CWD, GAME FARMS, urine, feces, soil, lichens, and banned mad cow protein feed CUSTOM MADE for deer and elk

CWD, GAME FARMS, urine, feces, soil, lichens, and banned mad cow protein feed CUSTOM MADE for deer and elk



Greetings QDMA et al,


some old history about game farms and cwd below, and then, what about game farms and mad cow protein feed for those big bucks $

what about tainted land and soil content ?

urine, feces ?

lichens ?


for those interested, a review of sorts. ...tss



Nebraska Dept of Agriculture and Game and Parks

On April 9, 1998, chronic wasting disease (CWD) was diagnosed in a captive elk in Nebraska.� This discovery follows the confirmation of CWD in two captive elk herds in South Dakota earlier this year.� The Nebraska elk was a 4 1/2-year old male that was among a privately owned herd of approximately 150 elk.� The health of the animal had deteriorated for about 2 months before it died.� Confirmation of CWD was made by the USDA's National Veterinary Services Laboratories in Ames, Iowa. The case history revealed that the affected elk was born on a farm on the Western Slope of the Rocky Mountains in Colorado, but it was on two additional Colorado farms before it arrived in Nebraska at 2 to 2 1/2 years of age.� One of the Colorado premises was in the known CWD-endemic region along the Eastern Slope of the Rocky Mountains in northcentral Colorado.

The Nebraska State Veterinarian's Office has quarantined the affected herd, and a hold order was placed on two additional herds in Nebraska that received animals from the affected herd.� It also has been determined that elk farmers in four states (IA, IL, TX, WI) have received elk from the infected herd, and these states were notified by the Nebraska Bureau of Animal Industry.� Additional tracing may be forthcoming because elk from the affected herd were sold through two auctions in Colorado and Missouri.� A CWD Working Group is being formed to develop Voluntary CWD Management Guidelines.� The first goals of the Nebraska Bureau of Animal Industry are:� (1) to implement a policy requiring disease reporting of animals over 16 months of age; (2) to require identification of individual animals and reporting change of ownership; and (3) to establish a data base to monitor change of ownership.

South Dakota has taken legislative action to create a CWD control program for captive cervids.� Their program calls for a 5-year quarantine with monitoring of all affected, adjacent, or exposed captive cervid herds.� Monitored herds that maintain clean status are given certificates at annual milestones for years 1 through 4 and are designated "Certified CWD Cervid Herd" after 5 years of negative surveillance.� The Cervid CWD Surveillance Identification Program includes required examination of brain tissue from all dead cervids 18 months or older, including deaths by slaughter, hunting, illness, and injury.� The South Dakota State Veterinarian has forwarded the description of his State's program to the United States Animal Health Association along with the suggestion that it should be considered as a "starting place" for developing a Model CWD Control Program.� Persons interested in this document can obtain a copy from Dr. Sam Holland, South Dakota State Veterinarian, SD Animal Industry Board, 411 South Fort Street, Pierre, South Dakota 57501-4503.�

Bad news on game farm elk Dr. Holland, South Dakota State Veterinarian 20 Dec 98 news release

Some initial SD data released by Dr. Holland, SD State Veterinarian was verified with two of his colleagues.

There are 39 game farm elk in South Dakota with confirmed chronic wasting disease in 1998, out of 179 tested (22%).

There are 4 or 5 herds involved - all are from game farm animals, none are from the fall hunt. The total number of elk studied is not yet available for wild elk. Two white-tail deer are also affected, also captive animals.

Elk disease prompts protective quarantine of Philipsburg, Hardin game farms Tue, 23 Jun 1998 (AP)


HELENA- A debilitating disease that showed up in an elk transported from a Montana game farm to Oklahoma has prompted a protective quarantine at two game farms, State Veterinarian Arnold Gertonson said Monday. One is the Kesler Game Farm near Philipsburg, where the elk was sold, and the other is near Hardin where other Kesler elk have been shipped, Gertonson said.

The infected elk was shipped two years ago, and Gertonson said it is unknown if the fatal disease was present in the elk then. "The disease has a long incubation of unknown duration," Gertonson said of chronic wasting disease. It causes deer and elk to waste away and die.

"We are taking the actions necessary at this time to protect the game farms and wild herds," Gertonson said. Gertonson said the only way to diagnose the disease is through an autopsy. He has not yet decided if any of the game farm animals in Philipsburg or Hardin will be killed for testing.

"We want to work with the game farmers as far as the economic effect, but will do what we need to protect the animals," Gertonson said. The first case in a game farm elk was identified in last December in South Dakota. Cases in wild deer were first found in Colorado in 1981 and it has since spread to southeast Wyoming.

The disease is always fatal to the animal, according to Karen Zackheim of the Department of Fish, Wildlife and Parks, but is not believed to pose a threat to humans. [This is an inaccurate and irresponsible statement, very similar to those made by MAFF in early days of BSE -- webmaster] .

A study of elk in Yellowstone County area was performed two years ago and the disease was not found, Zackheim said. [No such study has been published; the number of animals tested is unknown. It may be necessary to re-examine elk brains using newer antibody techniques. -- webmaster]

She said that area was studied because it is along a natural migration route to the infected southeastern Wyoming herd. "I really feel we do not have it in the wild in Montana," Zackheim said.

The Department of Livestock has notified other states where animals from the Kesler farm were shipped. Gertonson said the department learned of the situation late last week but is working as quickly as possible to determine if the disease is present in Montana.

Where all has CWD been found?

18 Mar 98 webmaster One of the oddest aspects of all the scientific papers on CWD is the tremendous reluctance to give the names, dates, locations, and operators of affected state fish and game and university facilities. This makes it very difficult to map where and when the disease has been seen to occur and whether there are independent foci of infection beyond Ft. Colliins/Wheatland. It is hard to believe that expert facilities do not maintain a permanent tracking record for the health and disposition of each and every individual animal. Given the failure of the two eradication schemes, this secrecy makes tracking and confinement of the disease all that much harder, which is in no one's best interest.

White blood cells, marrow, and peripheral neurons are known to be infectious (but low titre compared to CNS) in scrapie, BSE, TME, and CJD; no data is available on CWD titre by tissue type. Low titre means the disease would start amplifying but spongiform changes might be slow relative to normal life span, ie it dies of something else before becoming clinical. Animals can be highly infectious a year or more before displaying symptoms.

The following statement, while on the cautious side, is certainly consistent with current medical understanding of spongiform encephalopathies and the precautionary principle:

Val Geist, former head of the University of Calgary's environmental science department, said even the antlers are capable of carrying the disease because they contain neurological tissue including blood vessels and nerve endings. "If it (TSE) is somewhere in the tissue, I certainly wouldn't ingest any of the tissue."

