Which condition is most closely associated with the presence of Group B Strep?

Group B Streptococcus (GBS), specifically Streptococcus agalactiae, is most commonly associated with neonatal infections. This bacterium can colonize the genital tract of pregnant individuals and can be transmitted to the newborn during delivery. If the newborn becomes infected with GBS, it can lead to serious conditions such as sepsis, pneumonia, and meningitis shortly after birth.

Screening for GBS in pregnant individuals is a standard part of prenatal care, and appropriate antibiotic prophylaxis is administered during labor to reduce the risk of transmission to the infant, underscoring the importance of recognizing the association between GBS and neonatal infections.

While GBS can also be implicated in other infections, such as urinary tract infections in adults and occasionally respiratory infections, these associations are less prominent than its role in neonatal morbidity and mortality.
