Gram-negative rods, 0.2-0.5 x 1.5-2.0 µm in size. Motile by polar flagella.
Non-sporogenous.
Non-sporogenous.
Colonies on BHI plates after 24 h of incubation at 30 ºC are white, round, convex,
smooth, with entire margins and approximately 1.0-4.0 mm in diameter. Growth
occurs in 0-4% (w/v) NaCl, at pH of pH 5-9 and temperatures of 4-37 ºC (but not at 41
and 44 ºC). Strictly aerobic.