There are now at least 5 known captive research facilities and at least 3 zoos and 5 game farms involved in CWD, all traceable if you want to shipments of animals out of Ft. Collins. These are:

South Dakota program for cwd in captive elk works well United States Animal Health Association (703) 451-3954 For immediate release:Contact - Larry Mark

MINNEAPOLIS, Minn., Oct. 7, 1998 -- A model program for the containment and eradication of chronic wasting disease (CWD) in captive elk herds was developed and carried out in South Dakota last year in response to the diagnosis of this disease in December 1997 in a captive elk herd in South Dakota. Dr. Sam Holland, South Dakota State Veterinarian, reviewed for the USAHA committee on captive wildlife and alternative livestock a program that was put together in a short period of time and was highly successful. Dr. Holland noted that the occurrence of CWD was treated as an animal health emergency and that great pains were taken to involve all people with a stake in the issue in developing a way to deal with the disease. The group consensus was that a mandatory control program needed to be enacted with official tests and movement criteria.

To date in South Dakota, there have been three elk herds with confirmed CWD and five others that were exposed to the affected herds. The latter have been quarantined for from one to five years. The source elk herd had 30 free-ranging white-tailed deer on the property but not in the same pasture. These 30 deer were harvested and one was found positive for CWD. A surveillance program of free-ranging wildlife has been developed that includes examination of deer and elk killed by hunters....

I expected TSE to appear on commercial elk ranches after it had appeard in a Canadian zoo. When the Saskatchewan case was reported, it was claimed to be an anomaly by the Agriculture Canada PR spokesmen.

Sorry to read that there are now, a year or so later, more TSE cases on game ranches. I am aware that TSE cases in free-living elk and deer in Colorado do coincide with range lands on which scrapie was recorded.

What is fed to captive deer and elk at these game farms?

what Canadian laws and regulations apply amd are there compliance visits?

how many of these game farms/animals are there?

what rules apply to trans-shipment (especially back and forth across borders)?

what sort of records are kept on individual animals?

is there a necropsy program on 'downer' animals? l Dr. Ted Leighton responds: Most of your questions are more appropriate for me to answer than for Dr. Clarke. Health Canada has a broadening program in zoonotic disease surveillance but much of it is currently under development and re-definition. Most of your questions are about CWD in wildlife and in game farmed animals.

Trace-back to origin for the one CWD-positive elk detected in Canada was not possible beyond the last farm of origin prior to importation. This is becaise of a lack of an animal identification and movement registration program for game farmed elk in the USA at the time. There has not been a case of CWD in mule deer on Canadian game farms. The case was at the Toronto zoo. It is thought that the disease originated from the Colorado-Wyoming focus through importation from a captive herd subsequently found to have the disease.


http://www.mad-cow.org/cwd_cattle.html#Canada






*** Spraker suggested an interesting explanation for the occurrence of CWD. The deer pens at the Foot Hills Campus were built some 30-40 years ago by a Dr. Bob Davis. At or abut that time, allegedly, some scrapie work was conducted at this site. When deer were introduced to the pens they occupied ground that had previously been occupied by sheep.

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


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 17 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.

Detection of Environmentally Associated PrPSc on a Farm with Endemic Scrapie

Gough3 1ADAS-UK LTD; Department of Biology; University of Leicester; Leicester, UK; 2Veterinary Laboratories Agency; Surry, KT UK; 3Department of Veterinary Medicine and Science; University of Nottingham; Sutton Bonington, Loughborough UK

Key words: scrapie, evironmental persistence, sPMCA

Ovine scrapie shows considerable horizontal transmission, yet the routes of transmission and specifically the role of fomites in transmission remain poorly defined. Here we present biochemical data demonstrating that on a scrapie-affected sheep farm, scrapie prion contamination is widespread. It was anticipated at the outset that if prions contaminate the environment that they would be there at extremely low levels, as such the most sensitive method available for the detection of PrPSc, serial Protein Misfolding Cyclic Amplification (sPMCA), was used in this study. We investigated the distribution of environmental scrapie prions by applying ovine sPMCA to samples taken from a range of surfaces that were accessible to animals and could be collected by use of a wetted foam swab. Prion was amplified by sPMCA from a number of these environmental swab samples including those taken from metal, plastic and wooden surfaces, both in the indoor and outdoor environment. At the time of sampling there had been no sheep contact with these areas for at least 20 days prior to sampling indicating that prions persist for at least this duration in the environment. These data implicate inanimate objects as environmental reservoirs of prion infectivity which are likely to contribute to disease transmission.

now, I can’t say who has bought up all the mad cow protein feed, but a heck of a lot of it has been fed out, post partial, voluntary, mad cow feed ban.



could part of the CWD be caused by feeding banned mad cow protein (cows, deer, elk, sheep, goats, dogs, cats, and sometimes the circus elephant) was/is in feed for animals, for human and animal consumption.

is it the deer farmers and ranchers using the mad cow protein for those big bucks, or is it the hunters $ only ones I ever heard of using it was the farmers and ranchers. but some hunters might be using cattle feed in feed plots. which brings up another nasty topic, i.e. baiting and feeding, food plots vs apple orchids, or piles of beets, corn, etc., natural vs man made, etc. I guess that’s for another topic, but a factor of CWD control, because I don’t think we can eradicate it now. mad cow is out of the barn, like the mad deer and elk. sad, sad, sad $

they implemented something, then forgot to enforce it $$$$$

another fine example letter. this one will floor you. 'Jimmy crack corn, and they don't care' no big deal, just flush those mixers with corn, then feed the corn to the deer. NOooooo problem.

April 9, 2001 WARNING LETTER

01-PHI-12 CERTIFIED MAIL RETURN RECEIPT REQUESTED

Brian J. Raymond, Owner Sandy Lake Mills 26 Mill Street P.O. Box 117 Sandy Lake, PA 16145 PHILADELPHIA DISTRICT

Tel: 215-597-4390

Dear Mr. Raymond:

Food and Drug Administration Investigator Gregory E. Beichner conducted an inspection of your animal feed manufacturing operation, located in Sandy Lake, Pennsylvania, on March 23, 2001, and determined that your firm manufactures animal feeds including feeds containing prohibited materials. The inspection found significant deviations from the requirements set forth in Title 21, code of Federal Regulations, part 589.2000 - Animal Proteins Prohibited in Ruminant Feed. The regulation is intended to prevent the establishment and amplification of Bovine Spongiform Encephalopathy (BSE) . Such deviations cause products being manufactured at this facility to be misbranded within the meaning of Section 403(f), of the Federal Food, Drug, and Cosmetic Act (the Act).

