Association of antibiotic treatment for second-trimester GBS with reduced miscarriage risk: Probiotic intervention shows no benefit

GBS colonization rate was 14.7% in the second trimester of pregnancy. GBS infection can increase the risk of threatened miscarriage and miscarriage as well as the risk of adverse pregnancy outcomes. Early intervention with antibiotics can increase the negative conversion rate of GBS, reduce the incidence of threatened miscarriage and miscarriage, and ameliorate the adverse outcome of pregnancy. The effect of probiotic intervention on the negative conversion of GBS was insignificant.
