*GBS, group B Streptococcus; PFGE, pulsed-field gel electrophoresis. †Early-onset, patient age birth–6 days or mother during peripartum period; late-onset, patient age 7–180 days. ‡Multilocus sequence type of 7 housekeeping genes (adhP, pheS, atr, glnA, sdhA, glcK, tkt). §From http://pubmlst.org/sagalactiae database. ¶Determined by eBurst analysis (25).
