Colonies on Mueller-Hinton agar or nutrient agar are slightly raised, yellowish green,
and glistening, have entire edges, and are about 1-1.5 mm in diameter after 17 h of
incubation at 37 ºC in a humid atmosphere. Moderate hemolysis of horse blood agar
and rabbit blood agar. Aerobic. Grows at 35-37 ºC; less growth at 30 ºC. Growth
enhanced by 5-8% CO2 at 30, 35, or 37 ºC. Slight or no growth at 22 and 42 ºC.

Vedros et al. 1983.
Gram-negative cocci 0.6-1.0 μm in diameter, occuring singly or grouped in pairs with
adjacent sides ﬂattened. Nonmotile. Endospores are not produced.
