Carvalho et al. 2006. Lancefield group D.
Gram-positive cocci, grouped in short chains, in pairs or single cells. Non-motile.
Colonies on blood agar, incubated at 37 ºC, are nonpigmented, alpha-hemolytic, and
small, up to 0.5 mm in diameter.
Growth occurs at 45 ºC and in broth containing 6.5% NaCl.
Isolated from human stool samples and fermented cereal grains. Susceptible to vancomycin.
Possible lactic acid bacteria.
