This Gram positive coccus is most frequently found in pairs and long chains of spherical or ovoid cells. Cells are catalase negative and exhibit facultatively anaerobic metabolism. It is encountered most often in secretions and on mucous membranes of humans and other mammals (camels, sea mammals, pets) and reptiles. It is considered part of the normal digestive flora of humans. If it finds its way to the vagina, it can be a danger to newborns and is a leading cause of neonatal septicemia (so called Group B Strep, or GBS, infections). It is also a threat for nosocomial infections of the elderly and immunocompromised.
