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 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.

Exotic Meats USA Announces Urgent Statewide Recall of Elk Tenderloin Because It May Contain Meat Derived From An Elk Confirmed To Have CWD

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.
