Group B Streptococcus (GBS) are bacteria commonly found in the intestines and lower genital tract. Usually harmless in adults, they can cause serious infections in newborns. Pregnant women are often screened for GBS, as an infection during childbirth can lead to life-threatening complications like pneumonia, meningitis, and sepsis in babies. Treatment for GBS typically involves antibiotics during delivery to reduce the risk of transmission to the infant. This approach is crucial for ensuring the health and safety of both mother and child.
