*HEV, hepatitis E virus; ORF, open reading frame; NCR, noncoding region. Boldface indicates percentage identities of amino acid sequences. “Avirulent aHEV” and prototype aHEV are avian HEV isolates from the United States, GenBank accession nos. EF206691 and AM535004, respectively. AaHEV, EaHEV, and CaHEV are avian HEV isolates from Australia, Europe, and China, GenBank accession nos. AM943647, AM943646, and GU954430, respectively.
