North Carolina Captive cervid licenses and permits Senate Bill 744
Singeltary Submission
Greetings North Carolina Wildlife Officials, and Hunters et al,
I kindly wish to submit the latest science on the Chronic Wasting Disease
CWD Transmissible Spongiform Encephalopathy TSE Prion disease.
I have followed the science and peer review studies on these TSE prion
disease daily since the death of my mother to the Heidenhain Variant of
Creutzfeldt Jakob Disease hvCJD ‘confirmed’ December 14, 1997.
I have learned that when officials are making decisions on cervids and
other animals, when it comes to the TSE prion disease, it seems that all the
latest science is NOT available to the general public, and officials seem just
ignore it, to make sound decisions. like the latest risk factors for the
environment, risk factors to other species, risk factors to humans, the latest
science, not science that is 30 years old.
I kindly wish to pass this science on the CWD TSE prion disease to you to
use as you wish. ...Good Luck!
North Carolina Captive cervid licenses and permits Senate Bill 744
Singeltary Submission
Proposal Number / Title
Captive cervid licenses and permits
Justification Senate Bill 744 ratified in the 2014 session of the General
Assembly contains six sections that direct the Commission to change how captive
cervids are managed. Section 14.26(c) reads as follows “Nothing in this section
is intended to limit the issuance by the Commission of new captivity licenses or
permits for cervid facilities containing only cervids originating within the
State from facilities with an existing captivity license or permit that have
achieved certified status.” In order to respond in a timely manner to the
intention of the General Assembly identified in this section, the Commission is
initiating temporary rule-making.
Description
The proposed changes to 15A NACA 10H .0301 would allow the Commission to
issue new captivity licenses and permits for the purpose of holding cervids in
captivity and allow certified herd owners to sell or transfer cervids to any
licensed facility. Also, mandatory testing for CWD will be raised from all
cervids that die at age 6 months or older to all cervids that die at age 12
months or older.

*** Wisconsin 16 age limit on testing dead deer Game Farm CWD Testing Protocol Needs To Be Revised
Approximately 4,200 fawns, defined as deer under 1 year of age, were sampled from the eradication zone over the last year. The majority of fawns sampled were between the ages of 5 to 9 months, though some were as young as 1 month.
*** Two of the six fawns with CWD detected were 5 to 6 months old.
All six of the positive fawns were taken from the core area of the CWD eradication zone where the highest numbers of positive deer have been identified.

*** Wisconsin 16 age limit on testing dead deer Game Farm CWD Testing Protocol Needs To Be Revised
*** Conclusion. CWD prions (as inferred by prion seeding activity by RT-QuIC) are shed in urine of infected deer as early as 6 months post inoculation and throughout the subsequent disease course. Further studies are in progress refining the real-time urinary prion assay sensitivity and we are examining more closely the excretion time frame, magnitude, and sample variables in relationship to inoculation route and prionemia in naturally and experimentally CWD-infected cervids.
PRION 2014 CONFERENCE
CHRONIC WASTING DISEASE CWD
A FEW FINDINGS ;
Conclusions. ...To our knowledge, this is the first established
experimental model of CWD in TgSB3985. We found evidence for co-existence or
divergence of two CWD strains adapted to Tga20 mice and their replication in
TgSB3985 mice. Finally, we observed phenotypic differences between
cervid-derived CWD and CWD/Tg20 strains upon propagation in TgSB3985 mice.
Further studies are underway to characterize these strains.
We conclude that TSE infectivity is likely to survive burial for long time
periods with minimal loss of infectivity and limited movement from the original
burial site. However PMCA results have shown that there is the potential for
rainwater to elute TSE related material from soil which could lead to the
contamination of a wider area. These experiments reinforce the importance of
risk assessment when disposing of TSE risk materials.
The results show that even highly diluted PrPSc can bind efficiently to
polypropylene, stainless steel, glass, wood and stone and propagate the
conversion of normal prion protein. For in vivo experiments, hamsters were ic
injected with implants incubated in 1% 263K-infected brain homogenate. Hamsters,
inoculated with 263K-contaminated implants of all groups, developed typical
signs of prion disease, whereas control animals inoculated with non-contaminated
materials did not.
Our data establish that meadow voles are permissive to CWD via peripheral
exposure route, suggesting they could serve as an environmental reservoir for
CWD. Additionally, our data are consistent with the hypothesis that at least two
strains of CWD circulate in naturally-infected cervid populations and provide
evidence that meadow voles are a useful tool for CWD strain typing.
Conclusion. ... CWD prions are shed in saliva and urine of infected deer as
early as 3 months post infection and throughout the subsequent >1.5 year
course of infection. In current work we are examining the relationship of
prionemia to excretion and the impact of excreted prion binding to surfaces and
particulates in the environment.
Conclusion. ... CWD prions (as inferred by prion seeding activity by
RT-QuIC) are shed in urine of infected deer as early as 6 months post
inoculation and throughout the subsequent disease course. Further studies are in
progress refining the real-time urinary prion assay sensitivity and we are
examining more closely the excretion time frame, magnitude, and sample variables
in relationship to inoculation route and prionemia in naturally and
experimentally CWD-infected cervids.
Conclusions. ... Our results suggested that the odds of infection for CWD
is likely controlled by areas that congregate deer thus increasing direct
transmission (deer-to-deer interactions) or indirect transmission
(deer-to-environment) by sharing or depositing infectious prion proteins in
these preferred habitats. Epidemiology of CWD in the eastern U.S. is likely
controlled by separate factors than found in the Midwestern and endemic areas
for CWD and can assist in performing more efficient surveillance efforts for the
region.
Conclusions. ... During the pre-symptomatic stage of CWD infection and
throughout the course of disease deer may be shedding multiple LD50 doses per
day in their saliva. CWD prion shedding through saliva and excreta may account
for the unprecedented spread of this prion disease in nature.