Our investigation found failure to label your swine feed with the required cautionary statement "Do Not Feed to cattle or other Ruminants" The FDA suggests that the statement be distinguished by different type-size or color or other means of highlighting the statement so that it is easily noticed by a purchaser.

In addition, we note that you are using approximately 140 pounds of cracked corn to flush your mixer used in the manufacture of animal feeds containing prohibited material. This flushed material is fed to wild game including deer, a ruminant animal. Feed material which may potentially contain prohibited material should not be fed to ruminant animals which may become part of the food chain.

The above is not intended to be an all-inclusive list of deviations from the regulations. As a manufacturer of materials intended for animal feed use, you are responsible for assuring that your overall operation and the products you manufacture and distribute are in compliance with the law. We have enclosed a copy of FDA's Small Entity Compliance Guide to assist you with complying with the regulation... blah, blah, blah...

Subject: DOCKET-- 03D-0186 -- FDA Issues Draft Guidance on Use of Material From Deer and Elk in Animal Feed; Availability

Date: Fri, 16 May 2003 11:47:37 –0500

From: "Terry S. Singeltary Sr." To: fdadockets@oc.fda.gov

Greetings FDA,

i would kindly like to comment on;

Docket 03D-0186

FDA Issues Draft Guidance on Use of Material From Deer and Elk in Animal Feed; Availability

Several factors on this apparent voluntary proposal disturbs me greatly, please allow me to point them out;

1. MY first point is the failure of the partial ruminant-to-ruminant feed ban of 8/4/97. this partial and voluntary feed ban of some ruminant materials being fed back to cattle is terribly flawed. without the _total_ and _mandatory_ ban of all ruminant materials being fed back to ruminants including cattle, sheep, goat, deer, elk and mink, chickens, fish (all farmed animals for human/animal consumption), this half ass measure will fail terribly, as in the past decades...

2. WHAT about sub-clinical TSE in deer and elk? with the recent findings of deer fawns being infected with CWD, how many could possibly be sub-clinically infected. until we have a rapid TSE test to assure us that all deer/elk are free of disease (clinical and sub-clinical), we must ban not only documented CWD infected deer/elk, but healthy ones as well. it this is not done, they system will fail...

3. WE must ban not only CNS (SRMs specified risk materials), but ALL tissues. recent new and old findings support infectivity in the rump or ass muscle. wether it be low or high, accumulation will play a crucial role in TSEs.

4. THERE are and have been for some time many TSEs in the USA. TME in mink, Scrapie in Sheep and Goats, and unidentified TSE in USA cattle. all this has been proven, but the TSE in USA cattle has been totally ignored for decades. i will document this data below in my references.

5. UNTIL we ban all ruminant by-products from being fed back to ALL ruminants, until we rapid TSE test (not only deer/elk) but cattle in sufficient numbers to find (1 million rapid TSE test in USA cattle annually for 5 years), any partial measures such as the ones proposed while ignoring sub-clinical TSEs and not rapid TSE testing cattle, not closing down feed mills that continue to violate the FDA's BSE feed regulation (21 CFR 589.2000) and not making freely available those violations, will only continue to spread these TSE mad cow agents in the USA. I am curious what we will call a phenotype in a species that is mixed with who knows how many strains of scrapie, who knows what strain or how many strains of TSE in USA cattle, and the CWD in deer and elk (no telling how many strains there), but all of this has been rendered for animal feeds in the USA for decades. it will get interesting once someone starts looking in all species, including humans here in the USA, but this has yet to happen...

6. IT is paramount that CJD be made reportable in every state (especially ''sporadic'' cjd), and that a CJD Questionnaire must be issued to every family of a victim of TSE. only checking death certificates will not be sufficient. this has been proven as well (see below HISTORY OF CJD -- CJD QUESTIONNAIRE)

7. WE must learn from our past mistakes, not continue to make the same mistakes...

Mule deer fawns (Odocoileus hemionus) were inoculated orally with a brain homogenate prepared from mule deer with naturally occurring chronic wasting disease (CWD), a prion-induced transmissible spongiform encephalopathy. Fawns were necropsied and examined for PrP res, the abnormal prion protein isoform, at 10, 42, 53, 77, 78 and 80 days post-inoculation (p.i.) using an immunohistochemistry assay modified to enhance sensitivity. PrPres was detected in alimentary-tract-associated lymphoid tissues (one or more of the following: retropharyngeal lymph node, tonsil, Peyer's patch and ileocaecal lymph node) as early as 42 days p.i. and in all fawns examined thereafter (53 to 80 days p.i.). No PrPres staining was detected in lymphoid tissue of three control fawns receiving a control brain inoculum, nor was PrPres detectable in neural tissue of any fawn. PrPres-specific staining was markedly enhanced by sequential tissue treatment with formic acid, proteinase K and hydrated autoclaving prior to immunohistochemical staining with monoclonal antibody F89/160.1.5. These results indicate that CWD PrP res can be detected in lymphoid tissues draining the alimentary tract within a few weeks after oral exposure to infectious prions and may reflect the initial pathway of CWD infection in deer. The rapid infection of deer fawns following exposure by the most plausible natural route is consistent with the efficient horizontal transmission of CWD in nature and enables accelerated studies of transmission and pathogenesis in the native species.

snip...

These results indicate that mule deer fawns develop detectable PrP res after oral exposure to an inoculum containing CWD prions. In the earliest post-exposure period, CWD PrPres was traced to the lymphoid tissues draining the oral and intestinal mucosa (i.e. the retropharyngeal lymph nodes, tonsil, ileal Peyer's patches and ileocaecal lymph nodes), which probably received the highest initial exposure to the inoculum. Hadlow et al. (1982) demonstrated scrapie agent in the tonsil, retropharyngeal and mesenteric lymph nodes, ileum and spleen in a 10-month-old naturally infected lamb by mouse bioassay. Eight of nine sheep had infectivity in the retropharyngeal lymph node. He concluded that the tissue distribution suggested primary infection via the gastrointestinal tract. The tissue distribution of PrPres in the early stages of infection in the fawns is strikingly similar to that seen in naturally infected sheep with scrapie. These findings support oral exposure as a natural route of CWD infection in deer and support oral inoculation as a reasonable exposure route for experimental studies of CWD.

