Phylogenetic tree depicting genotypic/subgenotypic status of swine and human HEV strains isolated in Shanghai. A) Analyses based on 5 full-length swine and human HEV genomic sequences and 44 ORF2 sequences located between nt 6,104 and nt 6,256 within the HEV SH-SW-zs1 genome [GenBank:EF570133]. B) Analyses based on 16 sequences located between nt 6,360 and nt 6,509 within the HEV SH-SW-zs1 genome. Percent bootstrap support is indicated at each node. For each phylogeny, HEV subtypes were indicated on the outside of the square brackets that define the HEV subtypes. Each branch is labeled with the host of the HEV isolate, GenBank accession number and the year the strain was isolated. Reference sequences are labeled with the prefix RE, the subtype of the sequence, the GenBank accession number and the geographical source.
