Prevalence of Streptococcus pneumoniae serotype 6C among invasive and carriage isolates in metropolitan Salvador, Brazil, from 1996 to 2007

Abstract

The newly described Streptococcus pneumoniae serotype 6C accounted for 2.3% (16/709) of meningitis cases and 3.2% (3/95) of nasopharyngeal isolates from healthy individuals in Brazil. The strains were multidrug resistant (18.8%) and genetically diverse. Despite low serotype 6C prevalence, continuous surveillance is necessary to guide vaccine strategies.

PFGE analysis showing serotype 6C isolates recovered from meningitis cases and carriage: Cluster I (black stars) comprised of eight meningitis isolates (nos. 151A, 2A, 708A, 511A, 93A, 510A, 565A and 244A), belonging to ST 3930; Cluster II (white stars), comprised of two meningitis isolates (nos. 286A and 199A) and three 6C NP carriage isolates (nos. 30220, 6052, 30219), belonging to ST 812. The other six isolates are genetic outliers as judged by PFGE-relationships (Sxt, trimethoprim / sulfametoxazole; S, susceptible; NS, non-susceptible).
