Identification of a Streptococcus agalactiae serotype III subtype 4 clone in association with adult invasive disease in Hong Kong.
Characterization of Streptococcus agalactiae serotype III isolates revealed a subtype 4 clone that has an indistinguishable pulsed-field gel electrophoresis pattern and possesses a C-alpha protein, IS1381, and a novel sequence type (ST), ST 283, by multilocus sequence tagging. This clone was significantly associated with diseases caused by invasive strains from nonpregnant adults (P <or= 0.01, chi-square test) and was not present in the genital tracts of pregnant mothers.
