1990 Study- Wildlife officials call W. Slope move a mistake 

Date: January 17, 2003 Source: Denver Post Contacts: Theo Stein Environment Writer 

The Colorado Division of Wildlife knowingly used a herd of captive elk exposed to chronic wasting disease in a grazing study on the Western Slope in January 1990, possibly introducing the disease to the elk-rich area. "It was a bad call," said Jeff Ver Steeg, the division's top game manager. "I can't deny it." About 150 wild elk were allowed to graze in the same pens near Maybell after the research herd was removed and may have picked up the abnormal protein that causes the disease from the feces and urine left by the captive elk. While the Division of Wildlife has expressed concern before that its animals might have helped spread CWD, this is the first time the agency has acknowledged it knowingly moved elk exposed to CWD deep into an area where the disease was not known to already exist. Studies that could help determine the source of CWD on the Western Slope are incomplete, and officials say what data that do exist are so new and so spotty they may not provide all the answers. So far, it appears that less than 1 percent of deer and elk in the area are infected, compared with as much as 15 to 20 percent in hotspots in northeastern Colorado. But as wildlife officials grapple with CWD's appearance in northwestern Colorado, officials now admit the decision to continue the grazing study over the objections of some biologists was an error. At the time, biologists wanted to see whether elk grazing on winter range depleted forage that ranchers wanted for fattening cattle in spring. "I think in hindsight a lot of good people probably did some dumb things, myself included," said Bruce Gill, a retired wildlife manager who oversaw research efforts and remembers the debate over the project. "Had we known CWD would explode into such a potentially volatile ecologic and economic issue, we wouldn't have done it." Elk ranchers, who have been blamed for exporting the disease from its stronghold on the Colorado and Wyoming plains to seven states and two Canadian provinces, say the agency's belated disclosure smacks of a coverup. "It's pure negligence," said Jerry Perkins, a Delta banker and rancher who is now demanding a legislative inquiry. "If I'd have moved animals I knew to be infected around like that, I'd be in jail." Grand Junction veterinarian and sportsman Dick Steele said he faults the agency for not disclosing information about CWD-exposed research animals before October, when information was posted on the Division of Wildlife website. "This went way beyond poor judgment," he said. "My main concern is that this has been hidden for the last 12 years. It would have been real important to our decision-making process on how to deal with CWD." While the Maybell information is new, Perkins and other ranchers have long suspected Division of Wildlife research facilities near Meeker and Kremmling, which temporarily housed mule deer kept in heavily infected pens at the Fort Collins facility, have leaked CWD to the wild. Fear of an outbreak led the agency to sample 450 deer around the Meeker and Kremmling facilities. None tested positive, but the sample size was only large enough to detect cases if the infection rate was greater than 1 percent. This fall, tests on 23,000 deer and elk submitted by hunters statewide have revealed 48 CWD cases north of Interstate 70 and west of the Continental Divide. Biologists believe the infection rate in that area, which includes the Maybell, Meeker and Kremmling sites, is still well below 1 percent. But CWD has never been contained in a wild population, so experts fear the problem will grow worse. 

The Division of Wildlife says it will be months before a statistical analysis of the fall's sampling results can be completed, an exercise that may shed light on the disease's origin on the Western Slope. "We're just not going to speculate at this point," said Ver Steeg of the possible Maybell connection. "This is one possibility, but certainly not the only possibility." Some biologists think a defunct elk ranch near Pagoda, which had dozens of unexplained deaths in the mid-'90s, is another, a suggestion Perkins rejects. "It may be inconclusive to them," said Perkins. "It isn't inconclusive to us." 


To date, 19 CWD-positive animals have been found on six Wisconsin farms. 

*** All have been white-tailed deer except for one elk imported from a Minnesota herd later found to be infected. 

More than 8,000 farm-raised deer and elk have been tested in Wisconsin, and about 540 herds are enrolled in the CWD monitoring program. 

 
CWD disease detected on Lac qui Parle County cervid farm southwestern Minnesota (2006-03-15) 

Date: March 15, 2006 at 12:36 pm PST 

Chronic wasting disease detected on Lac qui Parle County cervid farm (2006-03-15) The Board of Animal Health announced today that chronic wasting disease (CWD) has been detected in one domestic white-tailed deer on a cervid farm in Lac qui Parle County, which is located in southwestern Minnesota. 

Immediately, DNR officials will conduct a local deer survey to determine the number of wild deer in the area. It is expected that not many deer will be found because the area is highly agricultural, with little deer habitat surrounding the farm. DNR will conduct opportunistic sampling of deer, like road kills, in the immediate area now and will conduct intensive hunter-harvested surveillance during the 2006 firearm deer season. 

Although this positive animal is a captive deer, DNR has conducted surveillance for CWD in wild deer in the area. The farm is located near the northern boundary of deer permit area 447, where wild deer surveillance for CWD last occurred in 2003. 

Lou Cornicelli, DNR big game program coordinator, said, "In 2003, we conducted wild deer CWD surveillance in adjoining permit areas 433, 446 and 447. In total, we collected 392 samples from those permit areas during the regular firearm deer season and CWD was not detected." 

The sampling of wild deer was designed statistically to have a 95 percent confidence of detecting a 1 percent infection rate, according to Mike DonCarlos, DNR wildlife programs manager. 

"This situation is very similar to the positive elk farm discovered in Stearns County in 2003, which followed the first discovery of CWD in an Aitkin County elk farm," DonCarlos said. “The DNR response will be similar to the Stearns County action and will include an initial assessment of wild deer populations in the area and development of a surveillance program for next fall." 

From 2002 to 2004, DNR staff collected nearly 28,000 CWD samples statewide and no disease found in the wild herd. 

"The intensive surveillance conducted in 2003 indicated CWD was not present in wild deer," Cornicelli said. “In addition, all indications are that this positive captive deer has not contacted any wild deer, but we will conduct additional surveillance this fall to be sure."

O.05: Transmission of prions to primates after extended silent incubation periods: Implications for BSE and scrapie risk assessment in human populations Emmanuel Comoy, Jacqueline Mikol, Valerie Durand, Sophie Luccantoni, Evelyne Correia, Nathalie Lescoutra, Capucine Dehen, and Jean-Philippe Deslys Atomic Energy Commission; Fontenay-aux-Roses, France Prion diseases (PD) are the unique neurodegenerative proteinopathies reputed to be transmissible under field conditions since decades. The transmission of Bovine Spongiform Encephalopathy (BSE) to humans evidenced that an animal PD might be zoonotic under appropriate conditions. Contrarily, in the absence of obvious (epidemiological or experimental) elements supporting a transmission or genetic predispositions, PD, like the other proteinopathies, are reputed to occur spontaneously (atpical animal prion strains, sporadic CJD summing 80% of human prion cases). Non-human primate models provided the first evidences supporting the transmissibiity of human prion strains and the zoonotic potential of BSE. Among them, cynomolgus macaques brought major information for BSE risk assessment for human health (Chen, 2014), according to their phylogenetic proximity to humans and extended lifetime. We used this model to assess the zoonotic potential of other animal PD from bovine, ovine and cervid origins even after very long silent incubation periods. 

*** We recently observed the direct transmission of a natural classical scrapie isolate to macaque after a 10-year silent incubation period, 

***with features similar to some reported for human cases of sporadic CJD, albeit requiring fourfold long incubation than BSE. Scrapie, as recently evoked in humanized mice (Cassard, 2014), 

***is the third potentially zoonotic PD (with BSE and L-type BSE), 

***thus questioning the origin of human sporadic cases. 

We will present an updated panorama of our different transmission studies and discuss the implications of such extended incubation periods on risk assessment of animal PD for human health.

