Cross-Species Transmission of Prion Diseases

Although there are no known ways to cure transmissible spongiform encephalopathy (TSE) diseases, scientists around the world are working to develop treatments. Experiments have demonstrated that species once thought to be resistant to certain TSE strains can be life-long carriers of the infection without ever becoming sick.

Scientists at NIAID's Rocky Mountain Laboratories also are investigating whether chronic wasting disease (CWD) can be transmitted from deer or elk to other species after eating brain matter from deer or elk that are infected with CWD. That knowledge would provide valuable insight into whether this disease could possibly be transmitted to humans.​​
