Prion gene sequencing in Florida panthers (Puma concolor coryi) suggests no differential susceptibility to transmissible spongiform encephalopathy

Transmissible spongiform encephalopathy, or prion disease, poses a serious threat to wildlife; however, the susceptibility of apex predators is still being assessed. We investigated variation in the prion protein gene in Florida panthers (Puma concolor coryi) and found that admixture from Central American pumas probably introduced a novel, albeit benign, prion allele.
