Acid-alcohol-fast rods. Gram-positive.
Colonies are domed, smooth, dark orange/yellow and grow on 5% sheep blood agar,
Middlebrook 7H10 agar and Lowenstein-Jensen agar after 5 days at 24-42 ºC,
optimum at 37 ºC (weak growth at 42 ºC). Can grow on MacConkey agar without
crystal violet, but not on 5% NaCl media.

Undetermined.
Isolated from sputum and blood culture specimens.
Susceptible to sulfamethoxazole+trimethoprim, linezolid, clarithromycin, ciprofloxacin, imipenem, moxifloxacin, amikacin, doxycycline
and minocycline and show intermediate susceptibility to cefoxitin.

Positive results for iron uptake, nitrate reductase, Tween 80 hydrolysis and urease.
Can utilize as sole carbon source: D-glucose, D-mannitol, D-sorbitol, and L-rhamnose.
Negative results for arylsulfatase (3 days), arginine dihydrolase, and ornithine decarboxylase.
No utilization of citrate and inositol.
