The carriage of group B streptococci in Turkish pregnant women and its transmission rate in newborns and serotype distribution.

The prevalence of group B streptococci (GBS) colonization was studied in 500 pregnant women and their newborn infants by collecting vaginal and rectal swabs from mothers, and umbilical and throat swabs from their infants. Forty-six isolates of GBS were obtained from mothers' specimens and eight from neonates. Maternal and infant colonization rates were found to be 9.
