This Gram positive coccus is most frequently found in pairs and short chains of spherical or ovoid cells. It is catalase negative and exhibits facultatively anaerobic metabolism. Heat tolerant, surviving extended heating to 60 C. Isolated from the digestive systems and feces of humans and a variety of other animal, insects, plants, and non-sterile foodstuffs. Its routine presence in feces makes it a convenient indicator organism for testing the water sources for fecal contamination. It is an occasional pathogen in nosocomial infections (endocarditis, UTI, meningitis) often arising following dental procedures.
