Phylogenetic analysis of HEV isolates based on the three reference data sets.

<p>Neighbor-joining trees were produced by using nucleotides of complete genome (data set 1) (A), using of nucleotides concatenated first and second codon sites of ORF1/ORF2 (data set2) (B), using amino acids of concatenated protein sequences of ORF1/ORF2 (data set 3) (C). Bootstraps values (>70) and scale bars are shown.
