Among urban, primarily African American pregnant women, 74% were identified with Nugent score bacterial vaginosis (BV). All BV-associated bacteria were more prevalent among women with Nugent score BV. Bacterial vaginosis–associated bacteria 3 (BVAB3) had the highest positive predictive value, whereas Gardnerella vaginalis and Atopobium spp. had the highest sensitivity. Atopobium spp. levels had the most significant area under the curve.

High levels of Atopobium spp. were related to Nugent score bacterial vaginosis among urban, pregnant women. Levels of Atopobium spp. early in pregnancy were highly sensitive and specific for bacterial vaginosis.
