The tree was constructed by the neighbor joining method with 1000 bootstrap replicates, using MEGA 6.0. The phylogenetic tree was constructed based on the partial ORF2 gene of avian HEV (242 bp) and 30 reference strains found in NCBI. The detailed information of the reference strains are shown in supplementary Table 1. Strains in this study are marked with asterisk (*), while potential novel genotypes reported in other articles are marked with double asterisks (**)
