Gram-negative rods, 1.0 x 2.0 μm. Non-spore-forming. Non-motile.
More than one-half of E. vulneris strains produce a yellow pigment. Optimum growth
temperature 37 ºC. Grow readily on simple nutrient media like Nutrient agar or
nutrient broth. Facultatively anaerobic.

Isolated from the intestine of a cowbird in Michigan, USA. Other strains were isolated from human clinical specimens, primarily
wounds, the majority of which occurred on the arms or legs, but also blood, throat, sputum, vagina, urine, and stool, and other
warm-blooded animals.

Positive results for arginine dihydrolase (delayed), methyl red, nitrate reduction, ONPG, acid production from: L-arabinose, cellobiose,
glucose, D-mannitol, melibiose, raffinose, L-rhamnose, trehalose, and D-xylose.
Negative results for citrate utilization, Jordan's tartrate, corn oil, DNase, gelatinase, H2S production, indole production, phenylalanine
deaminase, oxidase, ornithine decarboxylase, urease, Voges-Prokauer test, acid production from: D-arabitol, adonitol, dulcitol,
erythritol, myo-inositol, and D-sorbitol.
Variable results for acetate and malonate utilization, lysine decarboxylase, growth in KCN, fermentation of alpha-methyl-D-glucoside,
lactose, sucrose and salicin.
