<p>Black circles indicate intermediate or unsampled haplotypes, while lines between points represent nucleotide substitutions. Wherever there are more than four substitutions, they are indicated by numbers. Clades K, L, H, I, J are marked to match the corresponding clades in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0077044#pone-0077044-g004" target="_blank">Figure 4</a>. Colored circles and squares indicate haplotypes whose size is proportional to the number of individuals showing that haplotype. Haplotype_7 is represented by 4 clones of Pb1C1; haplotype_14 is represented by 4 clones of Pb1C2 and 7 clones of Pb1C3; haplotype_22 is represented by 5 clones of Pb1C4 and 3 clones of Pb2C1; haplotype_25 is represented by 3 clones of Pb3C1.</p