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.

Between 1996 and 2002, chronic wasting disease was diagnosed in 39 herds of
farmed elk in Saskatchewan in a single epidemic. All of these herds were
depopulated as part of the Canadian Food Inspection Agency’s (CFIA) disease
eradication program. Animals, primarily over 12 mo of age, were tested for the
presence CWD prions following euthanasia. Twenty-one of the herds were linked
through movements of live animals with latent CWD from a single infected source
herd in Saskatchewan, 17 through movements of animals from 7 of the secondarily
infected herds.
***The source herd is believed to have become infected via importation of
animals from a game farm in South Dakota where CWD was subsequently diagnosed
(7,4). A wide range in herd prevalence of CWD at the time of herd depopulation
of these herds was observed. Within-herd transmission was observed on some
farms, while the disease remained confined to the introduced animals on other
farms.

Chronic Wasting Disease (CWD) outbreaks and surveillance program in the
Republic of Korea Chronic Wasting Disease (CWD) outbreaks and surveillance
program in the Republic of Korea

Chronic wasting disease (CWD) has been recognized as an important prion
disease in native North America deer and Rocky mountain elks. The disease is a
unique member of the transmissible spongiform encephalopathies (TSEs), which
naturally affects only a few species. CWD had been limited to USA and Canada
until 2000.
On 28 December 2000, information from the Canadian government showed that a
total of 95 elk had been exported from farms with CWD to Korea. These consisted
of 23 elk in 1994 originating from the so-called “source farm” in Canada, and 72
elk in 1997, which had been held in pre export quarantine at the “source
farm”.Based on export information of CWD suspected elk from Canada to Korea, CWD
surveillance program was initiated by the Ministry of Agriculture and Forestry
(MAF) in 2001.
All elks imported in 1997 were traced back, however elks imported in 1994
were impossible to identify. CWD control measures included stamping out of all
animals in the affected farm, and thorough cleaning and disinfection of the
premises. In addition, nationwide clinical surveillance of Korean native
cervids, and improved measures to ensure reporting of CWD suspect cases were
implemented.
Total of 9 elks were found to be affected. CWD was designated as a
notifiable disease under the Act for Prevention of Livestock Epidemics in 2002.
Additional CWD cases - 12 elks and 2 elks - were diagnosed in 2004 and
2005.
Since February of 2005, when slaughtered elks were found to be positive,
all slaughtered cervid for human consumption at abattoirs were designated as
target of the CWD surveillance program. Currently, CWD laboratory testing is
only conducted by National Reference Laboratory on CWD, which is the Foreign
Animal Disease Division (FADD) of National Veterinary Research and Quarantine
Service (NVRQS).
In July 2010, one out of 3 elks from Farm 1 which were slaughtered for the
human consumption was confirmed as positive. Consequently, all cervid – 54 elks,
41 Sika deer and 5 Albino deer – were culled and one elk was found to be
positive. Epidemiological investigations were conducted by Veterinary
Epidemiology Division (VED) of NVRQS in collaboration with provincial veterinary
services.
Epidemiologically related farms were found as 3 farms and all cervid at
these farms were culled and subjected to CWD diagnosis. Three elks and 5
crossbreeds (Red deer and Sika deer) were confirmed as positive at farm 2.
All cervids at Farm 3 and Farm 4 – 15 elks and 47 elks – were culled and
confirmed as negative.
Further epidemiological investigations showed that these CWD outbreaks were
linked to the importation of elks from Canada in 1994 based on circumstantial
evidences.
In December 2010, one elk was confirmed as positive at Farm 5.
Consequently, all cervid – 3 elks, 11 Manchurian Sika deer and 20 Sika deer –
were culled and one Manchurian Sika deer and seven Sika deer were found to be
positive. This is the first report of CWD in these sub-species of deer.
Epidemiological investigations found that the owner of the Farm 2 in CWD
outbreaks in July 2010 had co-owned the Farm 5.
In addition, it was newly revealed that one positive elk was introduced
from Farm 6 of Jinju-si Gyeongsang Namdo. All cervid – 19 elks, 15 crossbreed
(species unknown) and 64 Sika deer – of Farm 6 were culled, but all confirmed as
negative.

