Information About Group B Strep

*Although some important changes have been instituted, many recommendations remain the same:

Penicillin remains the first line agent for intrapartum antibiotic prophylaxis, with ampicillin an acceptable alternative
Women whose culture results are unknown at the time of delivery should be managed according to the risk-based approach; the obstetric risk factors remain unchanged (i.e., <37 weeks’ gestation, duration of membrane rupture >18 hours, or temperature >100.4 F (>38.0 C))
Women with negative vaginal and rectal group B strep screening cultures within 5 weeks of delivery do not require intrapartum antimicrobial prophylaxis for group B strep, even if they develop obstetric risk factors (i.e., <37 weeks’ gestation, duration of membrane rupture >18 hours, or temperature >100.4 F (>38.0 C))
Women with group B strep bacteriuria in any concentration during their current pregnancy or who previously gave birth to an infant with early-onset group B strep disease should receive intrapartum antimicrobial prophylaxis
