Figure 1. Phylogenetic tree (ML) with timeline estimated divergences based on 199 full-length genomes of CPV-2 isolated from 1978 to 2017. Evolutionary clades are indicated as Asia and Western (WT) with their subclades as Asia-I to -IV, and WT-I to -III. The strains are colored according to the CPV genotype. * Represents the CPV strains from this study.
