Gram-positive coryneform rods. Nonmotile. Spores are not produced. Mycolic acids
are not present.
Colonies are opaque, convex, smooth-creamy, whitish-grey, with butyrous
consistency. CAMP test is negative. Aerobic. Nonfastidious. Grows optimally at 30-37
ºC. No growth at 10 ºC.
Isolated from bumble-foot-like manifestations of poultry.
Unclear. Non-pathogenic for experimentally injected animals. May be secondary invaders.

Oxidative metabolism. Not acid fast.
Some biochemical characters where tested on API 50CH and API ZYM kits.

Positive results for acid phosphatase, alkaline phosphatase, casein hydrolysis, catalase, cystine arylamidase, DNA hydrolysis,
esterase C4, gelatin hydrolysis, leucine arylamidase, nitrate reduction, oxidase, phosphoamidase, tyrosine decomposition & xanthine
hydrolysis.

Negative results for chymotrypsin, esculin hydrolysis, alpha-fucosidase, alpha- and beta-galactosidase, alpha- and
beta-glucosidase, beta-glucuronidase, N-acetyl-beta-glucosaminidase, lipase, alpha-mannosidase, starch hydrolysis, trypsin,
urease, valine arylamidase, acid production from: glucose, maltose, sucrose, mannitol & xylose.

Can utilize: L-arabinose, D-arabitol, fructose, galactose, D-glucose, glycerol, mannitol & mannose.
Cannot utilize D-arabinose & gluconate.
