Phylogenetic analysis of the full-length ORF2 gene sequences of PCV3 based on 200 strains: 38 strains from this study indicated by black triangles and 162 strains downloaded from GenBank with accession number and strain information listed in Additional file 1: Table S1. All PCV3 strains could be divided into three groups, PCV3a (blue), PCV3b (yellow) and PCV3c (green). The tree was constructed by the neighbor-joining method in MEGA 7.0 software (p-distance model; 1000 bootstraps; only bootstrap scores above 50 are shown)
