Colonies on nutrient agar are cream, circular/ slightly irregular and slightly convex.
Aerobic (no anaerobic growth). Growth occurs at 10-40 ºC, optimally at 32-35 ºC. Can
grow in pH 5.0–8.5 (optimum, pH 6.0).

Gram-negative rods, 0.5–0.8 x 1.1–1.8 μm. Motile by means of single polar flagella.
Spores are not formed.
