Gram-positive, ovoid cells, occurring in pairs, groups, or chains. Non-spore- forming.
Non-motile.
Colonies on 5% blood agar are non-pigmented, alpha- or gamma-hemolytic.
Facultatively anaerobic. No growth at 10 ºC; some strains may grow at 45 ºC. Grows
in 6.5% NaCl. No growth on bile-esculin agar.
Isolated from human clinical specimens. Habitat is not known. Vancomycin-sensitive.
Undetermined. Isolated from blood, wound and ear abscess.
