摘要:

目的 对妊娠末期孕妇B族链球菌(GBS)的检测方法进行评估。方法 对产检的300例妊娠末期孕妇的生殖道分泌物样本分别用肉汤增菌转种血平板法、GBS筛查培养基法及聚合酶链反应(PCR)进行GBS检测,对各方法进行评估。结果 肉汤增菌转种血平板法和GBS筛查培养基法的GBS阳性检出率分别为5.3%和7.0%,二者差异无统计学意义(P>0.05);PCR GBS阳性检出率为9.6%,与2种细菌培养法阳性检出率差异有统计学意义(P<0.05)。结论 PCR是妊娠末期孕妇常规检测GBS感染的首选方法,可用于孕妇临产前的快速检测。

Abstract:

Objective To evaluate the detection methods of group B Streptococcus(GBS) in late pregnancy. Methods A total of 300 cases of prenatal genital tract secretion samples in late pregnancy were detected for GBS by broth enrichment switched to blood plate method,screening for GBS cultivation medium method and polymerase chain reaction(PCR). Methodological evaluation was performed. Results The detection rates of GBS by broth enrichment switched to blood plate method and screening for GBS cultivation medium method were 5.3% and 7.0%,without statistical significance(P>0.05). The detection rate of GBS by PCR was 9.6%,and there was statistical significance with the other 2 methods(P<0.05). Conclusions PCR is a good choice for GBS detection in late pregnancy. It can be used in the rapid detection of GBS for pregnant women before delivery.
