Document Summary

Chronic wasting disease is a tse that cannot be transmitted naturally to non-cervids. Transmissible - can be transmitted to other animals. When looking at the brain as a whole you wouldnt be able to tell. Lose normal fear or become aggressive increaed salivation may carry head and ears lowered tremors. Cwd prions are shed in saliva, urine, and feces. Once contaminated, the environment stays infectious for years. Carcass of infected animal is also hazardous to others. Minor changes in behavior increased risk of trauma rough hair coat slowly progressive. Postmortem - test on brainstem or lymph nodes. Ihc test w/ antibodies stained to look at under a microscope to check presence of antigen. Antemortem test- tonsillar and rectal biopsy test using the ihc technology. They will eventually die, but can live slightly longer. Resistant genotypes may be less likely to become infected. There"s no way to really predict the pattern of transmission.
