The vagina or rectum is colonized with group B streptococcus (GBS) in 10 to 40 percent of women.7,8 Early-onset GBS disease is the most common cause of serious infection during the newborn period; it occurs in one in 1,000 births.7 Universal screening consisting of a lower vaginal and rectal swab at 35 to 37 weeks' gestation and appropriate intrapartum chemoprophylaxis in GBS-positive women reduces the incidence of early-onset infections in neonates.8 unless the bacteria are cultured from urine, there is no need for GBS treatment until the onset of labor. I if GBS status is unknown at the start of labor, many physicians choose to treat prophylactically; however, this strategy is not recommended by the Centers for Disease Control and Prevention (CDC).8 E exceptions to these recommendations are noted in online Figure A, which is an algorithm for the prophylaxis of GBS during labor.8

In women who test positive for GBS or have other indications for prophylaxis, antibiotic therapy should be instituted at the onset of labor. Currently, preferred treatment consists of at least one dose of intravenous penicillin (5 million units) given a minimum of four hours before delivery. If labor continues beyond four hours, subsequent doses (2.5 million units) should be given every four hours until delivery. A although there is concern that GBS strains are becoming resistant to routinely administered antibiotics, no recent statistically significant increase in resistance has been noted.9 ampicillin remains an alternative to penicillin; options for penicillin-allergic patients include cefazolin (Kefzol; brand not available in the U united S states), clindamycin (Cleocin), erythromycin, or vancomycin (Vancocin).8 T the CDC recommends treatment based on GBS sensitivity patterns in women who are at high risk of anaphylaxis with penicillin.8