Dietary exposure to bovine spongiform encephalopathy (BSE) contaminated bovine tissues is considered as the origin of variant Creutzfeldt Jakob (vCJD) disease in human. To date, BSE agent is the only recognized zoonotic prion. Despite the variety of Transmissible Spongiform Encephalopathy (TSE) agents that have been circulating for centuries in farmed ruminants there is no apparent epidemiological link between exposure to ruminant products and the occurrence of other form of TSE in human like sporadic Creutzfeldt Jakob Disease (sCJD). However, the zoonotic potential of the diversity of circulating TSE agents has never been systematically assessed. The major issue in experimental assessment of TSEs zoonotic potential lies in the modeling of the ‘species barrier‘, the biological phenomenon that limits TSE agents’ propagation from a species to another. In the last decade, mice genetically engineered to express normal forms of the human prion protein has proved essential in studying human prions pathogenesis and modeling the capacity of TSEs to cross the human species barrier.

To assess the zoonotic potential of prions circulating in farmed ruminants, we study their transmission ability in transgenic mice expressing human PrPC (HuPrP-Tg). Two lines of mice expressing different forms of the human PrPC (129Met or 129Val) are used to determine the role of the Met129Val dimorphism in susceptibility/resistance to the different agents.

These transmission experiments confirm the ability of BSE prions to propagate in 129M- HuPrP-Tg mice and demonstrate that Met129 homozygotes may be susceptible to BSE in sheep or goat to a greater degree than the BSE agent in cattle and that these agents can convey molecular properties and neuropathological indistinguishable from vCJD. However homozygous 129V mice are resistant to all tested BSE derived prions independently of the originating species suggesting a higher transmission barrier for 129V-PrP variant.

Transmission data also revealed that several scrapie prions propagate in HuPrP-Tg mice with efficiency comparable to that of cattle BSE. While the efficiency of transmission at primary passage was low, subsequent passages resulted in a highly virulent prion disease in both Met129 and Val129 mice. 

Transmission of the different scrapie isolates in these mice leads to the emergence of prion strain phenotypes that showed similar characteristics to those displayed by MM1 or VV2 sCJD prion. 

These results demonstrate that scrapie prions have a zoonotic potential and raise new questions about the possible link between animal and human prions. 


why do we not want to do TSE transmission studies on chimpanzees $

5. A positive result from a chimpanzee challenged severly would likely create alarm in some circles even if the result could not be interpreted for man. I have a view that all these agents could be transmitted provided a large enough dose by appropriate routes was given and the animals kept long enough. Until the mechanisms of the species barrier are more clearly understood it might be best to retain that hypothesis.

Title: Transmission of scrapie prions to primate after an extended silent incubation period) 

*** In complement to the recent demonstration that humanized mice are susceptible to scrapie, we report here the first observation of direct transmission of a natural classical scrapie isolate to a macaque after a 10-year incubation period. Neuropathologic examination revealed all of the features of a prion disease: spongiform change, neuronal loss, and accumulation of PrPres throughout the CNS. 

*** This observation strengthens the questioning of the harmlessness of scrapie to humans, at a time when protective measures for human and animal health are being dismantled and reduced as c-BSE is considered controlled and being eradicated. 

*** Our results underscore the importance of precautionary and protective measures and the necessity for long-term experimental transmission studies to assess the zoonotic potential of other animal prion strains. 


 *** WDA 2016 NEW YORK *** 

 *** We found that CWD adapts to a new host more readily than BSE and that human PrP was unexpectedly prone to misfolding by CWD prions. In addition, we investigated the role of specific regions of the bovine, deer and human PrP protein in resistance to conversion by prions from another species. We have concluded that the human protein has a region that confers unusual susceptibility to conversion by CWD prions.

key word here is 'reported'. science has shown that CWD in humans will look like sporadic CJD. SO, how can one assume that CWD has not already transmitted to humans? they can't, and it's as simple as that. from all recorded science to date, CWD has already transmitted to humans, and it's being misdiagnosed as sporadic CJD. ...terry

*** These results would seem to suggest that CWD does indeed have zoonotic potential, at least as judged by the compatibility of CWD prions and their human PrPC target. Furthermore, extrapolation from this simple in vitro assay suggests that if zoonotic CWD occurred, it would most likely effect those of the PRNP codon 129-MM genotype and that the PrPres type would be similar to that found in the most common subtype of sCJD (MM1).***

First evidence of intracranial and peroral transmission of Chronic Wasting Disease (CWD) into Cynomolgus macaques: a work in progress

This is a progress report of a project which started in 2009. 21 cynomolgus macaques were challenged with characterized CWD material from white-tailed deer (WTD) or elk by intracerebral (ic), oral, and skin exposure routes. Additional blood transfusion experiments are supposed to assess the CWD contamination risk of human blood product. Challenge materials originated from symptomatic cervids for ic, skin scarification and partially per oral routes (WTD brain). Challenge material for feeding of muscle derived from preclinical WTD and from preclinical macaques for blood transfusion experiments. We have confirmed that the CWD challenge material contained at least two different CWD agents (brain material) as well as CWD prions in muscle-associated nerves. 

Here we present first data on a group of animals either challenged ic with steel wires or per orally and sacrificed with incubation times ranging from 4.5 to 6.9 years at postmortem. Three animals displayed signs of mild clinical disease, including anxiety, apathy, ataxia and/or tremor. In four animals wasting was observed, two of those had confirmed diabetes. All animals have variable signs of prion neuropathology in spinal cords and brains and by supersensitive IHC, reaction was detected in spinal cord segments of all animals. Protein misfolding cyclic amplification (PMCA), real-time quaking-induced conversion (RT-QuiC) and PET-blot assays to further substantiate these findings are on the way, as well as bioassays in bank voles and transgenic mice. 

At present, a total of 10 animals are sacrificed and read-outs are ongoing. Preclinical incubation of the remaining macaques covers a range from 6.4 to 7.10 years. Based on the species barrier and an incubation time of > 5 years for BSE in macaques and about 10 years for scrapie in macaques, we expected an onset of clinical disease beyond 6 years post inoculation.

Dear Mr Elmhirst,

CREUTZFELDT-JAKOB DISEASE (CJD) SURVEILLANCE UNIT REPORT

Thank you for your recent letter concerning the publication of the third annual report from the CJD Surveillance Unit. I am sorry that you are dissatisfied with the way in which this report was published.

The Surveillance Unit is a completely independant outside body and the Department of Health is committed to publishing their reports as soon as they become available. In the circumstances it is not the practice to circulate the report for comment since the findings of the report would not be amended. In future we can ensure that the British Deer Farmers Association receives a copy of the report in advance of publication.

The Chief Medical Officer has undertaken to keep the public fully informed of the results of any research in respect of CJD. This report was entirely the work of the unit and was produced completely independantly of the the Department.

The statistical results reqarding the consumption of venison was put into perspective in the body of the report and was not mentioned at all in the press release. Media attention regarding this report was low key but gave a realistic presentation of the statistical findings of the Unit. This approach to publication was successful in that consumption of venison was highlighted only once by the media ie. in the News at one television proqramme.

I believe that a further statement about the report, or indeed statistical links between CJD and consumption of venison, would increase, and quite possibly give damaging credence, to the whole issue. From the low key media reports of which I am aware it seems unlikely that venison consumption will suffer adversely, if at all.

There is some evidence that risk of CJD INCREASES WITH INCREASING FREQUENCY OF LAMB EATING (p = 0.02).

The evidence for such an association between beef eating and CJD is weaker (p = 0.14). When only controls for whom a relative was interviewed are included, this evidence becomes a little STRONGER (p = 0.08).

It was found that when veal was included in the model with another exposure, the association between veal and CJD remained statistically significant (p = < 0.05 for all exposures), while the other exposures ceased to be statistically significant (p = > 0.05).

In conclusion, an analysis of dietary histories revealed statistical associations between various meats/animal products and INCREASED RISK OF CJD. When some account was taken of possible confounding, the association between VEAL EATING AND RISK OF CJD EMERGED AS THE STRONGEST OF THESE ASSOCIATIONS STATISTICALLY. ...

snip...

