Gram-positive  coryneform cells, occurring as single cells or in V-shaped forms or
palisades. Non-motile. Non-spore-forming. Tuberculostearic acid is present. Mycolic
acids are not present.
Colonies on blood agar are non-pigmented, small, smooth and convex. Nonhemolytic
and CAMP-negative. Facultatively anaerobic. Grows in/at: 10% NaCl media. Can grow
at 42 ºC.
Isolated from human clinical samples. Habitat is unknown. Sensitive to cefuroxim, erythromycin, klindamycin, penicillin G and
vancomycin.
Isolated from human sputum of a patient with pulmonary disease, a brest abscess and from open-lung biopsy specimen.

Fermentative metabolism. Non-acid-fast.

Variable and weak acid production from maltose.

Positive results for esculin hydrolysis, lipophilism, pyrazinamidase, acid production from: glucose & sucrose.

Negative results for acid phosphatase, alkaline phosphatase, gelatin hydrolysis, nitrate reduction, urease, acid production from:
glycogen, lactose, mannitol, ribose & xylose.
