    PRION 2014 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.

    Governor Nixon Missouri Urged to VETO Legislation turning over captive shooting pens to USDA



    snip...



    PLEASE WATCH THIS VIDEO OF A CAPTIVE SHOOTING PEN HUNT.



    THIS IS NOT HUNTING FOLKS, THIS IS JUST SLAUGHTERING A DEFENSELESS ANIMAL, AND HAVING TO PROP IT UP TO DO THAT $$$



    Michigan 2005 237 captive shooting pens not in compliance



    March 2005 DNR Audit



    37 % or 237 captive pens not in compliance.



    96% that died were not tested for CWD, as was required.



    700 captive pens had inadequate fencing.



    tranquilizing target deer...



    Measuring antlers to verify scores for record book.



    Scooping up with front in loading tractor, and dumping into small 3 to 5 acre pen to be shot for up to $20,000.00



    how did the fix the problem, turned the DNR over to the USDA et al, problem solved...

    According to Wisconsin’s White-Tailed Deer Trustee Dr. James Kroll, people who call for more public hunting opportunities are “pining for socialism.”



    He further states, “(Public) Game management is the last bastion of communism.”



    “Game Management,” says James Kroll, driving to his high-fenced, two-hundred-acre spread near Nacogdoches, “is the last bastion of communism.”



    Kroll, also known as Dr. Deer, is the director of the Forestry Resources Institute of Texas at Stephen F. Austin State University, and the “management” he is referring to is the sort practiced by the State of Texas.



    The 55-year-old Kroll is the leading light in the field of private deer management as a means to add value to the land. His belief is so absolute that some detractors refer to him as Dr. Dough, implying that his eye is on the bottom line more than on the natural world.



    Kroll, who has been the foremost proponent of deer ranching in Texas for more than thirty years, doesn’t mind the controversy and certainly doesn’t fade in the heat. People who call for more public lands are “cocktail conservationists,” he says, who are really pining for socialism. He calls national parks “wildlife ghettos” and flatly accuses the government of gross mismanagement. He argues that his relatively tiny acreage, marked by eight-foot fences and posted signs warning off would-be poachers, is a better model for keeping what’s natural natural while making money off the land.



    snip...



    What does this all mean?



    My initial reaction, which is one that I predicted when Kroll was named to the state’s deer trustee position, is that his team’s final recommendations — if implemented — will be heavily skewed toward the state’s larger landowners (500+ acres) and folks who own small parcels in areas comprised mostly of private land. It is also my prediction that the final recommendations (again, if implemented) will do little, if anything, to improve deer herds and deer hunting on Wisconsin’s 5.7 million acres of public land. Where does this leave the public-land hunter? “It will suck to be you,” said one deer manager who asked to remain anonymous out of fear for his job. “The resources and efforts will go toward improving the private land sector. This is all about turning deer hunting away from the Public Land Doctrine and more toward a European-style of management — like they have in Texas.”

    TEXAS CHRONIC WASTING DISEASE CWD Four New Positives Found in Trans Pecos



    http://chronic-wasting-disease.blogspot.com/2013/02/texas-chronic-wasting-disease-cwd-four.html



    spreading cwd around...tss



    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



    Hyun-Joo Sohn, Yoon-Hee Lee, Min-jeong Kim, Eun-Im Yun, Hyo-Jin Kim, Won-Yong Lee, Dong-Seob Tark, In- Soo Cho, Foreign Animal Disease Research Division, National Veterinary Research and Quarantine Service, 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.