In the study in the USA, a range of foodstuffs were associated with an increased risk of CJD, including liver consumption which was associated with an apparent SIX-FOLD INCREASE IN THE RISK OF CJD. By comparing the data from 3 studies in relation to this particular dietary factor, the risk of liver consumption became non-significant with an odds ratio of 1.2 (PERSONAL COMMUNICATION, PROFESSOR A. HOFMAN. ERASMUS UNIVERSITY, ROTTERDAM). (???...TSS)

Dear Sir/Madam,

In the Archives of Neurology you quoted (the abstract of which was attached to your email), we did not say CWD in humans will present like variant CJD. That assumption would be wrong. I encourage you to read the whole article and call me if you have questions or need more clarification (phone: 404-639-3091). Also, we do not claim that "no-one has ever been infected with prion disease from eating venison." Our conclusion stating that we found no strong evidence of CWD transmission to humans in the article you quoted or in any other forum is limited to the patients we investigated.

*** The potential impact of prion diseases on human health was greatly magnified by the recognition that interspecies transfer of BSE to humans by beef ingestion resulted in vCJD. While changes in animal feed constituents and slaughter practices appear to have curtailed vCJD, there is concern that CWD of free-ranging deer and elk in the U.S. might also cross the species barrier. Thus, consuming venison could be a source of human prion disease. Whether BSE and CWD represent interspecies scrapie transfer or are newly arisen prion diseases is unknown. Therefore, the possibility of transmission of prion disease through other food animals cannot be ruled out. There is evidence that vCJD can be transmitted through blood transfusion. There is likely a pool of unknown size of asymptomatic individuals infected with vCJD, and there may be asymptomatic individuals infected with the CWD equivalent. These circumstances represent a potential threat to blood, blood products, and plasma supplies.

 ''Results: We assessed archived human biopsy tissues from CWD endemic and non-endemic regions for the presence of abnormal PrP by RT-QuIC. Formalin-fixed, paraffin-embedded histology blocks were processed to extract tissue homogenates. Our study focused on analyzing appendix biopsy samples due to their previous use in surveillance studies and accessibility, but we also show the methodology can be applied to additional lymphoreticular tissues such as tonsils, spleen and lymph nodes. We compared 100 appendix biopsies from patients residing within the chronic wasting disease (CWD) endemic region to 100 appendix biopsies from patients residing outside the CWD endemic region.''

Stereotactic multicontact electrodes used to probe the cerebral cortex of a middle aged woman with progressive dementia were previously implicated in the accidental transmission of Creutzfeldt-Jakob disease (CJD) to two younger patients. The diagnoses of CJD have been confirmed for all three cases. More than two years after their last use in humans, after three cleanings and repeated sterilisation in ethanol and formaldehyde vapour, the electrodes were implanted in the cortex of a chimpanzee. Eighteen months later the animal became ill with CJD. This finding serves to re-emphasise the potential danger posed by reuse of instruments contaminated with the agents of spongiform encephalopathies, even after scrupulous attempts to clean them.

you cannot cook the TSE prion disease out of meat. 

you can take the ash and mix it with saline and inject that ash into a mouse, and the mouse will go down with TSE. 

Prion Infected Meat-and-Bone Meal Is Still Infectious after Biodiesel Production as well. 

the TSE prion agent also survives Simulated Wastewater Treatment Processes. 

IN fact, you should also know that the TSE Prion agent will survive in the environment for years, if not decades. 

you can bury it and it will not go away. 

The TSE agent is capable of infected your water table i.e. Detection of protease-resistant cervid prion protein in water from a CWD-endemic area. 

it’s not your ordinary pathogen you can just cook it out and be done with. 

that’s what’s so worrisome about Iatrogenic mode of transmission, a simple autoclave will not kill this TSE prion agent.

DEFRA U.K. What is the risk of Chronic Wasting Disease CWD being introduced into Great Britain? A Qualitative Risk Assessment October 2012

snip...

In the USA, under the Food and Drug Administration's BSE Feed Regulation (21 CFR 589.2000) most material (exceptions include milk, tallow, and gelatin) from deer and elk is prohibited for use in feed for ruminant animals. With regards to feed for non-ruminant animals, under FDA law, CWD positive deer may not be used for any animal feed or feed ingredients. For elk and deer considered at high risk for CWD, the FDA recommends that these animals do not enter the animal feed system. However, this recommendation is guidance and not a requirement by law.

Animals considered at high risk for CWD include:

1) animals from areas declared to be endemic for CWD and/or to be CWD eradication zones and

2) deer and elk that at some time during the 60-month period prior to slaughter were in a captive herd that contained a CWD-positive animal.

Therefore, in the USA, materials from cervids other than CWD positive animals may be used in animal feed and feed ingredients for non-ruminants.

The amount of animal PAP that is of deer and/or elk origin imported from the USA to GB can not be determined, however, as it is not specified in TRACES. It may constitute a small percentage of the 8412 kilos of non-fish origin processed animal proteins that were imported from US into GB in 2011.

Overall, therefore, it is considered there is a __greater than negligible risk___ that (nonruminant) animal feed and pet food containing deer and/or elk protein is imported into GB.

There is uncertainty associated with this estimate given the lack of data on the amount of deer and/or elk protein possibly being imported in these products.

snip...

36% in 2007 (Almberg et al., 2011). In such areas, population declines of deer of up to 30 to 50% have been observed (Almberg et al., 2011). In areas of Colorado, the prevalence can be as high as 30% (EFSA, 2011).

The clinical signs of CWD in affected adults are weight loss and behavioural changes that can span weeks or months (Williams, 2005). In addition, signs might include excessive salivation, behavioural alterations including a fixed stare and changes in interaction with other animals in the herd, and an altered stance (Williams, 2005). These signs are indistinguishable from cervids experimentally infected with bovine spongiform encephalopathy (BSE).

Given this, if CWD was to be introduced into countries with BSE such as GB, for example, infected deer populations would need to be tested to differentiate if they were infected with CWD or BSE to minimise the risk of BSE entering the human food-chain via affected venison.

snip...

The rate of transmission of CWD has been reported to be as high as 30% and can approach 100% among captive animals in endemic areas (Safar et al., 2008).

snip...

In summary, in endemic areas, there is a medium probability that the soil and surrounding environment is contaminated with CWD prions and in a bioavailable form. In rural areas where CWD has not been reported and deer are present, there is a greater than negligible risk the soil is contaminated with CWD prion.

snip...

In summary, given the volume of tourists, hunters and servicemen moving between GB and North America, the probability of at least one person travelling to/from a CWD affected area and, in doing so, contaminating their clothing, footwear and/or equipment prior to arriving in GB is greater than negligible. For deer hunters, specifically, the risk is likely to be greater given the increased contact with deer and their environment. However, there is significant uncertainty associated with these estimates.

snip...

Therefore, it is considered that farmed and park deer may have a higher probability of exposure to CWD transferred to the environment than wild deer given the restricted habitat range and higher frequency of contact with tourists and returning GB residents.

Submitted to: Prion Publication Type: Abstract Only Publication Acceptance Date: 3/15/2017 Publication Date: N/A Citation: N/A Interpretive Summary:

Technical Abstract: Aims: Chronic wasting disease (CWD) is a naturally-occurring, fatal neurodegenerative disease of cervids. We previously demonstrated that disease-associated prion protein (PrPSc) can be detected in the brain and retina from pigs challenged intracranially or orally with the CWD agent. In that study, neurological signs consistent with prion disease were observed only in one pig: an intracranially challenged pig that was euthanized at 64 months post-challenge. The purpose of this study was to use an antigen-capture immunoassay (EIA) and real-time quaking-induced conversion (QuIC) to determine whether PrPSc is present in lymphoid tissues from pigs challenged with the CWD agent.

