Fig. 2.

Median-joining haplotype network for PCV3. Circles correspond to haplotypes and the size of the circles is proportional to the frequency of the haplotypes in the network. Triangles correspond to the median vectors. The number of substitutions is represented in the connections between the haplotypes. Numbers close to the lines correspond to the numbers of transitions and crossings between the haplotypes. The three major haplotypes were haplotype H1 includes sequences from USA, China, Brazil, South Korea, Colombia, Denmark, Spain, Japan, UK, and Thailand; haplotype H3 includes sequences from China, Brazil, Korea, USA, and UK; haplotype H7 includes sequences from China and Brazil. The information about each sequence (GenBank accession number, year and country of origin) is described in Supplementary File 1
