Objective: To discuss the relationship of group B streptocceus and premature rapture of membranes by polymerase chain reaction （ PCR). Method: 316 cases of pregnant women to take reproductive tract bacterial culture for group B streptococcus screening results were summarized as the control group,316 eases of pregnant women on the same genital group B streptococcal screening and summarizing results by PCR were summarized as the study group; compared the accuracy of screening results in two groups. Then in accordance with the results, 316 cases of pregnant women were divided into screening positive and negative groups, then analyzed the relationship of group B streptococcus and premature rupture of membranes. Re.suit: Reproductive tract in control group B streptococcus positive test accuracy was 76.53％, the study group was 98.98％; The incidence of premature rupture of membranes in positive group was 29.59％ ,the negative group was 11.93％. Conclusion: PCR detection rate was significantly higher than that of bacterial culture,early detection of group B streptococcus infection of reproductive tract can effectively reduce or prevent the occurrence of premature rupture of membranes.%目的:探讨应用聚合酶链反应技术检测B群链球菌与胎膜早破之间的关系.方法:将316例孕妇采取细菌培养法进行生殖道B群链球菌筛查的结果汇总为对照组,再采取聚合酶链反应技术对同样316例孕妇实施生殖道B群链球菌筛查并将结果汇总为研究组;对比两组筛查结果的准确性.而后按照筛查结果将316例孕妇分为阳性组与阴性组,通过对比分析B群链球菌与发生胎膜早破的关系.结果:对照组生殖道B群链球菌阳性检测准确率为76.53%,研究组准确率为98.98%;阳性组胎膜早破发生率为29.59%,阴性组发生率为11.93%.结论:聚合酶链反应技术的检出率明显高于细菌培养法,尽早检出生殖道B群链球菌感染可有效降低或预防胎膜早破的发生.
