Clinical significance of group B streptococcus testing in late pregnancy
Purpose:
This study aimed to detect the maternal group B streptococcus (GBS) by real-time PCR method, aiming to understand its germ-carrying situations and clinical significance.
Materials And Methods:
The secretions of one-third inferior segment of maternal vagina of 1,540 pregnant and postnatal women were collected for GBS detection by real-time PCR method, and the impacts of positive results on the fetus were observed.
Results:
The detection rate of GBS was 5.6% (86/1540); the premature birth rate of GBS-positive pregnant women was 29.1% (25/86), the miscarriage rate was 19.8% (17/86), the premature rupture rate was 26.7% (23/86), and the fetal distress rate was 24.4% (21/86).
Conclusions:
The GBS germ-carriers showed increased rates of premature birth, miscarriage, premature rupture, and fetal distress, thus forming adverse effects towards the maternal and infant outcomes.