Article

Experimental oral transmission of chronic wasting disease to red deer (Cervus elaphus elaphus): Early detection and late stage distribution of protease-resistant prion protein

Aru Balachandran, Noel P. Harrington, James Algire, Andrei Soutyrine, Terry R. Spraker, Martin Jeffrey, Lorenzo González, Katherine I. O’Rourke

Abstract — Chronic wasting disease (CWD), an important emerging prion disease of cervids, is readily transmitted by intracerebral or oral inoculation from deer-to-deer and elk-to-elk, suggesting the latter is a natural route of exposure. Studies of host range susceptibility to oral infection, particularly of those species found in habitats where CWD currently exists are imperative. This report describes the experimental transmission of CWD to red deer following oral inoculation with infectious CWD material of elk origin. At 18 to 20 months post-inoculation, mild to moderate neurological signs and weight loss were observed and animals were euthanized and tested using 3 conventional immunological assays. The data indicate that red deer are susceptible to oral challenge and that tissues currently used for CWD diagnosis show strong abnormal prion (PrPCWD) accumulation. Widespread peripheral PrPCWD deposition involves lymphoreticular tissues, endocrine tissues, and cardiac muscle and suggests a potential source of prion infectivity, a means of horizontal transmission and carrier state.

SNIP...

There is a strong correlation between the presence of PrPTSE and infectivity in prion diseases. Although the epidemiologic evidence strongly suggests that CWD is not transmissible to humans, this study and others suggest caution in this regard. The finding of PrPCWD in various organs, albeit in clinical CWD, suggests that humans who consume or handle meat from CWD-infected red deer may be at risk of exposure to CWD prions. This study found that red deer tissues other than nervous and lymphoid tissue can support CWD prion replication and accumulation. As a result, the consumption or handling of meat from CWD-infected red deer will put humans at risk of exposure to CWD prions. In spite of a well-documented species barrier, a cautious approach would involve preventing such tissues from entering the animal and human food chains. Future studies will require sensitive and quantitative techniques such as bioassays in transgenic mice that assess tissue infectivity and quantitative immunoassays adapted to PrPCWD detection in peripheral tissues.

SNIP...

The exact mode of transmission of CWD in nature remains unclear but is believed to involve direct animal-to-animal contact or environmental contamination. As TSE agents are extremely resistant in the environment (39), oral exposure is the most plausible pathway by which the CWD prion may be introduced to deer in nature and represents a significant obstacle to eradication of CWD from either farmed or free-ranging cervid populations. The distribution of PrPCWD in gut-associated lymphoid tissues, salivary glands, and nasal mucosa in the red deer of this study suggests potential routes of PrPCWD shedding into the environment via fluids such as saliva or feces. However, this study did not identify the point at which an animal may become infectious during the course of infection. An improved understanding of the mechanisms of shedding and transmission will be important in the future management of CWD. SNIP... In summary, this study demonstrates the potential for oral transmission of CWD to red deer and describes the pattern of PrPCWD accumulation for this species. The current surveillance testing regime for cervids would be expected to identify CWD-infected red deer should it occur in North America. These results confirm the usefulness of rapid tests such as ELISA but with generally slightly lower sensitivity when compared with IHC when testing tissues with patchy or sporadic PrPCWD deposition. The finding of PrPCWD in several extraneural tissues including cardiac muscle and the endocrine system suggests that further investigation and monitoring of the potential transmissibility to other species including humans is warranted.

ADAPTATION OF CHRONIC WASTING DISEASE (CWD) INTO HAMSTERS, EVIDENCE OF A WISCONSIN STRAIN OF CWD

Chad Johnson1, Judd Aiken2,3,4 and Debbie McKenzie4,5 1 Department of Comparative Biosciences, University of Wisconsin, Madison WI, USA 53706 2 Department of Agriculture, Food and Nutritional Sciences, 3 Alberta Veterinary Research Institute, 4.Center for Prions and Protein Folding Diseases, 5 Department of Biological Sciences, University of Alberta, Edmonton AB, Canada T6G 2P5 The identification and characterization of prion strains is increasingly important for the diagnosis and biological definition of these infectious pathogens. Although well-established in scrapie and, more recently, in BSE, comparatively little is known about the possibility of prion strains in chronic wasting disease (CWD), a disease affecting free ranging and captive cervids, primarily in North America. We have identified prion protein variants in the white-tailed deer population and demonstrated that Prnp genotype affects the susceptibility/disease progression of white-tailed deer to CWD agent. The existence of cervid prion protein variants raises the likelihood of distinct CWD strains. Small rodent models are a useful means of identifying prion strains. We intracerebrally inoculated hamsters with brain homogenates and phosphotungstate concentrated preparations from CWD positive hunter-harvested (Wisconsin CWD endemic area) and experimentally infected deer of known Prnp genotypes. These transmission studies resulted in clinical presentation in primary passage of concentrated CWD prions. Subclinical infection was established with the other primary passages based on the detection of PrPCWD in the brains of hamsters and the successful disease transmission upon second passage. Second and third passage data, when compared to transmission studies using different CWD inocula (Raymond et al., 2007) indicate that the CWD agent present in the Wisconsin white-tailed deer population is different than the strain(s) present in elk, mule-deer and white-tailed deer from the western United States endemic region

Risk of oral infection with bovine spongiform encephalopathy agent in primates

Corinne Ida Lasmézas, Emmanuel Comoy, Stephen Hawkins, Christian Herzog, Franck Mouthon, Timm Konold, Frédéric Auvré, Evelyne Correia, Nathalie Lescoutra-Etchegaray, Nicole Salès, Gerald Wells, Paul Brown, Jean-Philippe Deslys Summary The uncertain extent of human exposure to bovine spongiform encephalopathy (BSE)--which can lead to variant Creutzfeldt-Jakob disease (vCJD)--is compounded by incomplete knowledge about the efficiency of oral infection and the magnitude of any bovine-to-human biological barrier to transmission. We therefore investigated oral transmission of BSE to non-human primates. We gave two macaques a 5 g oral dose of brain homogenate from a BSE-infected cow. One macaque developed vCJD-like neurological disease 60 months after exposure, whereas the other remained free of disease at 76 months. On the basis of these findings and data from other studies, we made a preliminary estimate of the food exposure risk for man, which provides additional assurance that existing public health measures can prevent transmission of BSE to man.

SNIP...


Long-term effects of CWD on cervid populations and ecosystems remain unclear as the disease continues to spread and prevalence increases. In captive herds, CWD might persist at high levels and lead to complete herd destruction in the absence of human culling. Epidemiologic modeling suggests the disease could have severe effects on free-ranging deer populations, depending on hunting policies and environmental persistence (8,9). CWD has been associated with large decreases in free-ranging mule deer populations in an area of high CWD prevalence (Boulder, Colorado, USA) (5).

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.




Despite the five year premise plan and site decontamination, The WI DNR has concerns over the bioavailability of infectious prions at this site to wild white-tail deer should these fences be removed. Current research indicates that prions can persist in soil for a minimum of 3 years.


