Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The investigators wish to determine if oral probiotic supplementation during the second half of pregnancy decreases maternal GBS recto-vaginal colonization at 35-37 weeks' gestational age, thereby decreasing need for maternal antibiotic administration at time of labor. The importance of this study is that it may offer a safer alternative to antibiotic treatment of group B Streptococcus (GBS) colonized pregnant women.
