Additionally, a different phenotype of scrapie (atypical scrapie) was reported in 1998. The prevalence of these atypical diseases is low and suggests the possibility that they are spontaneous forms of prion diseases. Despite their unknown origin, the transmissibility of these atypical animal prion diseases has been demonstrated read more ...