However, Georgsson et al. (2006) concluded that prions that produced scrapie disease in sheep remained bioavailable and infectious for at least 16 years in natural Icelandic environments, most likely in contaminated soil.


Additionally, the authors reported that from 1978-2004, scrapie recurred on 33 sheep farms, of which 9 recurrences occurred 14-21 years after initial culling and subsequent restocking efforts; these findings further emphasize the effect of environmental contamination on sustaining TSE infectivity and that long-term persistence of prions in soils may be substantially greater than previously thought. < < <

Swine Are Susceptible to Chronic Wasting Disease by Intracerebral Inoculation


http://chronic-wasting-disease.blogspot.com/2011/07/swine-are-susceptible-to-chronic.html






Oral.29: Susceptibility of Domestic Cats to CWD Infection

Amy Nalls, Nicholas J. Haley, Jeanette Hayes-Klug, Kelly Anderson, Davis M. Seelig, Dan S. Bucy, Susan L. Kraft, Edward A. Hoover and Candace K. Mathiason† Colorado State University; Fort Collins, CO USA†Presenting author; Email: ckm@lamar.colostate.edu

Domestic and non-domestic cats have been shown to be susceptible to one prion disease, feline spongiform encephalopathy (FSE), thought to be transmitted through consumption of bovine spongiform encephalopathy (BSE) contaminated meat. Because domestic and free ranging felids scavenge cervid carcasses, including those in CWD affected areas, we evaluated the susceptibility of domestic cats to CWD infection experimentally. Groups of n = 5 cats each were inoculated either intracerebrally (IC) or orally (PO) with CWD deer brain homogenate. Between 40–43 months following IC inoculation, two cats developed mild but progressive symptoms including weight loss, anorexia, polydipsia, patterned motor behaviors and ataxia—ultimately mandating euthanasia. Magnetic resonance imaging (MRI) on the brain of one of these animals (vs. two age-matched controls) performed just before euthanasia revealed increased ventricular system volume, more prominent sulci, and T2 hyperintensity deep in the white matter of the frontal hemisphere and in cortical grey distributed through the brain, likely representing inflammation or gliosis. PrPRES and widely distributed peri-neuronal vacuoles were demonstrated in the brains of both animals by immunodetection assays. No clinical signs of TSE have been detected in the remaining primary passage cats after 80 months pi. Feline-adapted CWD was sub-passaged into groups (n=4 or 5) of cats by IC, PO, and IP/SQ routes. Currently, at 22 months pi, all five IC inoculated cats are demonstrating abnormal behavior including increasing aggressiveness, pacing, and hyper responsiveness. Two of these cats have developed rear limb ataxia. Although the limited data from this ongoing study must be considered preliminary, they raise the potential for cervid-to-feline transmission in nature.

Soil-mediated prion transmission: Is local soil-type a key determinant of prion disease incidence?

Department of Civil Engineering, University of Nebraska-Lincoln, Peter Kiewit Institute, Omaha, NE 68182, USA.

Abstract

Prion diseases, including chronic wasting disease (CWD) and scrapie, can be transmitted via indirect environmental routes. Animals habitually ingest soil, and results from laboratory experiments demonstrate prions can bind to a wide range of soils and soil minerals, retain the ability to replicate, and remain infectious, indicating soil could serve as a reservoir for natural prion transmission and a potential prion exposure route for humans. Preliminary epidemiological modeling suggests soil texture may influence the incidence of prion disease. These results are supported by experimental work demonstrating variance in prion interactions with soil, including variance in prion soil adsorption and soil-bound prion replication with respect to soil type. Thus, local soil type may be a key determinant of prion incidence. Further experimental and epidemiological work is required to fully elucidate the dynamics of soil-mediated prion transmission, an effort that should lead to effective disease management and mitigation strategies.

Survival and Limited Spread of TSE Infectivity after Burial


Karen Fernie, Allister Smith and Robert A. Somerville The Roslin Institute and R(D)SVS; University of Edinburgh; Roslin, Scotland UK

Scrapie and chronic wasting disease probably spread via environmental routes, and there are also concerns about BSE infection remaining in the environment after carcass burial or waste 3disposal. In two demonstration experiments we are determining survival and migration of TSE infectivity when buried for up to five years, as an uncontained point source or within bovine heads. Firstly boluses of TSE infected mouse brain were buried in lysimeters containing either sandy or clay soil. Migration from the boluses is being assessed from soil cores taken over time. With the exception of a very small amount of infectivity found 25 cm from the bolus in sandy soil after 12 months, no other infectivity has been detected up to three years. Secondly, ten bovine heads were spiked with TSE infected mouse brain and buried in the two soil types. Pairs of heads have been exhumed annually and assessed for infectivity within and around them. After one year and after two years, infectivity was detected in most intracranial samples and in some of the soil samples taken from immediately surrounding the heads. The infectivity assays for the samples in and around the heads exhumed at years three and four are underway. These data show that TSE infectivity can survive burial for long periods but migrates slowly. Risk assessments should take into account the likely long survival rate when infected material has been buried. The authors gratefully acknowledge funding from DEFRA.

Degradation of Pathogenic Prion Protein and Prion Infectivity by Lichens

Christopher J. Johnson,1 James P. Bennett,1 Steven M. Biro,1,2 Cynthia M. Rodriguez,1,2 Richard A. Bessen3 and Tonie E. Rocke1 1USGS National Wildlife Health Center; 2Department of Bacteriology; University of Wisconsin, Madison; 3Department of Veterinary Molecular Biology; Montana State University; Bozeman, MT USA

Key words: prion, lichen, bioassay, protease, degradation

Few biological systems have been identified that degrade the transmissible spongiform encephalopathy (TSE)-associated form of the prion protein (PrPTSE) and TSE infectivity. Stability of the TSE agent allows scrapie and chronic wasting disease agents to persist in the environment and cause disease for years. Naturally-occurring or engineered processes that reduce infectivity in the environment could aid in limiting environmental TSE transmission. We have previously identified that species of at least three lichens, unusual, symbiotic organisms formed from a fungus and photosynthetic partner, contain a serine protease capable of degrading PrPTSE under gentle conditions. We tested the hypothesis that lichen extracts from these three species reduce TSE infectivity by treating infected brain homogenate with extracts and examining infectivity in mice. We found lichen extracts diminished TSE infectious titer by factors of 100 to 1,000 and that reductions in infectivity were not well-correlated with the extent of PrPTSE degradation observed by immunoblotting. For example, treatment of brain homogenate with Cladonia rangiferina extract caused <100-fold reduction in PrP immunoreactivity but ~1,000-fold decrease in infectivity, suggesting that some PrPTSE remaining after extract treatment was rendered uninfectious or that the lichen protease favors more infectious forms of PrPTSE. Our data also indicate that lichen species closely related to those with prion-degrading protease activity do not necessarily degrade PrPTSE. Characterization of the lichen species-specificity of PrPTSE degradation within the genera Cladonia and Usnea and comparison with known lichen phylogeny has yielded clusters of species on which to focus searches for anti-prion agents.

