Streptococcus agalactiae serotype Ib as an agent of meningitis in two adult nonpregnant women

J Clin Microbiol. 2007 Nov;45(11):3850-2. doi: 10.1128/JCM.01358-07. Epub 2007 Sep 19.


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.
