Abstract
A study was conducted in 507 pregnant women of different parities, trimesters of pregnancy and age groups for finding out the colonisation rate of group B streptococci either in throat or vagina or from both sites. Incidence of carriage rate in throat was 4.73%, in vagina 9.66% and in both sites 12.03%. Age, parity, gestational period of women were not found to have any significant influence on the colonisation rate at different sites. Isolation rate of the organism was greatly enhanced using two selective media for isolation compared to using single selective medium or combination of non-selective media and a single selective medium.
