Gram-negative rods, 0.4-0.6 x 0.8-0.9 μm. Non-motile. Non-spore-forming.
Colonies are convex, opaque, circular, smooth, milky white and about 1.0 mm in
diameter after 24h incubation on BHI-sheep blood agar. Growth also occurs on
Columbia blood agar, MacConkey agar and BHI agar. Optimal growth occurs at 37 ºC
(range, 25-42 ºC), pH 7.5 (range, 5.0–9.0) and 2.0% NaCl
(range, 0-4.5%). Facultatively anaerobic.