Structural effects of PrP polymorphisms on intra- and inter-species prion
transmission
*** Finally, our findings showing that Tg(DeerPrP), but not Tg(ElkPrP) are
sensitive to infection with SSBP/1 belie previously published results showing
that SSBP/1 of the same provenance caused disease in two lines of Tg mice
expressing elk PrP (13). However, our results appear to be consistent with the
reported susceptibilities of elk and deer to sheep prions. In previous studies,
of six elk inoculated with scrapie, three presented with neurological signs and
neuropathology, but only after long and variable times to disease onset ranging
from 25 to 46 months (29). In contrast, our results with SSBP/1 demonstrate
relatively facile transmission of scrapie to deer, with all inoculated animals
developing within 19 to 20 months, which is in accordance with susceptibility of
deer to a US scrapie isolate with a similar time to disease onset (24).
Polymorphisms ovine PrP add a further level of complexity, since they control
the propagation scrapie strains. Occupancy of residue 136 by A or V is of
particular importance. Our previous results indicated that SSBP/1 is comprised
of a dominant strain that is preferentially propagated by sheep PrP encoding V
at 136 (12). In contrast, the scrapie prions used in the deer transmission
studies of Greenlee and colleagues were isolated from a sheep encoding A136,
***raising the possibility that deer may be susceptible to multiple scrapie
strains. ***
Significance
The unpredictable recurrences of prion epidemics, their incurable
lethality, and the capacity of animal prions to infect humans, provide
significant motivation to ascertain the parameters governing disease
transmission. The unprecedented spread, and uncertain zoonotic potential of
chronic wasting disease (CWD), a contagious epidemic among deer, elk, and other
cervids, is of particular concern. Here we demonstrate that naturally occurring
primary structural differences in cervid PrPs differentially impact the
efficiency of intra- and interspecies prion transmission. Our results not only
deliver new information about the role of primary structural variation on prion
susceptibility, but also provide functional support to a mechanism in which
plasticity of a tertiary structural epitope governs prion protein conversion and
intra- and inter-species susceptibility to prions.-

PO-039: A comparison of scrapie and chronic wasting disease in white-tailed
deer
Justin Greenlee, Jodi Smith, Eric Nicholson US Dept. Agriculture;

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.

This highlights the facts that
1) prior to the onset of clinical signs PrPSc is widely distributed in the
CNS and lymphoid tissues and
2) currently used diagnostic methods are sufficient to detect PrPSc prior
to the onset of clinical signs.
The results of this study suggest that there are many similarities in the
manifestation of CWD and scrapie in white-tailed deer 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

IHC and WB. Tissues with PrPSc immunoreactivity included brain, tonsil,
retropharyngeal and mesenteric lymph nodes, hemal node, Peyer’s patches, and
spleen. While two WB patterns have been detected in brain regions of deer
inoculated by the natural route, unlike the IC inoculated deer, the pattern
similar to the scrapie inoculum predominates.

In Objective 1, Assess cross-species transmissibility of transmissible
spongiform encephalopathies (TSEs) in livestock and wildlife, numerous
experiments assessing the susceptibility of various TSEs in different host
species were conducted. Most notable is deer inoculated with scrapie, which
exhibits similarities to chronic wasting disease (CWD) in deer suggestive of
sheep scrapie as an origin of CWD.

4. Accomplishments
1. Deer inoculated with domestic isolates of sheep scrapie.
Scrapie-affected deer exhibit 2 different patterns of disease associated prion
protein. In some regions of the brain the pattern is much like that observed for
scrapie, while in others it is more like chronic wasting disease (CWD), the
transmissible spongiform encephalopathy typically associated with deer.
his work conducted by ARS scientists at the National Animal Disease Center,
Ames, IA suggests that an interspecies transmission of sheep scrapie to deer may
have been the origin of CWD. This is important for husbandry practices with both
captive deer, elk and sheep for farmers and ranchers attempting to keep their
herds and flocks free of CWD and scrapie.

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.

