CLINICAL DIAGNOSTICS
Group B Streptococcus
Group B Streptococcus (GBS) infection is the infection caused by the bacterium Streptococcus agalactiae. Group B streptococcal infection can cause serious illness and sometimes death, especially in newborns, the elderly, and people with compromised immune systems. In general, GBS is a harmless commensal bacterium, being part of the human microbiota colonizing the gastrointestinal and genitourinary tracts of up to 30% of healthy human adults (asymptomatic carriers). Vaginal colonization rates range from 4 to 36%, with most studies reporting over 20%.
GBS is the main cause of bacterial infections in newborns, such as septicemia, pneumonia, and meningitis, which can lead to death or long-term after-effects. Infections in newborns are separated into two clinical types: early-onset disease (EOGBS) and late-onset disease (LOGBS). EOGBS manifests from 0 to 7 living days in the newborn, with most of the cases being apparent within 24 hours. LOGBS starts between 7 and 90 days after birth. EOGBS is acquired through exposure of the fetus or baby to GBS from the vagina either in utero or during birth.
