Fig. 3.
Phylogenetic trees generated by neighbor-joining method based on a the minor parent region estimated with SIMPLOT and RDP software (nt 100–389) and b the major parent region (concatenated alignment of nt 1–99 and nt 390–462). Chilean strains were compared with twenty-five PCV2 reference strains. GenBank accession numbers and country of origin are specified. Genotypes are indicated with straight brackets. Discordant clustering patterns of potential Chilean recombinant strains with different genotypes are observed (◆)