DEFRA U.K. What is the risk of Chronic Wasting Disease CWD being introduced
into Great Britain? A Qualitative Risk Assessment October 2012
==================================
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.
=================================
Discussion: The C, L and H type BSE cases in Canada exhibit molecular
characteristics similar to those described for classical and atypical BSE cases
from Europe and Japan. *** This supports the theory that the importation of BSE
contaminated feedstuff is the source of C-type BSE in Canada. *** It also
suggests a similar cause or source for atypical BSE in these countries. ***

Susceptibility of UK red deer (Cervus alaphus elaphus) to oral BSE
transmission Project Code: M03024
02/08/2011
The project confirmed that U.K red deer are susceptible to both oral and
intra-cerebral inoculation with the cattle BSE agent. Six clinically positive
(from 26-42 months post inoculation) i.c inoculated and one (56 months post
inoculation) orally dosed deer that tested positive for TSE by
immunohistochemistry and Western blotting using several primary antibodies
demonstrated widespread accumulation of disease specific prion protein in the
central nervous system, peripheral nervous system and enteric nervous system but
none in lymphoreticular system. All showed several brain sites positive for
disease specific prion protein and presented immunohistochemistry and Western
blotting phenotypes with similarities to BSE in sheep, goats and cattle but
unlike those seen in chronic wasting disease (CWD) in elk or scrapie in sheep.
The vacuolar pathology and distribution of disease specific prion protein in red
deer resembled that of CWD in most major respects however we have shown that BSE
can be clearly differentiated from CWD by existing immunohistochemical and
biochemical methods that are in routine use. The knowledge gained as a result of
this work will permit rapid and accurate diagnosis should a TSE ever be detected
in European red deer and will also enable effective disease control methods to
be quickly put in place.

Keywords: chronic wasting disease, transmission, transgenic mouse, bovine
prion protein
Background. CWD is a disease affecting wild and farmraised cervids in North
America. Epidemiological studies provide no evidence of CWD transmission to
humans. Multiple attempts have failed to infect transgenic mice expressing human
PRNP gene with CWD. The extremely low efficiency of PrPCWD to convert normal
human PrPC in vitro provides additional evidence that transmission of CWD to
humans cannot be easily achieved. However, a concern about the risk of CWD
transmission to humans still exists. This study aimed to establish and
characterize an experimental model of CWD in TgSB3985 mice with the following
attempt of transmission to TgHu mice.
Materials and Methods. TgSB3985 mice and wild-type FVB/ NCrl mice were
intracranially injected with 1% brain homogenate from a CWD-infected Tga20 mouse
(CWD/Tga20). TgSB3985 and TgRM (over-expressing human PrP) were similarly
injected with 5% brain homogenates from CWD-infected white-tailed deer (CWD/WTD)
or elk (CWD/Elk). Animals were observed for clinical signs of neurological
disease and were euthanized when moribund. Brains and spleens were removed from
all mice for PrPCWD detection by Western blotting (WB). A histological analysis
of brains from selected animals was performed: brains were scored for the
severity of spongiform change, astrogliosis, and PrPCWD deposition in ten brain
regions.
Results. Clinical presentation was consistent with TSE. More than 90% of
TgSB3985 and wild-type mice infected with CWD/Tga20, tested positive for PrPres
in the brain but only mice in the latter group carried PrPCWD in their spleens.
We found evidence for co-existence or divergence of two CWD/ Tga20 strains based
on biochemical and histological profiles. In TgSB3985 mice infected with CWD-elk
or CWD-WTD, no animals tested positive for PrPCWD in the brain or in the spleen
by WB. However, on neuropathological examination we found presence of amyloid
plaques that stained positive for PrPCWD in three CWD/WTD- and two
CWD/Elk-infected TgSB3985 mice. The neuropathologic profiles in CWD/WTD- and
CWD/Elkinfected mice were similar but unique as compared to profiles of BSE,
BSE-H or CWD/Tg20 agents propagated in TgSB3985 mice. None of CWD-infected TgRM
mice tested positive for PrPCWD by WB or by immunohistochemical detection.
Conclusions. To our knowledge, this is the first established experimental
model of CWD in TgSB3985. We found evidence for co-existence or divergence of
two CWD strains adapted to Tga20 mice and their replication in TgSB3985 mice.
Finally, we observed phenotypic differences between cervid-derived CWD and
CWD/Tg20 strains upon propagation in TgSB3985 mice. Further studies are underway
to characterize these strains.

CWD to cattle figures CORRECTION
Greetings,
I believe the statement and quote below is incorrect ;
"CWD has been transmitted to cattle after intracerebral inoculation,
although the infection rate was low (4 of 13 animals [Hamir et al. 2001]). This
finding raised concerns that CWD prions might be transmitted to cattle grazing
in contaminated pastures."
Please see ;
Within 26 months post inoculation, 12 inoculated animals had lost weight,
revealed abnormal clinical signs, and were euthanatized. Laboratory tests
revealed the presence of a unique pattern of the disease agent in tissues of
these animals. These findings demonstrate that when CWD is directly inoculated
into the brain of cattle, 86% of inoculated cattle develop clinical signs of the
disease.
" although the infection rate was low (4 of 13 animals [Hamir et al.
2001]). "
shouldn't this be corrected, 86% is NOT a low rate. ...

