Phylogenetic analysis based on HEV ORF2 (304 nt, the primers not included) showing the genetic relationships between the isolates identified in this study and isolates from across China and other countries. A neighbor-joining tree was constructed with bootstrap values calculated from 1,000 replicates. The isolates used for the comparative analysis were HEV genotype 4 strains CHN-SD-sHEV (KF176351), CHN-XJ-SW13 (GU119961), HE-JA2 (AB220974), KM01 (KJ155502), TW6196E (HQ634346), CHN-XJ-SW33 (GU119960), swCH25 (AY594199), genotype 3 strains swJR-P5 (AB481229), Arkell (AY115488), JBOAR1-Hyo04 (AB189070), genotype 2 strain Mexico (M74506), genotype 1 strain India (AF459438), Madras (X99441), Pakistan (AF185822), SAR55 (M80581), Ugih (D11092), US1 (AF060668), Burma (M73218), and Avian HEV (AY535004).
