Phylogenetic tree constructed by alignment of the348- nt nucleotide sequence of ORF2 from isolates in this study and references of other animal and human HEV isolates, using the neighbor- joining method and evaluated using the interior branch test method with Mega 4 software. Percent bootstrap support is indicated at each node. GenBank accession no., source and country of origin are indicated. The isolates in this study were marked with solid triangle. Avian HEV strain is included as outgroup.
