Who is the study for?
This trial is for healthy adult pregnant women at 28±2 weeks gestation, who speak and read English, attend regular prenatal care, and have no fetal or medical complications like birth defects or diabetes. It's not for those taking over-the-counter probiotics (except yogurt), with a history of severe reactions to β-lactam antibiotics, or any obstetric complications.Check my eligibility
What is being tested?
The study tests if the oral probiotic Florajen3 can reduce Group B Streptococcus colonization in pregnant women. Participants are randomly assigned to receive either Florajen3 or a placebo without knowing which one they get. The study measures GBS levels at around 36 weeks of pregnancy and effects on maternal and neonatal GBS during labor.See study design
What are the potential side effects?
While specific side effects aren't listed for this trial, common side effects from probiotics may include digestive discomfort such as gas or bloating. However, these tend to be mild.
