孕妇B型链球菌感染率及药物敏感性分析

目的 调查研究妊娠妇女B群链球菌感染情况，以便加强预防措施，减低新生儿发病率。方法 对1056名怀孕35-37周的妇女进行阴道拭子培养，筛查B群链球菌，并对阳性标本进行药物敏感试验。结果 79份标本培养出B群链球菌，阳性率为7．5％。其中两例新生儿出生后患严重B群链球菌感染，一人死亡。药敏结果表明氨苄青霉素、先锋霉素敏感率为100％。结论 孕产妇B群链球菌感染非常普遍，是引起胎儿早产和死亡的重要原因之一。建议对孕妇进行阴道B群链球菌常规培养，如发现阳性，应立即治疗，保证胎儿健康。

Analysis of Group B Streptococcus infection and drug sensitivities in pregnant women

Objective To investigate the vaginal Group B Streptococcus infection among pregnant women, try to reduce the rate of neonatal infection. Method Routine vaginal secreta culture was applied among 1056 pregnant women at 35 to 37 week's gestation for Group B Streptococcus. Drug sensitivity tests were done on all positive specimens. Results 79 specimens were positive, with 7.5% of positive rate. The bacteria were 100% sensitive to Ampicillin and Cephalosporin. Conclusions Group B Streptococcus infection is very commonly seen among pregnant women. It is a significant cause of invasive disease in the newborn. In order to reduce the newborn infectious rate, it is very important to do screen test for Group B Streptococcus in pregnant women.
