Overview
Group B streptococcal (GBS) infection can be classified into three main categories depending on the type of affected subjects. GBS infection can occur in pregnant women, neonates, or non-pregnant adults mainly the elderly.[1] Neonatal GBS infection can be further classified into early-onset or late-onset depending on the timing of the onset of the symptoms. Infections in newborns occurring within the first week of life are designated as early-onset disease, whereas late-onset infections occur in infants aged >1 week, with most infections evident during the first 3 months of life. [2]
Classification
Infection in Pregnant Women
GBS infection in pregnant women can lead to any of the following:
- No symptoms (asymptomatic carrier)
- Urinary tract infection
- Chorioamnionitis
- Endometritis
- Premature rupture of membrane
Infection in Neonates
GBS infection in neonates can be classified as:[2]
- Early onset infection (within 24-48 hours, up to one week after delivery), which can lead to any of the following:
- Late onset infection (after the first week, up to 3 months of life), which can lead to any of the following:
- Bacteremia without a focus of infection
- Sepsis
- Meningitis
- Pneumonia
- Focal infections (less commonly) such as adenitis, cellulitis, and arthritis[3]
Infection in Men and Non-Pregnant Women
GBS infection in non pregnant adults occurs mainly in elderly and subjects with underlying disease, such as diabetes.[1] GBS infection in elderly can manifest as any of the following:[4]
- Pneumonia
- Skin and soft tissue infection
- Osteomyelitis
- Septic arthritis
- Urosepsis
- Peritonitis
- Meningitis
- Endocarditis
- IV catheter infection
