Gram-negative, nonsporing rods, 1.0 x 1.0-3.0 μm, motile by peritrichous flagella.
Colonies on nutrient agar are smooth, translucent, and more or less convex with
entire margins, nonpigmented. Facultatively anaerobic, growth temperature 30-37 ºC.
Grow on media: Nutrient agar or nutrient broth; Trypticase Soy Agar ± 5% sheep blood;
Luria-Bertani. Can grow on KCN.
