aGBS, group B streptococcus.
bThe presence of inserted sequences is determined at the three chromosomal locations (see Methods).
cRDP type refers to phylogenetic lineages originally defined by analysis of restriction digest patterns of chromosomal DNA.
dinfB is the highly conserved gene encoding initiation-translation factor IF2.
eST refers to the isolates’ sequence type, based on the alleles of seven housekeeping genes identified by multilocus sequence typing.