Methods: At two months of age, crossbred pigs were challenged by the intracranial route (n=20), oral route (n=19), or were left unchallenged (n=9). At approximately 6 months of age, the time at which commercial pigs reach market weight, half of the pigs in each group were culled (<6 challenge="" groups="" month="" pigs="" remaining="" the="">6 month challenge groups) were allowed to incubate for up to 73 months post challenge (mpc). The retropharyngeal lymph node (RPLN) was screened for the presence of PrPSc by EIA and immunohistochemistry (IHC). The RPLN, palatine tonsil, and mesenteric lymph node (MLN) from 6-7 pigs per challenge group were also tested using EIA and QuIC.

Results: PrPSc was not detected by EIA and IHC in any RPLNs. All tonsils and MLNs were negative by IHC, though the MLN from one pig in the oral <6 5="" 6="" at="" by="" detected="" eia.="" examined="" group="" in="" intracranial="" least="" lymphoid="" month="" months="" of="" one="" pigs="" positive="" prpsc="" quic="" the="" tissues="" was="">6 months group, 5/6 pigs in the oral <6 4="" and="" group="" months="" oral="">6 months group. Overall, the MLN was positive in 14/19 (74%) of samples examined, the RPLN in 8/18 (44%), and the tonsil in 10/25 (40%). Conclusions:

This study demonstrates that PrPSc accumulates in lymphoid tissues from pigs challenged intracranially or orally with the CWD agent, and can be detected as early as 4 months after challenge.

CWD-infected pigs rarely develop clinical disease and if they do, they do so after a long incubation period. This raises the possibility that CWD-infected pigs could shed prions into their environment long before they develop clinical disease.

Furthermore, lymphoid tissues from CWD-infected pigs could present a potential source of CWD infectivity in the animal and human food chains.

EXPERIMENTAL PORCINE SPONGIFORM ENCEPHALOPATHY

While this clearly is a cause for concern we should not jump to the conclusion that this means that pigs will necessarily be infected by bone and meat meal fed by the oral route as is the case with cattle. ...



we cannot rule out the possibility that unrecognised subclinical spongiform encephalopathy could be present in British pigs though there is no evidence for this: only with parenteral/implantable pharmaceuticals/devices is the theoretical risk to humans of sufficient concern to consider any action.


 
Our records show that while some use is made of porcine materials in medicinal products, the only products which would appear to be in a hypothetically ''higher risk'' area are the adrenocorticotrophic hormone for which the source material comes from outside the United Kingdom, namely America China Sweden France and Germany. The products are manufactured by Ferring and Armour. A further product, ''Zenoderm Corium implant'' manufactured by Ethicon, makes use of porcine skin - which is not considered to be a ''high risk'' tissue, but one of its uses is described in the data sheet as ''in dural replacement''. This product is sourced from the United Kingdom.....

cattle are highly susceptible to white-tailed deer CWD and mule deer CWD

***In contrast, cattle are highly susceptible to white-tailed deer CWD and mule deer CWD in experimental conditions but no natural CWD infections in cattle have been reported (Sigurdson, 2008; Hamir et al., 2006). It is not known how susceptible humans are to CWD but given that the prion can be present in muscle, it is likely that humans have been exposed to the agent via consumption of venison (Sigurdson, 2008). Initial experimental research, however, suggests that human susceptibility to CWD is low and there may be a robust species barrier for CWD transmission to humans (Sigurdson, 2008). It is apparent, though, that CWD is affecting wild and farmed cervid populations in endemic areas with some deer populations decreasing as a result.

White-tailed deer are susceptible to the agent of sheep scrapie by intracerebral inoculation

snip...

It is unlikely that CWD will be eradicated from free-ranging cervids, and the disease is likely to continue to spread geographically [10]. However, the potential that white-tailed deer may be susceptible to sheep scrapie by a natural route presents an additional confounding factor to halting the spread of CWD. This leads to the additional speculations that

1) infected deer could serve as a reservoir to infect sheep with scrapie offering challenges to scrapie eradication efforts and

2) CWD spread need not remain geographically confined to current endemic areas, but could occur anywhere that sheep with scrapie and susceptible cervids cohabitate.

This work demonstrates for the first time that white-tailed deer are susceptible to sheep scrapie by intracerebral inoculation with a high attack rate and that the disease that results has similarities to CWD. These experiments will be repeated with a more natural route of inoculation to determine the likelihood of the potential transmission of sheep scrapie to white-tailed deer. If scrapie were to occur in white-tailed deer, results of this study indicate that it would be detected as a TSE, but may be difficult to differentiate from CWD without in-depth biochemical analysis.

PO-039: A comparison of scrapie and chronic wasting disease in white-tailed deer

Justin Greenlee, Jodi Smith, Eric Nicholson US Dept. Agriculture; Agricultural Research Service, National Animal Disease Center; Ames, IA USA

snip...

The results of this study suggest that there are many similarities in the manifestation of CWD and scrapie in WTD after IC inoculation including early and widespread presence of PrPSc in lymphoid tissues, clinical signs of depression and weight loss progressing to wasting, and an incubation time of 21-23 months. Moreover, western blots (WB) done on brain material from the obex region have a molecular profile similar to CWD and distinct from tissues of the cerebrum or the scrapie inoculum. However, results of microscopic and IHC examination indicate that there are differences between the lesions expected in CWD and those that occur in deer with scrapie: amyloid plaques were not noted in any sections of brain examined from these deer and the pattern of immunoreactivity by IHC was diffuse rather than plaque-like.

*** After a natural route of exposure, 100% of WTD were susceptible to scrapie.

Deer developed clinical signs of wasting and mental depression and were necropsied from 28 to 33 months PI. Tissues from these deer were positive for PrPSc by IHC and WB. Similar to IC inoculated deer, samples from these deer exhibited two different molecular profiles: samples from obex resembled CWD whereas those from cerebrum were similar to the original scrapie inoculum. On further examination by WB using a panel of antibodies, the tissues from deer with scrapie exhibit properties differing from tissues either from sheep with scrapie or WTD with CWD. Samples from WTD with CWD or sheep with scrapie are strongly immunoreactive when probed with mAb P4, however, samples from WTD with scrapie are only weakly immunoreactive. In contrast, when probed with mAb’s 6H4 or SAF 84, samples from sheep with scrapie and WTD with CWD are weakly immunoreactive and samples from WTD with scrapie are strongly positive. This work demonstrates that WTD are highly susceptible to sheep scrapie, but on first passage, scrapie in WTD is differentiable from CWD.

Using in vitro Prion replication for high sensitive detection of prions and prionlike proteins and for understanding mechanisms of transmission. Claudio Soto Mitchell Center for Alzheimer's diseases and related Brain disorders, Department of Neurology, University of Texas Medical School at Houston. Prion and prion-like proteins are misfolded protein aggregates with the ability to selfpropagate to spread disease between cells, organs and in some cases across individuals. I n T r a n s m i s s i b l e s p o n g i f o r m encephalopathies (TSEs), prions are mostly composed by a misfolded form of the prion protein (PrPSc), which propagates by transmitting its misfolding to the normal prion protein (PrPC). The availability of a procedure to replicate prions in the laboratory may be important to study the mechanism of prion and prion-like spreading and to develop high sensitive detection of small quantities of misfolded proteins in biological fluids, tissues and environmental samples. Protein Misfolding Cyclic Amplification (PMCA) is a simple, fast and efficient methodology to mimic prion replication in the test tube. PMCA is a platform technology that may enable amplification of any prion-like misfolded protein aggregating through a seeding/nucleation process. In TSEs, PMCA is able to detect the equivalent of one single molecule of infectious PrPSc and propagate prions that maintain high infectivity, strain properties and species specificity. Using PMCA we have been able to detect PrPSc in blood and urine of experimentally infected animals and humans affected by vCJD with high sensitivity and specificity. Recently, we have expanded the principles of PMCA to amplify amyloid-beta (Aβ) and alphasynuclein (α-syn) aggregates implicated in Alzheimer's and Parkinson's diseases, respectively. Experiments are ongoing to study the utility of this technology to detect Aβ and α-syn aggregates in samples of CSF and blood from patients affected by these diseases.

