Background
Microbiology
- Gram-positive coccus in chains
- Identified with the help of a CAMP test, where β-hemolysis is induced by the presence of Staphylococcus aureus
Epidemiology
- Previously the most common cause of neonatal sepsis, until screening and prophylaxis during pregnancy and deliverybecame routine
Clinical Manifestations
Neonatal
- May be either early-onset (< 7 days old) or late-onset (7 to 90 days old)
- Presents with bacteremia, sepsis, pneumonia, and meningitis
Older Children and Adults
- Similar spectrum of illness to Streptococcus pyogenes
