Streptococcus agalactiae Serotype Ib as an Agent of Meningitis in Two Adult Nonpregnant Women

ABSTRACT Two temporally and geographically clustered cases of meningitis caused by Streptococcus agalactiae expressing the infrequent Ib serotype are reported. Characterization by pulsed-field gel electrophoresis and multilocus sequence typing revealed that the isolates were identical and represented the widely distributed ST10/ST8 lineage associated with serotype Ib.
