shown a 6% incidence in mule deer and 1% incidence in elk (T. Spraker, pers. commun., 1997). Evidence of the etiologic agents is found in brain, spinal cord, and lymph nodes (by using a monoclonal antibody derived from antigens of ovine scrapie). CWD is considered one of the transmissible spongi-form encephalopathies that are potentially transmissible to other species, including humans. The disease has not been reported in elk or deer in the GYA, and no studies have been done on the danger that this disease has for humans.
