Genome map of S. agalactiae indicating loci of interest. The relative positions of housekeeping genes characterized in the MLST scheme (pheS, atr, tkt, glnA, sdhA, glcK, and adhP), genes identified for surface protein gene profiling (same relative positions for bca, alp2, alp3, alp4, rib, or eps), bac, regions characterized for pilus island profiling PI-1 and PI-2 (same relative positions for PI-2a or PI-2b), and the capsular locus region are depicted. Numbers inside the circle represent the scale in megabases.
