WYOMING Deer Hunt Area 132 Near Green River Added to CWD List
Deer Hunt Area 132 Near Green River Added to CWD List
10/23/2012
GREEN RIVER - Chronic wasting disease (CWD), a fatal neurological disease
of deer, elk, and moose, has been discovered in deer hunt area 132.
Green River Wildlife Management Coordinator Mark Zornes said this case
involved a mule deer doe that was collected within a half mile of the Green
River Game and Fish Regional Office because it was emaciated and in poor body
condition. The doe was euthanized and submitted for testing.
“This is the first time we have found CWD in this hunt area,” Zornes said.
“However, the occurrence of CWD in Green River is not a huge surprise. CWD has
been documented in Utah near the Wyoming border, about 40 miles to the
south.”
CWD is not known to be a disease of humans and presents no known public
health significance at this time. Nonetheless, to avoid risk, the Centers for
Disease Control and Prevention recommends that people avoid eating meat from
deer and elk that look sick or that test positive for CWD.
The Game and Fish continues to collect samples through hunter field checks
and at CWD sampling stations. More than 4,000 CWD samples are collected annually
throughout the state.
“There are no methods that have been proven effective in stopping the
expansion of CWD, although a number of things have been tried in other states,”
said Eric Keszler, Game and Fish assistant Services Division chief. “Recent
research in Wisconsin and Colorado has shown that large-scale culling of animals
is ineffective in stopping the spread of the disease or reducing its prevalence.
Currently, the Wyoming Game and Fish Department is monitoring the disease,
conducting various research projects to understand more about CWD, and educating
the public on the presence of the disease and what it means for wildlife and
people. The department is committed to using the best available science to
manage this disease in a manner that makes sense for the wildlife and people of
Wyoming.”

CWD Controversy still stalking elk feedgrounds in Wyoming 2010
Greetings,
This is very serious, please notice that one of the CWD clusters is only 45
miles from ELK feeding grounds in Wyoming, the second elk feeding ground is 98
miles from CWD cluster, and the third elk feeding ground is 130 miles from the
CWD cluster. Common sense tells us we need to stop those feeding grounds, if you
want your Elk to survive. There is no politics or plot against the hunters or
elk about it. read the science please. ...TSS

The constant increase of chronic wasting disease (CWD) incidence in North
America raises a question about their zoonotic potential. A recent publication
showed their transmissibility to new-world monkeys, but no transmission to
old-world monkeys, which are phylogenetically closer to humans, has so far been
reported. Moreover, several studies have failed to transmit CWD to transgenic
mice overexpressing human PrP. Bovine spongiform encephalopathy (BSE) is the
only animal prion disease for which a zoonotic potential has been proven. We
described the transmission of the atypical BSE-L strain of BSE to cynomolgus
monkeys, suggesting a weak cattle-to-primate species barrier. We observed the
same phenomenon with a cattleadapted strain of TME (Transmissible Mink
Encephalopathy). Since cattle experimentally exposed to CWD strains have also
developed spongiform encephalopathies, we inoculated brain tissue from
CWD-infected cattle to three cynomolgus macaques as well as to transgenic mice
overexpressing bovine or human PrP. Since CWD prion strains are highly
lymphotropic, suggesting an adaptation of these agents after peripheral
exposure, a parallel set of four monkeys was inoculated with CWD-infected cervid
brains using the oral route. Nearly four years post-exposure, monkeys exposed to
CWD-related prion strains remain asymptomatic. In contrast, bovinized and
humanized transgenic mice showed signs of infection, suggesting that CWD-related
prion strains may be capable of crossing the cattle-to-primate species barrier.
Comparisons with transmission results and incubation periods obtained after
exposure to other cattle prion strains (c-BSE, BSE-L, BSE-H and cattle-adapted
TME) will also be presented, in order to evaluate the respective risks of each
strain.

