Clinical Info

Streptococcus agalactiae (Group B) (GBS) has been recognized as the leading infectious cause of perinatal morbidity and mortality in the United States. Early onset neonatal disease results from transmission of GBS during labor and delivery from mother to infant. This can be characterized by septicemia, pneumonia, or meningitis and can result in death or permanent neurological problems.
Intrapartum ampicillin prophylaxis can prevent early onset neonatal GBS disease in women with positive prenatal cultures for GBS and certain prenatal risk factors. As a result, professional guidelines recommend that pregnant women be screened for GBS at 36 to 37 weeks of gestation.
