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.
