From: Pilus distribution among lineages of group b streptococcus: an evolutionary and clinical perspective

Figure 5

Gain and loss of pilus islands among GBS sequence types (STs). eBURST analysis was conducted on the MLST allele profiles for all 295 strains. The founding genotype was assigned to the ST that varies from the largest number of STs at a single locus. STs grouped into three main groups bovine strains indicated by red print. The PI profile distribution is indicated by the color of the circle representing each ST. Double locus variants are connected via dashed lines and STs with multiple pilus profiles are connected with orange lines. In cases where the founding genotype had strains with multiple PI profiles, the ST was listed twice. The predicted founding and co-founding genotypes were used to predict acquisition and loss of PIs, as indicated by the grey arrows.
