*All samples were from naturally infected animals, with the exception of 1 sheep experimentally inoculated with CH1641.

†The PrP genotype reported is expressing the amino acid variants present at the major polymorphic codons described for each species.
‡The Canada isolate was homozygous for lysine at codon 109 and for isoleucine at codon 209 (KK109II209) (GenBank accession no. MH230114).