PPo8-14: Enzymatic Digestion of Chronic Wasting Disease Prions Bound to Soil

Samuel E. Saunders,1 Jason C. Bartz,2 Kurt C. Vercauteren3 and Shannon L. Bartelt-Hunt1 1Department of Civil Engineering; University of Nebraska-Lincoln; Peter Kiewit Institute; Omaha, Nebraska USA; 2Department of Medical Microbiology and Immunology; Creighton University; Omaha, Nebraska USA; 3USDA; Animal and Plant Health Inspection Service; Wildlife Services; National Wildlife Research Center; Fort Collins, CO USA

Chronic wasting disease (CWD) and sheep scrapie can be transmitted via indirect environmental routes, and it is known that soil can serve as a reservoir of prion infectivity. Given the strong interaction between the prion protein (PrP) and soil, we hypothesized that binding to soil enhances prion resistance to enzymatic digestion, thereby facilitating prion longevity in the environment and providing protection from host degradation. We characterized the performance of a commercially available subtilisin enzyme, the Prionzyme, to degrade soil-bound and unbound CWD and HY TME PrP as a function of pH, temperature, and treatment time. The subtilisin enzyme effectively degraded PrP adsorbed to a wide range of soils and soil minerals below the limits of detection. Signal loss occurred rapidly at high pH (12.5) and within 7 d under conditions representative of the natural environment (pH 7.4, 22°C). Serial PMCA of treated soil samples suggests a greater than 6-log decrease in infectious titer compared with controls. We observed no apparent difference in enzyme effectiveness between bound and unbound CWD PrP. Our results show that although adsorbed prions do retain relative resistance to enzymatic digestion compared with other brain homogenate proteins, they can be effectively degraded when bound to soil. Our results also suggest a topical application of a subtilisin enzyme solution may be an effective decontamination method to limit disease transmission via environmental ‘hot spots’ of prion infectivity.

Detection of PrPCWD in Rocky Mountain Elk Feces Using Protein Misfolding Cyclic Amplification

Bruce E Pulford,1 Terry Spraker,1 Jenny Powers,2 Margaret Wild2 and Mark D. Zabel1 1Department of Microbiology; Immunology and Pathology; College of Veterinary Medicine and Biomedical Sciences; Colorado State University; 2Biological Resource Management Division; United States National Park Service; CO, USA

Key words: CWD, feces, PMCA, elk

Chronic wasting disease (CWD) is a transmissible spongiform encephalopathy affecting cervids, including mule and white-tailed deer (Odocoileus hemionus and virginianus), elk (Cervus elaphus nelsoni) and moose (Alces alces shirasi). The method of CWD transmission between hosts is unclear, though there is evidence that feces excreted by infected animals may play a role. Recently, CWD prions was detected in feces using bioassays in cervidized mice, which took many months to produce results. In this study, we use a more rapid procedure, protein misfolding cyclic amplification (PMCA), to test elk feces for the presence of PK-resistant cervid PrP (PrPCWD). Feces were collected from symptomatic and asymptomatic elk in several northern Colorado locations, homogenized, mixed with normal brain homogenate from Tg5037 mice (expressing cervid PrP) and subjected to up to 9 rounds of PMCA (1 round = 40 secs sonication/30 mins at 70% maximum power, 24 hours). Western blots were used to detect PrPCWD using BAR-224 anti-PrP antibody. Rectal and CNS tissue from the elk were IHC-labeled and examined for the presence of PrPCWD. Fecal samples from symptomatic and asymptomatic elk that tested positive by IHC showed characteristic PrPCWD bands on western blots following PMCA. In addition, PMCA detected PrPCWD in 25% of fecal samples from IHC-negative animals. These data suggest that PMCA may (1) prove useful as a non-invasive method to supplement or even replace IHC testing of cervids for CWD, and (2) identify additional asymptomatic carriers of CWD, the prevalence of which may be underestimated using IHC.

Detection of CWD Prions in Salivary and Urinary Tissues of Deer: Potential Mechanisms of Pathogenesis and Prion Shedding

Nicholas J. Haley,1 Candace K. Mathiason,1 Glenn C. Telling2 and Edward A. Hoover1 1Department of Microbiology, Immunology and Pathology; College of Veterinary Medicine and Biomedical Sciences; Colorado State University; Fort Collins, Colorado USA; 2Department of Molecular Biology and Genetics; University of Kentucky; Lexington, Kentucky USA

Key words: chronic wasting disease, transmission, PMCA, pathogenesis, excretion, urine, saliva, salivary gland, urinary bladder, kidney, blood

Saliva and urine are thought to play an important role in the transmission and pathogenesis of chronic wasting disease (CWD) in captive and free-ranging cervids. We have previously identified PrPCWD in a variety of excreta using serial PMCA (sPMCA) and bioassay; however the source of infectious prions in urine and saliva has yet to be identified. In the present study, we applied sPMCA to tissues associated with saliva and urine production and excretion in an effort to seek proximal sources of prion shedding. Oropharyngeal and urogenital tissues, along with blood and obex from CWD-exposed cervids (comprising over 300 individual samples) were analyzed blindly in duplicate and scored based on apparent CWD burden. PrPCWD was detected by three rounds of sPMCA in tissues associated with saliva and urine production and excretion, notably salivary gland and urinary bladder; whereas blood samples from the same animals and concurrent negative controls (n = 116 of 117) remained negative. Route of inoculation and CNS burden appeared to play an important role in terminal prion distribution, in that IV-inoculated animals and those with increasing CNS levels of PrPCWD had higher and more widely distributed accumulation in excretory tissues. PMCA identification of PrPCWD in oropharyngeal and urogenital tissues—in the absence of detection by conventional methods—may indicate the presence of protease- sensitive infectious prions in excretory tissues not revealed by assays employing PK digestion or other means to remove PrPC reactivity. Thus, evaluation of peripheral tissues via sPMCA may allow additional insights into prion transmission, trafficking and pathogenesis.

Identification of Renal Origin for CWD Urinary Prion Excretion in Deer

Davis M. Seelig,1 Nicholas J. Haley,1 Jan P. Langeveld and Edward A. Hoover1 1Colorado State University; Department of Microbiology, Immunology and Pathology; Fort Collins, CO USA; 2Central Institute for Animal Disease Control (CIDC-Lelystad); Lelystad, The Netherlands

Chronic wasting disease (CWD) is an efficiently transmitted prion disease of cervids. Although bioassays have confirmed the presence of infectious prions in urine and other body fluids of infected deer, origin and mechanisms of prion transfer to and shedding in excreta remains unknown. To address these questions, we have developed enhanced immunohistochemistry (IHC) methods employing tyramide signal amplification (TSA) on formalin-fixed, paraffin-embedded (FFPE) tissues of n = 20 CWD-infected white-tailed deer. Using these methods we have demonstrated PrPCWD present granular to clumped aggregates both within the cytoplasm of renal tubule cells and in the interstitium. Cytoplasmic PrPCWD aggregates were detected most commonly in proximal convoluted tubule epithelial cells. PrPCWD was not identified in the lower urinary tract (ureters or bladder) of any CWD-infected animal. In summary, we present evidence for PrPCWD accumulation within the renal tubule cells, which may identify a proximate tissue source and explain the manner by which infectious prions are excreted in the urine of infected deer, thereby leading to the high degree of direct and indirect horizontal transmission of chronic wasting disease.

Elk from Olmsted County herd depopulated to control CWD Three additional elk from the 558-head herd tested positive

News Release For Immediate Release: Friday October 30, 2009 Contact: Malissa Fritz, BAH Communications Director

Elk from Olmsted County herd depopulated to control CWD ST. PAUL, MINN. – The Minnesota Board of Animal Health announced today that the farmed elk herd in Olmsted County has been depopulated and tested for Chronic Wasting Disease (CWD).

In January, 2009, a female elk from the herd tested positive for CWD. The remaining elk in the herd were removed to minimize the risk of CWD spreading to other farmed deer and elk or to wild white-tailed deer in the area. Marksmen from Wildlife Services, a division of the United States Department of Agriculture (USDA), euthanized the animals in September.

USDA, Veterinary Services and Board personnel collected samples from each elk. Those samples were submitted to the U.S. Department of Agriculture’s National Veterinary Services Laboratory (NVSL) in Ames, Iowa for testing. Three additional elk from the 558-head herd tested positive for CWD, one male and two females.

In 2003, Minnesota implemented mandatory registration and CWD surveillance programs for farmed cervidae herds (members of the deer and elk family). When farmed cervidae over 16 months of age die or are slaughtered, herd owners must submit brain samples for CWD testing.

CWD is a fatal brain and nervous system disease found in cervidae in certain parts of North America. The disease is caused by an abnormally shaped protein called a prion, which can damage brain and nerve tissue. Infected animals show progressive loss of body weight with accompanying behavioral changes. In later stages of the disease, infected animals become emaciated (thus “wasting” disease). Other signs include staggering, consuming large amounts of water, excessive urination and drooling.

According to state health officials and the Centers for Disease Control and Prevention, there is no evidence that CWD can be transmitted to humans.

Chronic wasting disease in 3 elk among 560 shot near Rochester Fears that disease could spread to wild deer prompted slaughter.

By MATT McKINNEY, Star Tribune

Last update: October 30, 2009 - 11:17 PM

Sharpshooters killed a farm herd of some 560 elk near Rochester this month, and tests of the animals found three infected with chronic wasting disease, state officials said Friday. The slaughter was ordered after one of the animals tested positive for the disease in January.

The animals lived on the 1,300-acre Elk Farm LLC near Pine Island, the largest elk farm in the state. The farm, bought by Tower Investments of Woodland, Calif., in 2006, is part of a 2,300-acre tract set to become a bioscience research and manufacturing center called Elk Run, with offices, shops, homes and 15 to 25 companies.

The carcasses were sent to a landfill, except for the three that tested positive, which were destroyed at a special facility at the University of Minnesota. The U.S. Department of Agriculture (USDA) paid Tower Investments a fair market value for the elk, said Paul Anderson, assistant director of the Minnesota Board of Animal Health.

The USDA sharpshooters began shooting the animals last month. Tests were conducted at a USDA lab in Ames, Iowa.

Chronic wasting disease kills elk and deer after infecting their brains and nervous system. The animals spread it through nose-to-nose contact. It does not spread to people. It was first detected in farmed elk in 2002, prompting fears that it could spread to the state's population of some 1 million wild deer.

Seven Deer Test Positive for Chronic Wasting Disease During 2009 Spring Collections in Hampshire County, West Virginia


Test results have detected the Chronic Wasting Disease (CWD) agent in a total of seven white-tailed deer sampled during the 2009 spring collections in Hampshire County, according to the West Virginia Division of Natural Resources (DNR).

These most recent deer testing positive for CWD were collected by Wildlife Resources Section personnel working in cooperation with local landowners, and they were all located within the Hampshire County CWD Containment Area (i.e., that portion of Hampshire County located North of U.S. Route 50). The CWD agent previously has been detected outside the containment area in the adjacent portion of Hampshire County, and the area of known infected deer does continue to slowly expand.

These collections have been designed to investigate and determine the prevalence and distribution of the disease in Hampshire County. In addition, wildlife biologists are carefully monitoring changes in the structure of the deer herd within the CWD containment area.

The first case of CWD in West Virginia was confirmed on September 2, 2005. Since then, DNR has been fully engaged in activities guided by its CWD Incident Response Plan, which is designed to accomplish the following objectives.

Determine the distribution and prevalence of CWD through enhanced surveillance efforts. Communicate and coordinate with the public and other appropriate agencies on issues relating to CWD and the steps being taken to respond to this disease. Initiate appropriate management actions necessary to control the spread of this disease and prevent further introduction of the disease. To date, CWD surveillance efforts conducted by the DNR have resulted in a total of 45 deer being confirmed positive for CWD in Hampshire County. Ongoing and extensive surveillance efforts being conducted by Wildlife Resources Section personnel throughout West Virginia have not detected CWD outside of Hampshire County.

CWD is a neurological disease found in deer and elk, and it belongs to a family of diseases known as transmissible spongiform encephalopathies. The disease is thought to be caused by abnormal, proteinaceous particles called prions that slowly attack the brain of infected deer and elk, causing the animals to progressively become emaciated, display abnormal behavior and invariably results in the death of the infected animal. There is no known treatment for CWD, and it is fatal for the infected deer or elk. It is important to note that currently there is no evidence to suggest CWD poses a risk for humans or domestic animals.

“Landowner and hunter cooperation throughout this entire CWD surveillance effort in Hampshire County continues to be excellent,” noted DNR Director Frank Jezioro. “As we strive to meet this wildlife disease challenge and implement appropriate management strategies, the support and involvement of landowners and hunters remains essential. DNR is committed to keeping the public informed and involved in these wildlife disease management actions.

