THREE KANSAS DEER CONFIRMED POSITIVE IN EARLY STAGES OF CWD TESTING

Posted Feb 09 2012 12:07pm
THREE KANSAS DEER CONFIRMED POSITIVE IN EARLY STAGES OF CWD TESTING



Feb. 9, 2012



Numbers still low; no known threat to humans or livestock



PRATT — The number of cases of chronic wasting disease (CWD) detected in Kansas deer continues to be low and is currently isolated to the northwest part of the state, according to the Shane Hesting, wildlife disease coordinator for the Kansas Department of Wildlife, Parks and Tourism (KDWPT). Samples from three white-tailed bucks taken during this year’s hunting season were confirmed positive for CWD in tests completed last week. Counties where the deer were taken include Wallace (new county of detection), Decatur, and Rawlins. KDWPT will continue testing some vehicle-killed and sick or suspect-looking deer, as well as deer taken with depredation permits, through July 31.



“This season’s testing results bring the total number of confirmed CWD cases in Kansas to 43 since testing began in 1996,” says Hesting. “About 2,400 samples were collected during the 2011-2012 deer seasons, but testing has been slow, and testing kits are continually on back order. We’re about 35 percent done. More importantly, U.S. Department of Agriculture funding will not be available for collecting and testing samples next season. Without federal financial assistance, surveillance will be very limited and less robust.”




Annual testing has been a part of an ongoing effort by KDWPT to monitor the prevalence and spread of CWD. The disease, fatal in wild deer, was first detected in deer taken in Cheyenne County in 2005.




CWD is a member of the group of diseases called transmissible spongiform encephalopathies (TSEs). Other diseases in this group include scrapie in sheep and goats, bovine spongiform encephalopathy (BSE or Mad Cow Disease) in cattle, and Cruetzfeldt-Jakob disease in people. CWD is a progressive, fatal disease that results in small holes developing in the brain, giving it a sponge-like appearance under the microscope. An animal may carry the disease without outward indication, but in the later stages, signs may include decreased interactions with other animals, listlessness, lowering of the head, weight loss, repetitive walking in set patterns, and a lack of response to humans.




“It must be noted that many of the symptoms of CWD are indicative of other diseases,” Hesting explains. “Thus, a sick deer may or may not be infected with CWD. CWD is a serious deer disease but is still rare in Kansas.”




All but three of the 43 positive animals detected since 2005 were asymptomatic, meaning 40 animals did not show any symptoms of CWD at the time of collection. Anyone who discovers a sick or suspect deer should contact the nearest KDWP office.




There is no vaccine or other biological method that prevents CWD. However, there is no evidence that CWD poses a risk to humans or livestock in the natural environment. Still, precautions should be taken. Hunters are advised not to eat meat from animals known to be infected, and common sense precautions are advised when field dressing and processing meat from animals taken in areas where CWD is found. More information on CWD can be found on KDWPT’s website, www.ksoutdoors.com (Hunting/Big Game Information), or at the Chronic Wasting Disease Alliance website, www.cwd-info.org.

TEN KANSAS DEER CONFIRMED POSITIVE IN CWD TESTS


http://chronic-wasting-disease.blogspot.com/2011/03/ten-kansas-deer-confirmed-positive-in.html










>  Can the disease be transfered to cattle and humans ??



CWD has already been transmitted to many cattle in the lab (86% in one study). the oral route would have a much longer incubation period, but we already know that CWD will transmit back to cervids via the oral route, very efficiently. the threat of spreading CWD via close contact, like at feeding grounds is great. every bit of science to date shows this. so to congregate deer together by unnatural means is not smart in my opinion. another fear has come to pass as well, another strain of CWD, yes a second strain. and just recently science has shown that a natural case of BSE has been transmitted to a GOAT.






These findings demonstrate that when CWD is directly inoculated into the brain of cattle, 86% of inoculated cattle develop clinical signs of the disease.

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

UPDATED DATA ON 2ND CWD STRAIN


Wednesday, September 08, 2010


CWD PRION CONGRESS SEPTEMBER 8-11 2010



http://chronic-wasting-disease.blogspot.com/2010/09/cwd-prion-2010.html







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. ...

kindest regards,

Terry S. Singeltary Sr. P.O. Box 42 Bacliff, Texas USA 77518

PLEASE NOTE ON SECOND PASSAGE, ALL CATTLE 100% HAD CONTRACTED CWD ;





When brainstems of CWD-infected cattle were analysed by WB for the presence of PrPres, only three of six samples were found to be positive (Table 1). In contrast, all samples from the midbrain area were positive by this technique (Table 1; Fig. 5). It was noteworthy, however, that both brainstem and midbrain sections of all animals infected with CWD gave positive IHC results (Table 1) and a positive WB was associated with strong IHC labelling. This may indicate that the IHC procedure is more sensitive than the WB method for cattle-passaged CWD.

IN CONFIDENCE

Perceptions of unconventional slow virus diseases of animals in the USA

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 about 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. Whether they were scrapie infected sheep or not is unclear.

Mr R.N. Elmhirst Chairman British Deer Farmers Association Holly Lodge Spencers Lane BerksWell Coventry CV7 7BZ

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.