Mule deer, white-tailed deer, and elk have been reported to develop CWD. As
the only prion disease identified in free-ranging animals, CWD appears to be far
more communicable than other forms of prion disease. CWD was first described in
1967 and was reported to be a spongiform encephalopathy in 1978 on the basis of
histopathology of the brain. Originally detected in the American West, CWD has
spread across much of North America and has been reported also in South Korea.
In captive populations, up to 90% of mule deer have been reported to be positive
for prions (Williams and Young 1980). The incidence of CWD in cervids living in
the wild has been estimated to be as high as 15% (Miller et al. 2000). The
development of transgenic (Tg) mice expressing cervid PrP, and thus susceptible
to CWD, has enhanced detection of CWD and the estimation of prion titers
(Browning et al. 2004; Tamgüney et al. 2006). Shedding of prions in the feces,
even in presymptomatic deer, has been identified as a likely source of infection
for these grazing animals (Williams and Miller 2002; Tamgüney et al. 2009b). CWD
has been transmitted to cattle after intracerebral inoculation, although the
infection rate was low (4 of 13 animals [Hamir et al. 2001]). This finding
raised concerns that CWD prions might be transmitted to cattle grazing in
contaminated pastures.

Dear Terry Singeltary,
Thank you for your correspondence regarding the review article Stanley
Prusiner and I recently wrote for Cold Spring Harbor Perspectives. Dr. Prusiner
asked that I reply to your message due to his busy schedule. We agree that the
transmission of CWD prions to beef livestock would be a troubling development
and assessing that risk is important. In our article, we cite a peer-reviewed
publication reporting confirmed cases of laboratory transmission based on
stringent criteria. The less stringent criteria for transmission described in
the abstract you refer to lead to the discrepancy between your numbers and ours
and thus the interpretation of the transmission rate. We stand by our assessment
of the literature--namely that the transmission rate of CWD to bovines appears
relatively low, but we recognize that even a low transmission rate could have
important implications for public health and we thank you for bringing attention
to this matter. Warm Regards, David Colby -- David Colby, PhDAssistant Professor

never say never when it comes to TSE prion disease.
85%+ of all human TSE prion disease i.e. sporadic CJD’s, have never been
proven scientifically to be of any spontaneous nature. not one single case.
sporadic CJDs simply mean unknown to date.
all iatrogenic CJD is, is sporadic cjd, until route and source of said
iatrogenic event took place, documented, and put in the academic/public domain,
and that vary rarely happens. any human TSE from any other species might just
look like any of the sub-types of the sporadic CJD’s. there has already been
documentation of other animals TSE prion disease related very closely to some
sub-types of CJD, i.e. atypical BSE, Scrapie, and atypical Nor-98 Scrapie.

MY point, if there was a horizontal lateral transmission possibility from
animal to man, with the surveillance for both human and animal TSE prion disease
in the USA, in my honest opinion, they would never know it, and the only few
cases that have been documented, could be a direct result of horizonatl lateral
transmission, or not, just a happenstance of bad luck, a chance happening. so,
in my opinion, we cannot rule anything out.
the USA does not even test cats or dogs for TSE prion disease, and they
have been used in pet food, along with other animal carcasses. in fact, it is
still legal to take a deer from a cwd endemic area, and use it in animal feed.
only thing you cannot use, is a CWD positive deer. don’t believe me, see ;
> 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.
but, when felines get a TSE prion disease, it’s Feline Spongiform
Encephalopathy i.e. FSE, there is one documented case of sporadic CJD in a man
and his cat. ...just saying.

Simultaneous occurrence of spongiform encephalopathy in a man and his cat

We report the simultaneous occurrence of sporadic CJD in a man and a new
variety of FSE in his cat.
snip...
This study shows a spatio-temporal association between human and feline
prion diseases. The clinical features of the cat were different from previously
reported cases of FSE which were characterised by gradual onset of behavioural
changes preceding locomotor dysfunction and ataxia.5 Neuropathological changes
were also at variance with the diffuse spongiosis and vacuolation of brainstem
neurons, seen in FSE.5 The synaptic pattern of PrP deposition, similar in the
cat and in the patient, was atypical for a BSE-related condition. Evidence of a
new type of FSE was further provided by the detection of a type-1 PrPres, other
than the BSE-associated type 4.2 Taken together, our data suggest that the same
agent strain of sporadic CJD was involved in the patient and in his cat.
It is unknown whether these TSE occurred as the result of horizontal
transmission in either direction, infection from an unknown common source, or
the chance occurrence of two sporadic forms.

