Gram-negative, spiral or S-shaped cells, 2.1-2.5 µm. Fresh cells are motile and have
long bipolar single flagella.

After 48 h of growth on Karmali or Columbia agar with 5% defibrinated sheep blood in
a microaerophilic atmosphere at 37 ºC. The colonies are wet, flat, gray, circular, and
smooth, with sizes between 1.0 and 1.3 mm after 2 days of growth, but they may vary
in size and morphology after a long incubation. No hemolysis on blood agar.
