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.
对507名不同胎次、孕期阶段和年龄组的孕妇进行了一项研究，以确定B族链球菌在咽喉或阴道或两个部位的定植率。咽喉部携带率为4.73%，阴道为9.66%，两个部位均为12.03%。未发现女性的年龄、胎次、妊娠期对不同部位的定植率有任何显著影响。与使用单一选择性培养基或非选择性培养基与单一选择性培养基组合相比，使用两种选择性培养基进行分离时，该菌的分离率大大提高。
