Chronic Wasting Disease, how does it affect our animals?
Colorado State University researchers are looking at chronic wasting disease (CWD) transmission and prevention.
This illness hurts the brains of elk and deer and has been a big problem in the Colorado/Wyoming area.
Instead of being caused by a virus or a bacterium, the disease appears to be caused by prions. Prions are abnormal proteins that enter a cell and distrupt functioning from there.
Candance Mathiason along with many other researchers and research assistants has been investigating the transmission of CWD through body fluids: blood, saliva, urea, feces, and milk.
They are still investigating the milk, but everything else is a given now. The disease can spread by the animal just being in an environment that hosted the infected animal.
Currently they are testing a vaccine. As of February 16, 2012, only one of the vaccinated animals has shown antibodies.
Vaccinations for prion diseases, or transmissible
spongiform encephalopathies (TSEs), are risky because we are essentially vaccinating an animal against an abnormal protein. If the antibodies attack the normal protein, the vaccination did not perform well.
Instead of the functions of normal proteins, these abnormal proteins on CWD stack up. The nerves cannot communicate and toxins that kill neurons are released.
While we may know more about how CWD works and spreads, a cure or prevention is still in the making.Colorado State University researchers are looking at chronic wasting disease (CWD) transmission and prevention.

CHRONIC WASTING DISEASE CWD WISCONSIN Almond Deer (Buckhorn Flats) Farm Update DECEMBER 2011
> > > The CWD infection rate was nearly 80%, the highest ever in a North American captive herd.
Despite the five year premise plan and site decontamination, The WI DNR has concerns over the bioavailability of infectious prions at this site to wild white-tail deer should these fences be removed. Current research indicates that prions can persist in soil for a minimum of 3 years.
However, Georgsson et al. (2006) concluded that prions that produced scrapie disease in sheep remained bioavailable and infectious for at least 16 years in natural Icelandic environments, most likely in contaminated soil.
Additionally, the authors reported that from 1978-2004, scrapie recurred on 33 sheep farms, of which 9 recurrences occurred 14-21 years after initial culling and subsequent restocking efforts; these findings further emphasize the effect of environmental contamination on sustaining TSE infectivity and that long-term persistence of prions in soils may be substantially greater than previously thought. < < <
