Gram-positive cocci, 0.3-0.7 μm in diameter, nonsporulated, nonmotile, grouped in
pairs or short chains.
Colonies on sheep-blood agar are circular, white to greyish, shiny, convex,
non-hemolytic and 1-2 mm in diameter after 48 h at 37 ºC in CO
2 - enriched
atmosphere. Growth also occurs in aerobic, microaerophilic and anaerobic
atmospheres. Optimum growth temperature is 37 ºC but growth is observed at 25-37
ºC. Growth occurs in the presence of 2% NaCl.
Isolated from human blood sample. Resistant to optochine.
