Abstract

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．

Key words: Polymerase chain reaction, Bacterial cultivation, Group B Streptococcus, Late pregnancy
