Gram stains show characteristic bulges or knobs at the ends of some rods;
Gram-positive polymorphic coryneform rods. Nonspore-forming. Nonmotile. Mycolic
acids are present. Tuberculostearic acid is not present.
Colonies are buff or slightly yellowish and adherent to agar , with a sticky consistency,
opaque, shiny, and heaped. Haemolysis and CAMP test are negative. Growth in 6.5%
NaCl is variable. No growth in 10% NaCl.
It is infrequently encountered in human clinical material. Sensitive to penicillin and vancomycin.
Undetermined.

Fermentative metabolism.
Most biochemical characters were tested on API Coryne and API ZYM.

Positive results for catalase, alpha-glucosidase, hippurate hydrolysis, urease, acid production from: fructose, glucose, maltose &
sucrose.

Negative results for acid phosphatase, esculin hydrolysis, gelatin hydrolysis, lipophilism, nitrate reduction, oxidase, starch hydrolysis,
acid production (slowly) from: N-acetylglucosamine, amygdalin, galactose, glycogen, lactose, mannitol, raffinose, ribose, salicin,
trehalose & xylose.

Variable results for alkaline phosphatase.
