Abstract Objective: To investigate the influence of group B streptococcal (GBS) caused reproductive tract infection of pregnant women on their premature rupture of membranes (PROM) and pregnancy outcomes. Methods: 80 pregnant women with PROM were randomly selected into the study group from April 2016 to April 2018, and other normal pregnant women were selected into the control group during the same time. The GBS samples came from vaginal and anal swabs of all women in the both groups were detected by real-time quantitative PCR. The prognosis of neonates born and pregnancy outcomes was observed. Results: The positive rate of GBS of women in the study group was 18.8%, which was significant higher than that (5.0%) of women in the control group (P<0.05). In the study group, the incidences of neonatal pneumonia, fetal distress and chorioamnionitis of women with GBS positive were 6.7%, 26.7%, and 20.0%, respectively, which were significant higher than those of women with GBS negative (P<0.05). The incidences of cesarean section, postpartum hemorrhage, premature delivery of women, and the jaundice, asphyxia, and GBS infection of newborn in the study group were 33.3%, 13.3%, 6.7%, 13.3%, 6.7%, and 6.7%, respectively, which were significant higher than those in the control group (P<0.05), but the incidence of body weight and Apgar score of newborn in the study group were significant lower than those of women in the control group (P<0.05). Conclusion: Group B streptococcus caused reproductive tract infection during pregnancy is closely related to premature rupture of membranes, which can lead to adverse pregnancy outcomes.
