Abstract
The susceptibility of sheep to classical scrapie and bovine spongiform encephalopathy (BSE) is mainly influenced by prion protein (PrP) polymorphisms A136V, R154H, and Q171R, with the ARR allele associated with significantly decreased susceptibility. Here we report the protective effect of the amino acid substitution M137T, I142K, or N176K on the ARQ allele in sheep experimentally challenged with either scrapie or BSE. Such observations suggest the existence of additional PrP alleles that significantly decrease the susceptibility of sheep to transmissible spongiform encephalopathies, which may have important implications for disease eradication strategies.Entities:
