Evaluation of probiotic oral supplementation effects on group B streptococcus rectovaginal colonization in pregnant women: a randomized double-blind placebo-controlled trial

Recently, lactobacilli-containing probiotics have been studied for use in a variety of conditions, including urogenital infections. We sought to determine if antenatal probiotic supplementation during second and third trimesters reduces maternal GBS rectovaginal colonization in pregnant women at 35-37 weeks’ gestational age.
