Background
- Gram-positive anaerobic coccus
- Commensal member of the gut microbiota, occasionally urogenital tract and skin
Clinical Manifestations
- Chronic apical periodontitis
- Bacteremia[1]
- Can be from discitis (30%), oropharyngeal infection (25%), intraabdominal abscess (15%), GI tract infection (10%), endocarditis (10%), and septic pulmonary emboli (10%)
