This Gram positive coccus is most frequently found in pairs and short to long chains of spherical or ovoid cells. Cells are catalase negative and exhibit facultatively anaerobic metabolism. Heat tolerant to 60 C for extended periods. Isolated from the digestive systems (most likely the rumens) of a variety of domesticated animals and from a variety of milk products. It has been implicated as a cause of endocarditis, meningitis, and neonatal septicemia. There is evidence linking some strains to colorectal cancer.
