goeBURST diagram of the relationships among STs of 66 S. agalactiae isolates. The numbers in the circles indicate the STs, and the numbers near the lines indicate the number of differing alleles between the two connected STs. Putative CCs are identified by an outer dotted frame and correspond to the STs with the highest number of single locus variants.

Abbreviations: CC, clonal complex; ST, sequence type.
