Phylogenetic analysis of the amino acid sequence of 25 new complete VP1, VP2 and VP3 sequences from Anhui (AN), Hunan (HU) and Jiangsu (JS) provinces, China and 29 relevant VP1, VP2 and VP3 sequences currently available in GenBank. Values ≥70 are indicated on the branches (as percentages). Sequences from the present study (colored closed symbols) are named as follows PP-China where PP is the area of origin. Sequences from GenBank were given the country name followed by accession number. The two major groups were identified as I and II.
