Phylogenetic tree of the full-length PCV-3 genome using the neighbor-joining method. Bootstrap values were determined with 1000 replicates, and the evolutionary distances were computed using the Tamura 3 parameter model. Evolutionary analyses were conducted with MEGA 6.0 software [29]. The three Brazilian PCV-3 field strains from free-living wild boars are labeled with a solid black triangle. The sequences of PCV-1 and PCV-2 were used as outgroups.
