Gram-negative, small, coccoid rods, 1–2 μm long, occuring single, in pairs or in short
chains. Motility is variable.
On nutrient agar, colonies are flat or slightly convex with smooth margins and range
from white to light brown in colour. Can grow between 28 and 37 ºC and in 0-4.5%
NaCl. Does not grow on acetamide. Non-hemolytic. No growth on 10% lactose,
Tween 80 or oxidation–fermentation (OF) medium supplemented with glucose,
maltose, adonitol, fructose or xylose.
Isolated from blood.
Undetermined.
