Tibetan antelope (Rhinopithecus), blue sheep (Pseudois nayauris), and plateau pika (Ochotona curzoniae) are wild animals living on the Qinghai-Tibet Plateau. There have been no reports of naturally occurring transmissible spongioform encephalopathies (TSEs) involving these animals. Furthermore, the PRNP genes have not been described in the literature.