Chronic wasting disease (CWD) is a contagious, rapidly spreading
transmissible spongiform encephalopathy (TSE) occurring in cervids in North
America. Despite efficient horizontal transmission of CWD among cervids natural
transmission of the disease to other species has not yet been observed. Here, we
report a direct biochemical demonstration of pathological prion protein PrPTSE
and of PrPTSE-associated seeding activity in skeletal muscles of CWD-infected
cervids. The presence of PrPTSE was detected by Western- and postfixed frozen
tissue blotting, while the seeding activity of PrPTSE was revealed by protein
misfolding cyclic amplification (PMCA). The concentration of PrPTSE in skeletal
muscles of CWD-infected WTD was estimated to be approximately 2000- to
10000-fold lower than in brain tissue. Tissue-blot-analyses revealed that PrPTSE
was located in muscle- associated nerve fascicles but not, in detectable
amounts, in myocytes. The presence and seeding activity of PrPTSE in skeletal
muscle from CWD-infected cervids suggests prevention of such tissue in the human
diet as a precautionary measure for food safety, pending on further
clarification of whether CWD may be transmissible to humans.
CWD has been identified in free-ranging cervids in 15 US states and 2
Canadian provinces and in ≈ 100 captive herds in 15 states and provinces and in
South Korea (Figure 1, panel B). 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).

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.

*** 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 Scrapie by Natural Route of Infection
Jodi D. Smith, Justin J. Greenlee, and Robert A. Kunkle; Virus and Prion
Research Unit, National Animal Disease Center, USDA-ARS Interspecies
transmission studies afford the opportunity to better understand the potential
host range and origins of prion diseases. Previous experiments demonstrated that
white-tailed deer are susceptible to sheep-derived scrapie by intracranial
inoculation. The purpose of this study was to determine susceptibility of
white-tailed deer to scrapie after a natural route of exposure. Deer (n=5) were
inoculated by concurrent oral (30 ml) and intranasal (1 ml) instillation of a
10% (wt/vol) brain homogenate derived from a sheep clinically affected with
scrapie. Non-inoculated deer were maintained as negative controls. All deer were
observed daily for clinical signs. Deer were euthanized and necropsied when
neurologic disease was evident, and tissues were examined for abnormal prion
protein (PrPSc) by immunohistochemistry (IHC) and western blot (WB). One animal
was euthanized 15 months post-inoculation (MPI) due to an injury. At that time,
examination of obex and lymphoid tissues by IHC was positive, but WB of obex and
colliculus were negative. Remaining deer developed clinical signs of wasting and
mental depression and were necropsied from 28 to 33 MPI. Tissues from these deer
were positive for scrapie by IHC and WB. Tissues with PrPSc immunoreactivity
included brain, tonsil, retropharyngeal and mesenteric lymph nodes, hemal node,
Peyer’s patches, and spleen. This work demonstrates for the first time that
white-tailed deer are susceptible to sheep scrapie by potential natural routes
of inoculation. In-depth analysis of tissues will be done to determine
similarities between scrapie in deer after intracranial and oral/intranasal
inoculation and chronic wasting disease resulting from similar routes of
inoculation.

We intracerebrally challenged four species of native North American rodents
that inhabit locations undergoing cervid chronic wasting disease (CWD)
epidemics. The species were: deer mice (Peromyscus maniculatus), white-footed
mice (P. leucopus), meadow voles (Microtus pennsylvanicus), and red-backed voles
(Myodes gapperi). The inocula were prepared from the brains of hunter-harvested
white-tailed deer from Wisconsin that tested positive for CWD. Meadow voles
proved to be most susceptible, with a median incubation period of 272 days.
Immunoblotting and immunohistochemistry confirmed the presence of PrPd in the
brains of all challenged meadow voles. Subsequent passages in meadow voles lead
to a significant reduction in incubation period. The disease progression in
red-backed voles, which are very closely related to the European bank vole (M.
glareolus) which have been demonstrated to be sensitive to a number of TSEs, was
slower than in meadow voles with a median incubation period of 351 days. We
sequenced the meadow vole and red-backed vole Prnp genes and found three amino
acid (AA) differences outside of the signal and GPI anchor sequences. Of these
differences (T56-, G90S, S170N; read-backed vole:meadow vole), S170N is
particularly intriguing due its postulated involvement in "rigid loop" structure
and CWD susceptibility. Deer mice did not exhibit disease signs until nearly 1.5
years post-inoculation, but appear to be exhibiting a high degree of disease
penetrance. White-footed mice have an even longer incubation period but are also
showing high penetrance. Second passage experiments show significant shortening
of incubation periods. Meadow voles in particular appear to be interesting lab
models for CWD. These rodents scavenge carrion, and are an important food source
for many predator species. Furthermore, these rodents enter human and domestic
livestock food chains by accidental inclusion in grain and forage. Further
investigation of these species as potential hosts, bridge species, and
reservoirs of CWD is required.

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