=========================

***Recently, we have been using PMCA to study the role of environmental prion contamination on the horizontal spreading of TSEs. These experiments have focused on the study of the interaction of prions with plants and environmentally relevant surfaces. Our results show that plants (both leaves and roots) bind tightly to prions present in brain extracts and excreta (urine and feces) and retain even small quantities of PrPSc for long periods of time. Strikingly, ingestion of prioncontaminated leaves and roots produced disease with a 100% attack rate and an incubation period not substantially longer than feeding animals directly with scrapie brain homogenate. Furthermore, plants can uptake prions from contaminated soil and transport them to different parts of the plant tissue (stem and leaves). Similarly, prions bind tightly to a variety of environmentally relevant surfaces, including stones, wood, metals, plastic, glass, cement, etc. Prion contaminated surfaces efficiently transmit prion disease when these materials were directly injected into the brain of animals and strikingly when the contaminated surfaces were just placed in the animal cage. These findings demonstrate that environmental materials can efficiently bind infectious prions and act as carriers of infectivity, suggesting that they may play an important role in the horizontal transmission of the disease.

========================

Since its invention 13 years ago, PMCA has helped to answer fundamental questions of prion propagation and has broad applications in research areas including the food industry, blood bank safety and human and veterinary disease diagnosis.

*** Temporal patterns of chronic wasting disease prion excretion in three cervid species ***


Discussion Classical scrapie is an environmentally transmissible disease because it has been reported in naïve, supposedly previously unexposed sheep placed in pastures formerly occupied by scrapie-infected sheep (4, 19, 20). 

Although the vector for disease transmission is not known, soil is likely to be an important reservoir for prions (2) where – based on studies in rodents – prions can adhere to minerals as a biologically active form (21) and remain infectious for more than 2 years (22). 

Similarly, chronic wasting disease (CWD) has re-occurred in mule deer housed in paddocks used by infected deer 2 years earlier, which was assumed to be through foraging and soil consumption (23). 

Our study suggested that the risk of acquiring scrapie infection was greater through exposure to contaminated wooden, plastic, and metal surfaces via water or food troughs, fencing, and hurdles than through grazing. 

Drinking from a water trough used by the scrapie flock was sufficient to cause infection in sheep in a clean building. 

Exposure to fences and other objects used for rubbing also led to infection, which supported the hypothesis that skin may be a vector for disease transmission (9). 

The risk of these objects to cause infection was further demonstrated when 87% of 23 sheep presented with PrPSc in lymphoid tissue after grazing on one of the paddocks, which contained metal hurdles, a metal lamb creep and a water trough in contact with the scrapie flock up to 8 weeks earlier, whereas no infection had been demonstrated previously in sheep grazing on this paddock, when equipped with new fencing and field furniture. 

When the contaminated furniture and fencing were removed, the infection rate dropped significantly to 8% of 12 sheep, with soil of the paddock as the most likely source of infection caused by shedding of prions from the scrapie-infected sheep in this paddock up to a week earlier. 

This study also indicated that the level of contamination of field furniture sufficient to cause infection was dependent on two factors: stage of incubation period and time of last use by scrapie-infected sheep. 

Drinking from a water trough that had been used by scrapie sheep in the predominantly pre-clinical phase did not appear to cause infection, whereas infection was shown in sheep drinking from the water trough used by scrapie sheep in the later stage of the disease. 

It is possible that contamination occurred through shedding of prions in saliva, which may have contaminated the surface of the water trough and subsequently the water when it was refilled. 

Contamination appeared to be sufficient to cause infection only if the trough was in contact with sheep that included clinical cases. 

Indeed, there is an increased risk of bodily fluid infectivity with disease progression in scrapie (24) and CWD (25) based on PrPSc detection by sPMCA. 

Although ultraviolet light and heat under natural conditions do not inactivate prions (26), furniture in contact with the scrapie flock, which was assumed to be sufficiently contaminated to cause infection, did not act as vector for disease if not used for 18 months, which suggest that the weathering process alone was sufficient to inactivate prions. 

PrPSc detection by sPMCA is increasingly used as a surrogate for infectivity measurements by bioassay in sheep or mice. 

In this reported study, however, the levels of PrPSc present in the environment were below the limit of detection of the sPMCA method, yet were still sufficient to cause infection of in-contact animals. 

In the present study, the outdoor objects were removed from the infected flock 8 weeks prior to sampling and were positive by sPMCA at very low levels (2 out of 37 reactions). 

As this sPMCA assay also yielded 2 positive reactions out of 139 in samples from the scrapie-free farm, the sPMCA assay could not detect PrPSc on any of the objects above the background of the assay. 

False positive reactions with sPMCA at a low frequency associated with de novo formation of infectious prions have been reported (27, 28). 

This is in contrast to our previous study where we demonstrated that outdoor objects that had been in contact with the scrapie-infected flock up to 20 days prior to sampling harbored PrPSc that was detectable by sPMCA analysis [4 out of 15 reactions (12)] and was significantly more positive by the assay compared to analogous samples from the scrapie-free farm. 

This discrepancy could be due to the use of a different sPMCA substrate between the studies that may alter the efficiency of amplification of the environmental PrPSc. 

In addition, the present study had a longer timeframe between the objects being in contact with the infected flock and sampling, which may affect the levels of extractable PrPSc. 

Alternatively, there may be potentially patchy contamination of this furniture with PrPSc, which may have been missed by swabbing. 

The failure of sPMCA to detect CWD-associated PrP in saliva from clinically affected deer despite confirmation of infectivity in saliva-inoculated transgenic mice was associated with as yet unidentified inhibitors in saliva (29), and it is possible that the sensitivity of sPMCA is affected by other substances in the tested material. 

In addition, sampling of amplifiable PrPSc and subsequent detection by sPMCA may be more difficult from furniture exposed to weather, which is supported by the observation that PrPSc was detected by sPMCA more frequently in indoor than outdoor furniture (12). 

A recent experimental study has demonstrated that repeated cycles of drying and wetting of prion-contaminated soil, equivalent to what is expected under natural weathering conditions, could reduce PMCA amplification efficiency and extend the incubation period in hamsters inoculated with soil samples (30). 

This seems to apply also to this study even though the reduction in infectivity was more dramatic in the sPMCA assays than in the sheep model. 

Sheep were not kept until clinical end-point, which would have enabled us to compare incubation periods, but the lack of infection in sheep exposed to furniture that had not been in contact with scrapie sheep for a longer time period supports the hypothesis that prion degradation and subsequent loss of infectivity occurs even under natural conditions. 

In conclusion, the results in the current study indicate that removal of furniture that had been in contact with scrapie-infected animals should be recommended, particularly since cleaning and decontamination may not effectively remove scrapie infectivity (31), even though infectivity declines considerably if the pasture and the field furniture have not been in contact with scrapie-infected sheep for several months. As sPMCA failed to detect PrPSc in furniture that was subjected to weathering, even though exposure led to infection in sheep, this method may not always be reliable in predicting the risk of scrapie infection through environmental contamination. 

These results suggest that the VRQ/VRQ sheep model may be more sensitive than sPMCA for the detection of environmentally associated scrapie, and suggest that extremely low levels of scrapie contamination are able to cause infection in susceptible sheep genotypes.

Abstract

Environmental reservoirs are important to infectious disease transmission and persistence, but empirical analyses are relatively few. The natural environment is a reservoir for prions that cause chronic wasting disease (CWD) and influences the risk of transmission to susceptible cervids. Soil is one environmental component demonstrated to affect prion infectivity and persistence. Here we provide the first landscape predictive model for CWD based solely on soil characteristics. We built a boosted regression tree model to predict the probability of the persistent presence of CWD in a region of northern Illinois using CWD surveillance in deer and soils data. We evaluated the outcome for possible pathways by which soil characteristics may increase the probability of CWD transmission via environmental contamination. Soil clay content and pH were the most important predictive soil characteristics of the persistent presence of CWD. The results suggest that exposure to prions in the environment is greater where percent clay is less than 18% and soil pH is greater than 6.6. These characteristics could alter availability of prions immobilized in soil and contribute to the environmental risk factors involved in the epidemiological complexity of CWD infection in natural populations of white-tailed deer.