Greetings list members,
ODD that some FELINE in Italy seem to have this same or maybe very similar
phenotype of TSE;
In October 1998 the simultaneous occurrence of spongiform encephalopathy in
a man and his pet cat was reported. The report from Italy noted that the cat did
not display the same clinical features as FSE cases previously seen. Indeed, the
presence of a new type of FSE was suggested. The man was diagnosed as having
sporadic CJD, and neither case (man nor cat) appeared to be affected by a
BSE-related condition.
Case‐to‐case transmission in humans: case reports and series in which
spread through everyday human contact is suggested
There are six reports in which this possible mode of transmission is
considered. The most recent is that of a couple from the USA who had been
married for 30 years.47 The husband died at age 53. He had no relevant family
history, but had had a rotator cuff repair one year before disease onset. His
wife developed symptoms four and half years after her husband's death. She was
morbidly obese and had had a previous hysterectomy, hernia repair and
cholecystectomy. Both occasionally ate brains in the form of ‘kizka’, a type of
sausage.
Immunocytochemistry confirmed pathogenic prion protein deposition in brain
tissue from both husband and wife. Full sequencing of the open reading frame of
the PRNP failed to demonstrate any pathogenic mutations.
Another suspected conjugal case has recently been shown not to be CJD. The
histopathological specimens did not stain for prion protein despite the
microscopic appearance of spongiform change.48
Sporadic CJD has been described in two co‐workers who shared a school wing
for 9 months.49 The first was a 48‐year‐old Californian‐born man of Hispanic
American descent who had had a traumatic leg amputation at age 23, but was
otherwise well. The second was a 48‐year‐old Chilean‐born male who had a blood
transfusion 6 months before onset of symptoms, and was known to eat lambs'
brains. The first patient developed symptoms 5 months after the last contact
with his colleague and was confirmed to have spCJD 2 months after this. The
second patient developed symptoms months later and died 9 months after the last
contact with his colleague.
An English woman, who died of CJD, histologically confirmed at post mortem,
was known to have contact with several affected members of a family with
familial CJD and was related to them by marriage.39 She had known one of the
family, who later died of CJD and had afternoon tea with her at family
gatherings, twice a year, for 20 years, as well as visiting in her final
illness. The woman herself died 12 years later.
There is another similar case of probable CJD, reported in a Chilean woman
who died 13 years after contact with a family with familial CJD. No details of
contact are given.
A third case of death from CJD in someone related in marriage to a family
with familial CJD has been reported in France, in a Tunisian family. No details
are given with regards to family history or contact.21
What is notable about these last three incidents of supposed infection by
social contact is that all have occurred in association with familial CJD.
Although these patients were not known to have been genetically related to their
spouses, the possibility that they came from the same gene pool cannot be
dismissed.

Creutzfeldt-Jakob disease in a husband and wife
A 53-year-old man died of sporadic Creutzfeldt-Jakob disease (CJD) after a
1.5-year clinical course. Four and a half years later, his then 55-year-old
widow died from CJD after a 1-month illness. Both patients had typical clinical
and neuropathologic features of the disease, and pathognomonic
proteinase-resistant amyloid protein ("prion" protein, or PrP) was present in
both brains. Neither patient had a family history of neurologic disease, and
molecular genetic analysis of their PrP genes was normal. No medical, surgical,
or dietary antecedent of CJD was identified; therefore, we are left with the
unanswerable alternatives of human-to-human transmission or the chance
occurrence of sporadic CJD in a husband and wife.

*** 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.

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.

***********CJD REPORT 1994 increased risk for consumption of veal and
venison and lamb***********
CREUTZFELDT JAKOB DISEASE SURVEILLANCE IN THE UNITED KINGDOM THIRD ANNUAL
REPORT AUGUST 1994
Consumption of venison and veal was much less widespread among both cases
and controls. For both of these meats there was evidence of a trend with
increasing frequency of consumption being associated with increasing risk of
CJD. (not nvCJD, but sporadic CJD...tss)
These associations were largely unchanged when attention was restricted to
pairs with data obtained from relatives. ...
Table 9 presents the results of an analysis of these data.
There is STRONG evidence of an association between ‘’regular’’ veal eating
and risk of CJD (p = .0.01).
Individuals reported to eat veal on average at least once a year appear to
be at 13 TIMES THE RISK of individuals who have never eaten veal.
There is, however, a very wide confidence interval around this estimate.
There is no strong evidence that eating veal less than once per year is
associated with increased risk of CJD (p = 0.51).
The association between venison eating and risk of CJD shows similar
pattern, with regular venison eating associated with a 9 FOLD INCREASE IN RISK
OF CJD (p = 0.04).
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).
snip...
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).
snip...
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 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.

