Phylogenetic analysis based on the VP2 protein sequences of CPV-2 isolates. A phylogenetic tree was constructed based on the complete VP2 protein sequences using the neighbor-joining method with 1000 bootstrap replicates with MEGA 6.0 software package. Solid triangle (▲), circle (●), diamond (◆), and square (■) indicates the CPV-2c, new CPV-2a, new CPV-2b and new CPV-2 strains identified in this study, respectively. Others were retrieved from GenBank. The strains are shown as “strain name”, “accession number” and “country”.
