Preterm labor and bacterial vaginosis-associated bacteria among urban women

Abstract
Aims: Bacterial vaginosis (BV) affects millions of women, is extremely prevalent and is frequently chronic. We recognize numerous microbiologic variations among women with BV and this variability may explain the limited effectiveness of metronidazole in curing BV and/or reducing the risk of spontaneous preterm birth (SPTB) among BV-positive pregnant women. We assessed the independent role of seven common BV-associated bacteria on the risk of spontaneous preterm birth (SPTB) among urban pregnant women.