*** We hypothesize that both BSE prions and CWD prions passaged through
felines will seed human recPrP more efficiently than BSE or CWD from the
original hosts, evidence that the new host will dampen the species barrier
between humans and BSE or CWD. The new host effect is particularly relevant as
we investigate potential means of trans-species transmission of prion disease.

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.

Domestic and nondomestic cats have been shown to be susceptible to feline
spongiform encephalopathy (FSE), almost certainly caused by consumption of
bovine spongiform encephalopathy (BSE)-contaminated meat. Because domestic and
free-ranging nondomestic felids scavenge cervid carcasses, including those in
areas affected by chronic wasting disease (CWD), we evaluated the susceptibility
of the domestic cat (Felis catus) to CWD infection experimentally. Cohorts of 5
cats each were inoculated either intracerebrally (IC) or orally (PO) with
CWD-infected deer brain. At 40 and 42 mo post-inoculation, two IC-inoculated
cats developed signs consistent with prion disease, including a stilted gait,
weight loss, anorexia, polydipsia, patterned motor behaviors, head and tail
tremors, and ataxia, and progressed to terminal disease within 5 mo. Brains from
these two cats were pooled and inoculated into cohorts of cats by IC, PO, and
intraperitoneal and subcutaneous (IP/SC) routes. Upon subpassage, feline-adapted
CWD (FelCWD) was transmitted to all IC-inoculated cats with a decreased
incubation period of 23 to 27 mo. FelCWD was detected in the brains of all the
symptomatic cats by western blotting and immunohistochemistry and abnormalities
were seen in magnetic resonance imaging, including multifocal T2 fluid
attenuated inversion recovery (FLAIR) signal hyper-intensities, ventricular size
increases, prominent sulci, and white matter tract cavitation. Currently, 3 of 4
IP/SQ and 2 of 4 PO inoculared cats have developed abnormal behavior patterns
consistent with the early stage of feline CWD.
*** These results demonstrate that CWD can be transmitted and adapted to
the domestic cat, thus raising the issue of potential cervid-to- feline
transmission in nature.

Greetings USDA/APHIS et al,
I kindly would like to comment on Docket No. 00-108-10 Chronic Wasting
Disease Herd Certification Program and Interstate Movement of Farmed or Captive
Deer, Elk, and Moose; Program Standards.
I believe, and in my opinion, and this has been proven by scientific facts,
that without a validated and certified test for chronic wasting disease cwd,
that is 100% sensitive, and in use, any voluntary effort will be futile. the
voluntary ban on mad cow feed and SRMs have failed terribly, the bse mad cow
surveillance program has failed terribly, as well as the testing for bse tse
prion in cattle, this too has failed terrible. all this has been proven time and
time again via OIG reports and GOA reports.
I believe that until this happens, 100% cwd testing with validated test,
ALL MOVEMENT OF CERVIDS BETWEEN STATES MUST BE BANNED, AND THE BORDERS CLOSED TO
INTERSTATE MOVEMENT OF CERVIDS. there is simply to much at risk.
In my opinion, and the opinions of many scientists and DNR officials, that
these so called game farms are the cause of the spreading of chronic wasting
disease cwd through much negligence. the game farms in my opinion are not the
only cause, but a big factor. I kindly wish to submit the following to show what
these factors are, and why interstate movement of cervids must be banned.

