Genetic characterization and sequence heterogeneity of a canadian isolate of Swine hepatitis E virus.

ABSTRACT: Swine hepatitis E virus (HEV) is a newly identified potentially zoonotic agent that is possibly transmitted to humans from pigs. Swine HEV is prevalent in pig populations and does not cause abnormal clinical symptoms in infected pigs, further implicating a likelihood of a risk of transmission to humans by normal contact. To date in North America, only one strain of swine HEV (strain US swine) has been fully sequenced. In the present study, we identified a swine HEV isolate from pigs in Canada, designated the Arkell strain, and determined the full length of the genomic sequence. The genome of Canadian strain Arkell consisted of 7,242 nucleotides, excluding the poly(A) tail of at least 15 A residues. The genome contained three open reading frames (ORFs), ORF1, ORF2, and ORF3, which had codin
