Gram-negative rods, 0.5-1.0 x 1-3 µm. Motile by peritrichous flagella.
Colonies are generally mucoid, domed and can vary in color from white to cream.
Optimum growth temperature 26 - 30 ºC. No growth at 40 ºC. Facultatively anaerobic.

Positive results for catalase, H2S production (from cysteine), acid production from
fructose, D-galactose, D-glucose, D-mannose, salicin and sucrose.
Negative results for oxidase, nitrate reduction, indole production, arginine dihydrolase, lysine decarboxylase, ornithine decarboxylase,
starch hydrolysis, acid production from adonitol, dulcitol and lactose.
