Genetic Diversity and Antimicrobial Drug Resistance of Serotype VI Group B Streptococcus, Canada

Abstract

Two genetically dissimilar sequence type 1 clades dominate the serotype VI group B Streptococcus population of strains causing invasive disease in Canada. Isolates of this rare serotype, recovered mainly from adult patients, were all susceptible to penicillin and vancomycin. However, we observed resistance to erythromycin and clindamycin.
