To determine the vaginal-rectal colonization rate with group A streptococci in late pregnancy.
All patients delivering at a northern New England hospital over a 38 month period had 35-37 week vaginal-rectal swabs cultured for group A and group B streptococci, using selective media and slide agglutination.
Six thousand nine hundred forty-four screening cultures were obtained. Among these 1,393 were positive for group B streptococci and 2 for group A streptococci, yielding colonization rates of 20.1% and 0.03%, respectively.
Vaginal-rectal colonization with group A streptococci is rare, arguing against the need for establishing group A streptococcal screening programs in pregnancy. An approach for managing this uncommon finding is presented.
确定妊娠晚期A组链球菌的阴道-直肠定植率。
在新英格兰北部一家医院分娩的所有患者，在38个月期间，于孕35 - 37周采集阴道-直肠拭子，使用选择性培养基和玻片凝集法培养A组和B组链球菌。
共获得6944份筛查培养物。其中1393份B组链球菌阳性，2份A组链球菌阳性，定植率分别为20.1%和0.03%。
A组链球菌的阴道-直肠定植罕见，因此反对在孕期开展A组链球菌筛查项目。本文提出了针对这一罕见发现的处理方法。
