Group B Streptococcus (GBS) infection remains a significant cause of neonatal morbidity and mortality. Adoption of screening for maternal genital tract colonization and intrapartum antibiotic prophylaxis has significantly reduced early-onset neonatal GBS infections. For women with an allergy to penicillin, recommended agents for prophylaxis have been well-outlined, but compliance with.
