Genomic Analysis of Group B Streptococcus Carriage Isolates From Botswana Reveals Distinct Local Epidemiology and Identifies Novel Strains.

In pregnant people colonized with group B Streptococcus (GBS) in Botswana, we report the presence/expansion of sequence types 223 and 109, a low rate of erythromycin resistance, and 3 novel sequence types. These data highlight the importance of local epidemiologic studies of GBS, a significant source of neonatal disease.
