GBS
Also written as: GBS — Group B Streptococcus
Group B Streptococcus bacteria that can cause serious infections in newborns during delivery.
Full Definition
Group B Streptococcus (Streptococcus agalactiae), a type of bacteria commonly found in the intestinal tract and lower genital tract of healthy adults. While usually harmless to adults, GBS can cause serious infections in newborns who are exposed during delivery, including sepsis, pneumonia, and meningitis. Pregnant women are routinely screened for GBS colonization between 35-37 weeks of pregnancy through vaginal and rectal cultures. Women who test positive receive intrapartum antibiotic prophylaxis during labor to reduce the risk of transmission to the baby.
Usage
Usage note: Always use 'GBS' rather than 'Group B Strep' in formal medical documentation.
