<p>A) MST of 89 MLST allelic profiles of the whole dataset included in this study. The colors are based on the origin of isolation. B) MST of the Peruvian subset that includes 56 strains. The colors are based on the serotyping group. Each circle represents an MLST genotype, and its size is proportional to the number of strains. The numbers along the branch links of MLST genotypes denote the amount of allelic differences.</p
