Figure 1. Phylogenetic analysis of PCV3 cap genes based on the nucleotides sequences. All reference strain sequences included in this study were downloaded from the NCBI GenBank database. The tree was constructed by the maximum-likelihood method using the HKY nucleotide model with invariant sites (+I) and Gamma distributed rates (+G) and 1000 bootstrap replicates. Bootstrap values are indicated for nodes with values >50%. Canadian PCV3 strains are indicated by light orange color.