“Our well trained and professional wildlife biologists, wildlife managers and conservation officers are working diligently to effectively address this wildlife disease threat, and we are collaborating with nationally recognized wildlife disease experts at the Southeastern Cooperative Wildlife Disease Study in Athens, Georgia,” said Jezioro.

Mark Marraccini, a spokesman for the Kentucky Department of Fish and Wildlife, said a new law that takes effect this summer also bans the importation of cervid animals into the state, but allows certain exemptions.

For example, the law will allow the animals to be imported if they are from a herd that has been disease-free for five years and is from a disease-free state, Marraccini said.

MY COMMENTS AND FACTS AS FOLLOWS ;

One elk was euthanized 63 months post-inoculation without exhibiting clinical signs, but had PrP**d accumulation in CNS and peripheral lymphoid tissues.

CWD, GAME FARMS, BAITING, AND POLITICS

CWD Infection Studies in Two Species of Non-Human Primates

Bruce Chesebro Laboratory of Persistent Virus Diseases, Rocky Mountain Laboratories, Hamilton, Montana USA 59840.

CWD is a TSE/prion disease present in wild and domestic cervid populations of North America. CWD from cervids might possibly spread to humans who hunt and eat these species and to domestic animals such as cattle, sheep or horses sharing the same habitat. Therefore, it is important to understand the potential for spread of CWD to other species. Laboratory experiments have shown that CWD does not cause disease in transgenic mice expressing human PrP, suggesting that humans and other primates might be resistant to this infection. However, earlier data from the laboratory of Richard Marsh found that squirrel monkeys could be infected by intracerebral CWD inoculation. We recently followed up this work extending it to studies of two primate species, squirrel monkeys and Cynomolgus macaques. We also compared intracerebral and oral routes of infection. To search for possible CWD variant strains we analyzed 8 different CWD pools obtained from wild or domestic elk, mule deer and white-tailed deer. The results of these experiments will be presented.

This article has been cited by other articles in PMC. Top AbstractChronic wasting disease (CWD) is an emerging prion disease of deer and elk. The risk of CWD transmission to humans following exposure to CWD-infected tissues is unknown. To assess the susceptibility of nonhuman primates to CWD, two squirrel monkeys were inoculated with brain tissue from a CWD-infected mule deer. The CWD-inoculated squirrel monkeys developed a progressive neurodegenerative disease and were euthanized at 31 and 34 months postinfection. Brain tissue from the CWD-infected squirrel monkeys contained the abnormal isoform of the prion protein, PrP-res, and displayed spongiform degeneration. This is the first reported transmission of CWD to primates.

THE ENVIRONMENT AS A RESERVOIR OF PRION INFECTIVITY

An environmental reservoir of prion infectivity has long been known to be a source of infection of sheep scrapie and likely plays an even more important role in the transmission of chronic wasting disease (CWD) in elk, deer and moose. Prion infectivity is extremely resistant to degradation, resulting in an environmental persistence of infectious agent. CWD is a contagious disease of free-ranging cervids. Infected deer and elk release infectious agent into the environment from body fluids and from diseased animal carcasses. The rapid expansion of CWD in North America represents a significant and continued environmental risk not only to cervids but to other species as well. Our work has demonstrated that prion protein, including PrPCWD, binds avidly to soil and soil components. Significantly, prion/soil binding enhances disease transmission suggesting that the soils, once contaminated with infectious prions, plays a critical role in maintaining and perpetuating prion infections.

ADAPTATION OF CHRONIC WASTING DISEASE (CWD) INTO HAMSTERS, EVIDENCE OF A WISCONSIN STRAIN OF CWD

Chad Johnson1, Judd Aiken2,3,4 and Debbie McKenzie4,5 1 Department of Comparative Biosciences, University of Wisconsin, Madison WI, USA 53706 2 Department of Agriculture, Food and Nutritional Sciences, 3 Alberta Veterinary Research Institute, 4.Center for Prions and Protein Folding Diseases, 5 Department of Biological Sciences, University of Alberta, Edmonton AB, Canada T6G 2P5 The identification and characterization of prion strains is increasingly important for the diagnosis and biological definition of these infectious pathogens. Although well-established in scrapie and, more recently, in BSE, comparatively little is known about the possibility of prion strains in chronic wasting disease (CWD), a disease affecting free ranging and captive cervids, primarily in North America. We have identified prion protein variants in the white-tailed deer population and demonstrated that Prnp genotype affects the susceptibility/disease progression of white-tailed deer to CWD agent. The existence of cervid prion protein variants raises the likelihood of distinct CWD strains. Small rodent models are a useful means of identifying prion strains. We intracerebrally inoculated hamsters with brain homogenates and phosphotungstate concentrated preparations from CWD positive hunter-harvested (Wisconsin CWD endemic area) and experimentally infected deer of known Prnp genotypes. These transmission studies resulted in clinical presentation in primary passage of concentrated CWD prions. Subclinical infection was established with the other primary passages based on the detection of PrPCWD in the brains of hamsters and the successful disease transmission upon second passage. Second and third passage data, when compared to transmission studies using different CWD inocula (Raymond et al., 2007) indicate that the CWD agent present in the Wisconsin white-tailed deer population is different than the strain(s) present in elk, mule-deer and white-tailed deer from the western United States endemic region.

Cross-sequence transmission of sporadic Creutzfeldt-Jakob disease creates a new prion strain

Date: August 25, 2007 at 12:42 pm PST

our results raise the possibility that CJD cases classified as VV1 may include cases caused by iatrogenic transmission of sCJD-MM1 prions or food-borne infection by type 1 prions from animals, e.g., chronic wasting disease prions in cervid. In fact, two CJD-VV1 patients who hunted deer or consumed venison have been reported (40, 41). The results of the present study emphasize the need for traceback studies and careful re-examination of the biochemical properties of sCJD-VV1 prions.

Clearly, it is premature to draw firm conclusions about CWD passing naturally into humans, cattle and sheep, but the present results suggest that CWD transmissions to humans would be as limited by PrP incompatibility as transmissions of BSE or sheep scrapie to humans. Although there is no evidence that sheep scrapie has affected humans, it is likely that BSE has caused variant CJD in 74 people (definite and probable variant CJD cases to date according to the UK CJD Surveillance Unit). Given the presumably large number of people exposed to BSE infectivity, the susceptibility of humans may still be very low compared with cattle, which would be consistent with the relatively inefficient conversion of human PrP-sen by PrPBSE. Nonetheless, since humans have apparently been infected by BSE, it would seem prudent to take reasonable measures to limit exposure of humans (as well as sheep and cattle) to CWD infectivity as has been recommended for other animal TSEs.

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.
