|CWD found in far West Texas|
If you look hard enough, chances are you are going to find something eventually.
Samples from two mule deer recently taken in far West Texas have been confirmed positive for Chronic Wasting Disease. These are the first cases of CWD detected in Texas deer. Wildlife officials believe the event is currently isolated in a remote part of the state near the New Mexico border.
The Texas Parks and Wildlife Department and the Texas Animal Health Commission implemented regionally-focused deer sample collection efforts after the disease was detected in the Hueco Mountains of New Mexico during the 2011-12 hunting season. With the assistance of cooperating landowners, TPWD, TAHC, and USDA-APHIS-Wildlife Services biologists and veterinarians collected samples from 31 mule deer as part of a strategic CWD surveillance plan designed to determine the geographic extent of New Mexico’s findings. Both infected deer were taken from the Hueco Mountains of northern El Paso and Hudspeth counties.
CWD is a member of the group of diseases called transmissible spongiform encephalopathies (TSEs). Other diseases in this group include scrapie in sheep, bovine spongiform encephalopathy (BSE or mad cow disease) in cattle, and Cruetzfeldt-Jakob disease in humans. CWD among cervids is a progressive, fatal disease that commonly results in altered behavior as a result of microscopic changes made to the brain of affected animals. An animal may carry the disease for years without outward indication, but in the latter stages, signs may include listlessness, lowering of the head, weight loss, repetitive walking in set patterns and a lack of responsiveness. CWD is not known to affect humans.
Tissue samples were initially tested by the Texas Veterinary Medical Diagnostic Laboratory in College Station, with confirmation by the National Veterinary Services Laboratory in Ames, Iowa.
“Now that we have detected CWD in Texas, our primary objective is to contain this disease,” said Carter Smith, TPWD Executive Director. “Working collaboratively with experts in the field we have developed protocols to address CWD and implementation is already under way.”