Oral Transmissibility of Prion Disease Is Enhanced by Binding to Soil Particles

Author Summary

Transmissible spongiform encephalopathies (TSEs) are a group of incurable neurological diseases likely caused by a misfolded form of the prion protein. TSEs include scrapie in sheep, bovine spongiform encephalopathy (‘‘mad cow’’ disease) in cattle, chronic wasting disease in deer and elk, and Creutzfeldt-Jakob disease in humans. Scrapie and chronic wasting disease are unique among TSEs because they can be transmitted between animals, and the disease agents appear to persist in environments previously inhabited by infected animals. Soil has been hypothesized to act as a reservoir of infectivity and to bind the infectious agent. In the current study, we orally dosed experimental animals with a common clay mineral, montmorillonite, or whole soils laden with infectious prions, and compared the transmissibility to unbound agent. We found that prions bound to montmorillonite and whole soils remained orally infectious, and, in most cases, increased the oral transmission of disease compared to the unbound agent. The results presented in this study suggest that soil may contribute to environmental spread of TSEs by increasing the transmissibility of small amounts of infectious agent in the environment.

Durkin: Stop private deer industry from trucking CWD across state 

Patrick Durkin, For USA TODAY NETWORK-Wisconsin Published 10:13 a.m. CT Feb. 16, 2018 

A Waupaca County captive-deer shooting preserve that discovered its first two cases of chronic wasting disease in October found 10 more CWD cases last fall, with 11 of the deer coming from a breeding facility in Iowa County — Wisconsin’s most infected county.

Hunt’s End Deer Ranch near Ogdensburg is one of 376 fenced deer farms in Wisconsin, according to the Department of Agriculture, Trade and Consumer Protection. Hunt’s End bought the diseased deer from Windy Ridge Whitetails, a 15-acre, 110-deer breeding facility south of Mineral Point in Iowa County. Of Wisconsin’s 4,175 CWD cases in wild deer, 2,261 (54 percent) are in Iowa County.

Since CWD’s discovery in three wild deer shot during the November 2001 gun season, CWD has been detected on 18 Wisconsin deer farms, of which 11 were “depopulated.” DATCP has identified 242 CWD cases in captive facilities the past 16 years.

The state’s worst site remains the former Buckhorn Flats Game Farm near Almond in Portage County, where 80 deer tested positive for this always-fatal disease from 2002 to 2006. When the U.S. Department of Agriculture shot out the 70-acre pen in January 2006, 60 of the remaining 76 deer carried CWD, a nearly 80 percent infection rate. 

The Department of Natural Resources bought the heavily contaminated site for $465,000 in 2011 and has kept it fenced and deer-free since.

The last time DATCP exterminated a captive herd was November 2015, when it killed 228 deer at Fairchild Whitetails, a 10-acre breeding facility in Eau Claire County, and paid its owner, Richard Vojtik, $298,770 in compensation. Tests revealed 34 of those deer carried CWD (15 percent), but two bucks had escaped earlier. Those bucks roamed five months before being shot and tested. They, too, had CWD.

Both operations were outside the endemic CWD region in southern Wisconsin; Buckhorn Flats by about 60 miles and Fairchild Whitetails by about 120. Wisconsin’s four most active CWD outbreaks on deer farms are north of U.S. 10, and farther away from the endemic region — basically the DNR’s Southern Farmlands district — which had 584 CWD cases 2017-18 and 4,148 since 2001.

Those businesses are:

• Wilderness Whitetails, near Eland in Marathon County: 68 CWD cases, including 43 in 2017-18. DATCP first reported CWD there in December 2013 in a 5-year-old buck shot by a facility client. The operation also found three cases in 2014, nine in 2015 and 12 in 2016. 

The preserve held about 310 deer in its 351-acre pen last summer. Since beginning tests in 2002, the facility tested 373 deer before finding its first case 11 years later.

• Hunt’s End, Waupaca County: 12 cases, all in 2017-18. The owners, Dusty and Mandy Reid, didn’t detect CWD on the 84-acre shooting facility until two 4-year-old bucks tested positive last fall. DATCP announced those cases Oct. 20, and disclosed 10 additional cases in response to my open-records request in January.

Both Oct. 20 bucks originated from Windy Ridge Whitetails. Nine other bucks from Windy Ridge, owned by Steven and Marsh Bertram, tested positive for CWD after being shot by Hunt’s End clients.

Now DATCP records covering the past five years showed Hunt’s End acquired 31 deer from Windy Ridge, which also sent a combined 67 whitetails to nine other Wisconsin deer farms during that period.

Paul McGraw, DATCP’s state veterinarian and administrator in animal health, quarantined three Hunt’s End properties Oct. 20, but let its owners, continue selling hunts because “properly handled dead animals leaving the premises do not pose a disease risk.”

McGraw also quarantined Windy Ridge, but the specifications let the business move more deer to the Waupaca shooting facility. It made two more shipments to Hunt’s End, the last occurring Nov. 13.

• Apple Creek Whitetails, Oconto County: 11 cases. Since discovering CWD in September 2016 in an 18-month-old doe killed inside the facility near Gillett, DATCP has identified 10 more cases, including three in 2017-18. The preserve held about 1,850 deer on 1,363 acres, and tested 466 in 2016. After first testing for CWD in 2009, the business processed 1,192 deer before finding its first case 18 months ago.

• Three Lakes Trophy Ranch, Oneida County: Nine cases. Since discovering CWD in December 2015 in a 3-year-old buck at Three Lakes, DATCP has identified eight more cases, including two in 2017-18. The preserve held about 545 whitetails on 570 acres.

Although the Hunt’s End outbreak traces to Iowa County deer, Windy Ridge Whitetails sent even more deer, 42, to Vojtik’s American Adventures Ranch near Fairchild with no documented problems. DATCP reports no CWD cases there, and Vojtik, who also owned the 10-acre Fairchild Whitetails breeding facility, said he hasn’t bought Windy Ridge deer the past two years.

Vojtik said Wednesday that he and his clients shoot out his enclosure’s herd of about 200 deer each year to reduce CWD risks. And because he’s not in DATCP’s herd-status program, he must only test 50 percent of deer dying there.

Meanwhile, Wilderness Whitetails tests all of its dead deer. It leads the state with 68 CWD cases, even though it has maintained a “closed herd” since opening its Eland facility in 2004, said its owner, Greg Flees, when reached Wednesday. Flees said all deer in the 351-acre facility were born there or came from his family’s Portage County breeding pen, which began in the 1970s and has never had CWD.

Flees said the jump from 12 CWD cases in 2016 to 43 in 2017 is no mystery or surprise. “We shot more deer to lower our densities, so we found more CWD,” he said. He thinks CWD was in the facility’s soils when they enclosed it with an 8-foot-high fence 14 years ago, or it arrived in alfalfa bales brought in for feed.

Perhaps the bigger mystery is why DATCP allows any deer from Iowa County to be shipped anywhere. Windy Ridge Whitetails is one of eight captive-deer facilities in CWD-infected counties — Sauk, Dane, Iowa, Rock, Walworth and Richland — enrolled in DATCP’s herd-status program, which allows deer transfers if facilities follow specified guidelines.

That won’t change soon, either. In a letter Jan. 30 responding to my open records request, Paul Dedinsky, DATCP’s chief legal counsel, wrote, “The Department is not proposing any rule changes to prohibit movement from CWD endemic areas.”

No doubt Wisconsin’s wild deer provide a vast, mostly undocumented pool for spreading CWD, but sick deer can only carry disease as far as they walk. With DATCP’s approval, privately owned deer could spread CWD wherever they’re trucked.

