Acid-fast rods. Gram-positive.
Colonies are nonpigmented and appear on 5% sheep blood agar, Middlebrook
7H10 agar, and egg-based Lowenstein-Jensen slants in 2 to 5 days at temperatures
between 25 and 37 ºC, optimally at 30 ºC. No growth occurs at 42 ºC. Grows in the
presence of 5% (w/v) NaCl.

Isolated from wound liquid outflow, bone tissue biopsy, excised skin tissue, subcutaneous abscess and sputum.
Susceptible in vitro to imipenem, minocycline, doxycycline, clarithromycin, erythromycin, azithromycin, amikacin, ciprofloxacin,
ofloxacin, sparfloxacin, and amoxicillin clavulanate. Resistant to penicillin, rifampin, amoxicillin, and vancomycin.

Associated with posttraumatic osteitis. May cause pulmonary and skin infections, and prostetic infections.

Positive results for arylsulfatase (3 days), alkaline phosphatase, catalase, alpha-glucosidase, nitrate reduction, penicillinase,
pyrazimidase, iron uptake, and acetoin production.
Can utilize inositol as sole carbon source.
Negative results for arginine dihydrolase, gelatinase, beta-glucuronidase, beta-galactosidase, indole production, lysine
decarboxylase, niacin accumulation, ornithine decarboxylase, pyrrolidonyl arylamidase, and urease.
No utilization as sole carbon source of D-glucose, D-mannitol, sorbitol, rhamnose, D-saccharose, D-melobiose, amygdalin,
