Lancefield group D.
Lancefield group D.
Gram-positive cocci, non-motile, grouped in chains.
Colonies are non-pigmented, circular, 1 mm in diameter and alpha-haemolytic after
24 hours incubation on blood agar.
Growth temperature 37 °C, not at 10 or 45 °C. Facultatively anaerobic. Growth occurs
at pH 9.6 but not in broth containing 6.5% NaCl. Bile-aesculin test is negative.