CHRONIC WASTING DISEASE CWD WISCONSIN Almond Deer (Buckhorn Flats) Farm Update DECEMBER 2011

The CWD infection rate was nearly 80%, the highest ever in a North American captive herd. RECOMMENDATION: That the Board approve the purchase of 80 acres of land for $465,000 for the Statewide Wildlife Habitat Program in Portage County and approve the restrictions on public use of the site.

SUMMARY:


captive deer farmers breeders entitlement program, i.e. indemnity program, why?

how many states have $465,000., and can quarantine and purchase there from, each cwd said infected farm, but how many states can afford this for all the cwd infected cervid game ranch type farms, and why do tax payers have to pay for it ???

TEST RESULTS FROM CAPTIVE DEER HERD WITH CHRONIC WASTING DISEASE RELEASED 79.8 percent of the deer tested positive for the disease

DES MOINES – The Iowa Department of Agriculture and Land Stewardship today announced that the test results from the depopulation of a quarantined captive deer herd in north-central Iowa showed that 284 of the 356 deer, or 79.8% of the herd, tested positive for Chronic Wasting Disease (CWD). The owners of the quarantined herd have entered into a fence maintenance agreement with the Iowa Department of Agriculture and Land Stewardship, which requires the owners to maintain the 8’ foot perimeter fence around the herd premises for five years after the depopulation was complete and the premises had been cleaned and disinfected

CWD is a progressive, fatal, degenerative neurological disease of farmed and free-ranging deer, elk, and moose. There is no known treatment or vaccine for CWD. CWD is not a disease that affects humans.

On July 18, 2012, USDA Animal and Plant Health Inspection Service’s (APHIS) National Veterinary Services Lab in Ames, IA confirmed that a male white tail deer harvested from a hunting preserve in southeast IA was positive for CWD. An investigation revealed that this animal had just been introduced into the hunting preserve from the above-referenced captive deer herd in north-central Iowa.

The captive deer herd was immediately quarantined to prevent the spread of CWD. The herd has remained in quarantine until its depopulation on August 25 to 27, 2014.

The Iowa Department of Agriculture and Land Stewardship participated in a joint operation to depopulate the infected herd with USDA Veterinary Services, which was the lead agency, and USDA Wildlife Services.

Federal indemnity funding became available in 2014. USDA APHIS appraised the captive deer herd of 376 animals at that time, which was before depopulation and testing, at $1,354,250. At that time a herd plan was developed with the owners and officials from USDA and the Iowa Department of Agriculture and Land Stewardship.

Once the depopulation was complete and the premises had been cleaned and disinfected, indemnity of $917,100.00 from the USDA has been or will be paid to the owners as compensation for the 356 captive deer depopulated.

The Iowa Department of Agriculture and Land Stewardship operates a voluntary CWD program for farms that sell live animals. Currently 145 Iowa farms participate in the voluntary program. The above-referenced captive deer facility left the voluntary CWD program prior to the discovery of the disease as they had stopped selling live animals. All deer harvested in a hunting preserve must be tested for CWD.

INFORM: Cervid Health and States Indemnity FY 2015

USDA Animal and Plant Health Inspection Service sent this bulletin at 09/19/2014 05:22 PM EDT

Animal and Plant Health Inspection Service (APHIS), Veterinary Services (VS) received a total of $3 million in appropriated funding to support cervid health activities in fiscal year (FY) 2014, and made approximately $1.0 million of this funding available for indemnity of chronic wasting disease (CWD) positive, suspect, and exposed farmed cervids. All of the available FY2014 indemnity funding was used to depopulate three CWD-infected herds. However, several States have asked about the availability of Federal indemnity funds for CWD-exposed animals in the future.

VS plans to offer Federal indemnity for CWD-exposed cervids beginning in FY2015. Briefly, we will prioritize the highest risk CWD-exposed animals for indemnity based on the availability of funding. Any newly reported CWD-positive herds will be considered for indemnity as they are identified, based first on funding availability and secondly on the risk presented by the herd.

We will reassess our fiscal year funding on a quarterly basis so that providing indemnity for exposed animals does not exhaust available funding early in the fiscal year. By taking this fiscally cautious approach, we hope to provide indemnity for positive herds identified later in the fiscal year while removing high-risk animals from the landscape as soon as possible to minimize the risk for disease spread. Further, removal and testing of these exposed animals will provide a better understanding of the disease risk presented by these animals/herds.

VS plans to work with our State and industry stakeholders on the criteria to assess the risk and on the process through which States can request this indemnity. These will be finalized in a VS Guidance Document in the near future. We look forward to working with you to implement this process in the coming year.

Abstract

In classical bovine spongiform encephalopathy (C-BSE), an orally acquired prion disease of cattle, the ileal Peyer’s patch (IPP) represents the main entry port for the BSE agent. In earlier C-BSE pathogenesis studies, cattle at 4–6 months of age were orally challenged, while there are strong indications that the risk of infection is highest in young animals. In the present study, unweaned calves aged 4–6 weeks were orally challenged to determine the earliest time point at which newly formed PrPBSE and BSE infectivity are detectable in the IPP. For this purpose, calves were culled 1 week as well as 2, 4, 6 and 8 months post-infection (mpi) and IPPs were examined for BSE infectivity using a bovine PrP transgenic mouse bioassay, and for PrPBSE by immunohistochemistry (IHC) and protein misfolding cyclic amplification (PMCA) assays. For the first time, BSE prions were detected in the IPP as early as 2 mpi by transgenic mouse bioassay and PMCA and 4 mpi by IHC in the follicular dendritic cells (FDCs) of the IPP follicles. These data indicate that BSE prions propagate in the IPP of unweaned calves within 2 months of oral uptake of the agent.

snip...

In summary, our study demonstrates for the first time PrPBSE (by PMCA) and prion infectivity (by mouse bioassay) in the ileal Peyer’s patch (IPP) of young calves as early as 2 months after infection. From 4 mpi nearly all calves showed PrPBSE positive IPP follicles (by IHC), even with PrPBSE accumulation detectable in FDCs in some animals. Finally, our results confirm the IPP as the early port of entry for the BSE agent and a site of initial propagation of PrPBSE and infectivity during the early pathogenesis of the disease. Therefore, our study supports the recommendation to remove the last four metres of the small intestine (distal ileum) at slaughter, as designated by current legal requirements for countries with a controlled BSE risk status, as an essential measure for consumer and public health protection.

USAHA 2017 RESOLUTIONS

RESOLUTION NUMBER: 23 

APPROVED AS AMENDED SOURCE: COMMITTEE ON WILDLIFE AND CAPTIVE WILDLIFE 

SUBJECT MATTER: Annual Reporting on Chronic Wasting Disease Epidemiological Data 

BACKGROUND INFORMATION: Chronic wasting disease (CWD) has been recognized in wild cervids since the 1980’s. Availability of complete epidemiological information is critical for evaluating the effectiveness of science-based disease control programs. Access to pertinent information from epidemiological investigations across the country in wild populations is imperative to developing success strategies for managing the disease. More comprehensive information is needed on CWD epidemiology in the affected wild populations. Analysis of data from CWD affected populations across the country will improve risk assessment. Comprehensive epidemiological data evaluation may potentially identify factors contributing to the detection of CWD, enhance mitigation strategies to reduce the likelihood of CWD in new populations, and facilitate its earliest detection when it is present. 

RESOLUTION: The United States Animal Health Association (USAHA) requests the United States Department of Agriculture (USDA), Animal and Plant Health Inspection Service, Veterinary Services and other appropriate federal and state agencies to work cooperatively to assemble, analyze, summarize, and make available annually to the Committee on Wildlife and Captive Wildlife at the USAHA meeting all pertinent information from epidemiological investigations of Chronic Wasting Disease (CWD) in cervid populations (including wild, free-ranging, and captive). 

