Acid-alcohol-fast rods. Gram-positive.
Colonies are smooth to mucoid,off-white- to cream-coloured on Middlebrook
7H10 and trypticase soy agar. Produces visible growth in 2-4 days. Yellow to orange
pigment is produced by most isolates after 10-14 days incubation and growth occurs
at 30, 35 and 45 ºC. Grows on MacConkey agar without crystal violet and in the
presence of 5% NaCl.

Undetermined. May be involved in granulomatous pneumonia, post-traumatic wound infections, especially those following open
fractures and with associated osteomyelitis.
fractures and with associated osteomyelitis.
Isolated from sputum, bronchial wash, infected wounds, osteomyelitis, intravenous catheter sepsis, cardiac bypass infection.
Susceptible to amikacin, ethambutol (5 µg/ml), sulfamethoxazole, intermediately susceptible to ciprofloxacin, doxycycline and
tobramycin, variably susceptible to cefmetazole, cefoxitin and clarithromycin. Resistant to isoniazid (10 µg/ml) and rifampin (25 µg/ml).

Positive results for semiquantitative catalase test (45 mm foam), iron uptake, and nitrate reductase.
Can utilize as sole carbon source L-arabinose, D-glucitol (D-sorbitol), imyo-inositol, D-mannitol, L-rhamnose and D-xylose.
Negative results for arylsulfatase (3 days) and heat-stable catalase (68 ºC).
Few strains (11-33%) can utilize citrate, D-galactose or D-trehalose.