FSIS, USDA, REPLY TO SINGELTARY
Transmissible Spongiform Encephalopathy TSE Prion Disease North America
2014
Transmissible Spongiform Encephalopathy TSE Prion Disease have now been
discovered in a wide verity of species across North America. typical C-BSE,
atypical L-type BASE BSE, atypical H-type BSE, atypical H-G BSE, of the bovine,
typical and atypical Scrapie strains, in sheep and goats, with atypical Nor-98
Scrapie spreading coast to coast in about 5 years. Chronic Wasting Disease CWD
in cervid is slowly spreading without any stopping it in Canada and the USA and
now has mutated into many different strains. Transmissible Mink Encephalopathy
TME outbreaks. These Transmissible Spongiform Encephalopathy TSE Prion Disease
have been silently mutating and spreading in different species in North America
for decades.
The USDA, FDA, et al have assured us of a robust Triple BSE TSE prion
Firewall, of which we now know without a doubt, that it was nothing but ink on
paper. Since the 1997 mad cow feed ban in the USA, literally tons and tons of
banned mad cow feed has been put out into commerce, never to return, as late as
December of 2013, serious, serious breaches in the FDA mad cow feed ban have
been documented. The 2004 enhanced BSE surveillance program was so flawed, that
one of the top TSE prion Scientist for the CDC, Dr. Paul Brown stated ; Brown,
who is preparing a scientific paper based on the latest two mad cow cases to
estimate the maximum number of infected cows that occurred in the United States,
said he has "absolutely no confidence in USDA tests before one year ago" because
of the agency's reluctance to retest the Texas cow that initially tested
positive.
see ;
The BSE surveillance and testing have also been proven to be flawed, and
the GAO and OIG have both raised serious question as to just how flawed it has
been (see GAO and OIG reports). North America has more documented TSE prion
disease, in different documented species (excluding the Zoo BSE animals in the
EU), then any other place on the Globe. This does not include the very
likelihood that TSE prion disease in the domestic feline and canine have been
exposed to high doses of the TSE prion disease vid pet food. To date, it’s still
legal to include deer from cwd zone into pet food or deer food. Specified Risk
Material i.e. SRM bans still being breach, as recently as just last month.
nvCJD or what they now call vCJD, another case documented in Texas last
month, with very little information being released to the public on about this
case? with still the same line of thought from federal officials, ‘it can’t
happen here’, so another vCJD blamed on travel of a foreign animal disease from
another country, while ignoring all the BSE TSE Prion risk factors we have here
in the USA and Canada, and the time that this victim and others, do spend in the
USA, and exposed to these risk factors, apparently do not count in any way with
regard to risk factor. a flawed process of risk assessment.
sporadic CJD, along with new TSE prion disease in humans, of which the
young are dying, of which long duration of illness from onset of symptoms to
death have been documented, only to have a new name added to the pot of prion
disease i.e. sporadic GSS, sporadic FFI, and or VPSPR. I only ponder how a
familial type disease could be sporadic with no genetic link to any family
member? when the USA is the only documented Country in the world to have
documented two different cases of atypical H-type BSE, with one case being
called atypical H-G BSE with the G meaning Genetic, with new science now showing
that indeed atypical H-type BSE is very possible transmitted to cattle via oral
transmission (Prion2014). sporadic CJD and VPSPR have been rising in Canada,
USA, and the UK, with the same old excuse, better surveillance. You can only use
that excuse for so many years, for so many decades, until one must conclude that
CJD TSE prion cases are rising. a 48% incease in CJD in Canada is not just a
blip or a reason of better surveillance, it is a mathematical rise in numbers.
More and more we are seeing more humans exposed in various circumstance in the
Hospital, Medical, Surgical arenas to the TSE Prion disease, and at the same
time in North America, more and more humans are becoming exposed to the TSE
prion disease via consumption of the TSE prion via deer and elk, cattle, sheep
and goats, and for those that are exposed via or consumption, go on to further
expose many others via the iatrogenic modes of transmission of the TSE prion
disease i.e. friendly fire. I pondered this mode of transmission via the victims
of sporadic FFI, sporadic GSS, could this be a iatrogenic event from someone
sub-clinical with sFFI or sGSS ? what if?
Two decades have passed since Dr. Ironside first confirmed his first ten
nvCJD victims in 1995. Ten years later, 2005, we had Dr. Gambetti and his first
ten i.e. VPSPR in younger victims. now we know that indeed VPSPR is
transmissible. yet all these TSE prion disease and victims in the USA and Canada
are being pawned off as a spontaneous event, yet science has shown, the
spontaneous theory has never been proven in any natural case of TSE prion
disease, and scientist have warned, that they have now linked some sporadic CJD
cases to atypical BSE, to atypical Scrapie, and to CWD, yet we don’t here about
this in the public domain. We must make all human and animal TSE prion disease
reportable in every age group, in ever state and internationally, we must have a
serious re-evaluation and testing of the USA cattle herds, and we must ban
interstate movement of all cervids. Any voluntary effort to do any of this will
fail. Folks, we have let the industry run science far too long with regards to
the TSE prion disease. While the industry and their lobbyist continues to funnel
junk science to our decision policy makers, Rome burns. ...end

Approximately 4,200 fawns, defined as deer under 1 year of age, were
sampled from the eradication zone over the last year. The majority of fawns
sampled were between the ages of 5 to 9 months, though some were as young as 1
month.
*** Two of the six fawns with CWD detected were 5 to 6 months old.
All six of the positive fawns were taken from the core area of the CWD
eradication zone where the highest numbers of positive deer have been
identified.

Conclusion. CWD prions (as inferred by prion seeding activity by RT-QuIC)
are shed in urine of infected deer as early as 6 months post inoculation and
throughout the subsequent disease course. Further studies are in progress
refining the real-time urinary prion assay sensitivity and we are examining more
closely the excretion time frame, magnitude, and sample variables in
relationship to inoculation route and prionemia in naturally and experimentally
CWD-infected cervids.