Specific information requested may include: 

1) Compiled CWD testing data from each state to include: 

a) Overall state testing numbers of each susceptible species tested; 

b) Number of CWD positive tests found annually in each state; 

c) Overall state testing in wild populations; 

d) Prevalence of CWD in positive populations; 

e) Population totals for each susceptible species of wild herds in each state; 

f) Demography of positive and negative animals in infected herds; 

g) Results from all tissues that were tested; 

h) Duration of monitoring prior to detection of the first case - including numbers of animals in the herd, numbers tested, and numbers not tested; 

i) Results of trace-forward and trace-back investigations; and 

j) All other pertinent data that will enhance risk assessment of CWD in cervids and identification of effective mitigation measures. 

2) Compiled data should also be posted on the USDA website.

RESOLUTION NUMBER: 21 APPROVED SOURCE: COMMITTEE ON SHEEP, GOATS AND CAMELIDS SUBJECT MATTER: National Scrapie Eradication Program Funding 

BACKGROUND INFORMATION: Due to the success of the cooperative National Scrapie Eradication Program, no new cases of scrapie have been identified in the United States (US) in the past 18 months. There are key components of the program that have been critical to this success and the effort to have the US be recognized internationally as free from scrapie, which would open new markets to US sheep and goat products. Surveillance and traceability are vital to this eradication program. Program use of sheep and goat official tags have demonstrated that official plastic tags are preferred over metal tags for readability and to reduce safety concerns. Funding for tags that are readable, acceptable to producers and efficient for regulators is essential to continue identification compliance and progress of the program. 

RESOLUTION: The United States Animal Health Association urges the United States Secretary of Agriculture to request a congressional appropriation of five million additional dollars of new money to be added to the Equine, Cervid and Small Ruminant health line for the purpose of supporting Small Ruminant Health Programs to complete the eradication of scrapie and assure program success. It is vital that this new funding does not reduce other current United States Department of Agriculture, Animal and Plant Health Inspection Service, Veterinary Services program funding lines.

Blood-derived amyloid-β protein induces Alzheimer’s disease pathologies

Alzheimer’s disease, iatrogenic, and Transmissible Spongiform Encephalopathy TSE Prion disease, that is the question ??? 

>>> The only tenable public line will be that "more research is required’’ <<< 

>>> possibility on a transmissible prion remains open<<< 

O.K., so it’s about 23 years later, so somebody please tell me, when is "more research is required’’ enough time for evaluation ?

[9. Whilst this matter is not at the moment directly concerned with the iatrogenic CJD cases from hgH, there remains a possibility of litigation here, and this presents an added complication. There are also results to be made available shortly (1) concerning a farmer with CJD who had BSE animals, (2) on the possible transmissibility of Alzheimer’s and (3) a CMO letter on prevention of iatrogenic CJD transmission in neurosurgery, all of which will serve to increase media interest.]

Subject: 1992 IN CONFIDENCE TRANSMISSION OF ALZHEIMER TYPE PLAQUES TO PRIMATES POSSIBILITY ON A TRANSMISSIBLE PRION REMAINS OPEN

TRANSMISSION OF ALZHEIMER TYPE PLAQUES TO PRIMATES 

1. Thank you for showing me Diana Dunstan's letter. I am glad that MRC have recognised the public sensitivity of these findings and intend to report them in their proper context. 'This hopefully will avoid misunderstanding and possible distortion by the media to portray the results as having more greater significance than the findings so far justify. 

2. Using a highly unusual route of transmission (intra-cerebral injection) the researchers have demonstrated the transmission of a pathological process from two cases one of severe Alzheimer's disease the other of Gerstmann-Straussler disease to marmosets. However they have not demonstrated the transmission of either clinical condition as the "animals were behaving normally when killed". As the report emphasises the unanswered question is whether the disease condition would have revealed itself if the marmosets had lived longer. They are planning further research to see if the conditions, as opposed to the partial pathological process, is transmissible. what are the implications for public health? 

3. The route 'of transmission is very specific and in the natural state of things highly unusual. However it could be argued that the results reveal a potential risk, in that brain tissue from these two patients has been shown to transmit a pathological process. Should therefore brain tissue from such cases be regarded as potentially infective? Pathologists, morticians, neuro surgeons and those assisting at neuro surgical procedures and others coming into contact with "raw" human brain tissue could in theory be at risk. 

However, on a priori grounds given the highly specific route of transmission in these experiments that risk must be negligible if the usual precautions for handling brain tissue are observed. 1 

92/11.4/1.1 

BSE101/1 0137 4. 

The other dimension to consider is the public reaction. To some extent the GSS case demonstrates little more than the transmission of BSE to a pig by intra-cerebral injection. If other prion diseases can be transmitted in this way it is little surprise that some pathological findings observed in GSS were also transmissible to a marmoset. But the transmission of features of Alzheimer's pathology is a different matter, given the much greater frequency of this disease and raises the unanswered question whether some cases are the result of a transmissible prion. 

The only tenable public line will be that "more research is required’’ before that hypothesis could be evaluated. The possibility on a transmissible prion remains open. In the meantime MRC needs carefully to consider the range and sequence of studies needed to follow through from the preliminary observations in these two cases. Not a particularly comfortable message, but until we know more about the causation of Alzheimer's disease the total reassurance is not practical.

Alzheimer's disease

let's not forget the elephant in the room. curing Alzheimer's would be a great and wonderful thing, but for starters, why not start with the obvious, lets prove the cause or causes, and then start to stop that. think iatrogenic, friendly fire, or the pass it forward mode of transmission. think medical, surgical, dental, tissue, blood, related transmission. think transmissible spongiform encephalopathy aka tse prion disease aka mad cow type disease...

Alzheimer's disease and transmissible virus dementia (Creutzfeldt-Jakob disease). 

Brown P, Salazar AM, Gibbs CJ Jr, Gajdusek DC. 

Abstract 

Ample justification exists on clinical, pathologic, and biologic grounds for considering a similar pathogenesis for AD and the spongiform virus encephalopathies. However, the crux of the comparison rests squarely on results of attempts to transmit AD to experimental animals, and these results have not as yet validated a common etiology. Investigations of the biologic similarities between AD and the spongiform virus encephalopathies proceed in several laboratories, and our own observation of inoculated animals will be continued in the hope that incubation periods for AD may be even longer than those of CJD.

*** Effect of heating on the stability of amyloid A (AA) fibrils and the intra- and cross-species transmission of AA amyloidosis 

Abstract 

Amyloid A (AA) amyloidosis is a protein misfolding disease characterized by extracellular deposition of AA fibrils. AA fibrils are found in several tissues from food animals with AA amyloidosis. For hygienic purposes, heating is widely used to inactivate microbes in food, but it is uncertain whether heating is sufficient to inactivate AA fibrils and prevent intra- or cross-species transmission. We examined the effect of heating (at 60 °C or 100 °C) and autoclaving (at 121 °C or 135 °C) on murine and bovine AA fibrils using Western blot analysis, transmission electron microscopy (TEM), and mouse model transmission experiments. TEM revealed that a mixture of AA fibrils and amorphous aggregates appeared after heating at 100 °C, whereas autoclaving at 135 °C produced large amorphous aggregates. AA fibrils retained antigen specificity in Western blot analysis when heated at 100 °C or autoclaved at 121 °C, but not when autoclaved at 135 °C. Transmissible pathogenicity of murine and bovine AA fibrils subjected to heating (at 60 °C or 100 °C) was significantly stimulated and resulted in amyloid deposition in mice. Autoclaving of murine AA fibrils at 121 °C or 135 °C significantly decreased amyloid deposition. Moreover, amyloid deposition in mice injected with murine AA fibrils was more severe than that in mice injected with bovine AA fibrils. Bovine AA fibrils autoclaved at 121 °C or 135 °C did not induce amyloid deposition in mice. These results suggest that AA fibrils are relatively heat stable and that similar to prions, autoclaving at 135 °C is required to destroy the pathogenicity of AA fibrils. These findings may contribute to the prevention of AA fibril transmission through food materials to different animals and especially to humans.
