Streptococcus Group B is the most common cause of sepsis and meningitis and a leading cause of pneumonia in newborns. In adults who are not pregnant, Group B Streptococcus can cause infections of blood, skin, soft tissue, and lungs. Approximately 20-25% of pregnant women become infected. Infection is associated with complications of pregnancy and can be transmitted to the newborn. Results from bacterial antigen testing should be considered presumptive and culture with gram stain must also be performed.
