Group B Streptococcus Response After Probiotic Exposure

Plain-language summary
This is an open-label randomized control trial and feasibility study designed to determine the feasibility of a larger RCT in our setting that would examine prenatal probiotic use in Group B Strep (GBS) positive pregnant women at term. Investigators hope to address the question of whether prenatal oral probiotic use, taken by healthy low risk GBS positive women from approximately 37 weeks gestation until the time of birth, will reduce the number of women who test positive for GBS at the time of admission to Labor and Delivery (L\&D).
