Acid-alcohol-fast, short rods. No spore or capsule production.
Colonies are 1-2 mm in diameter, smooth, nonchromogenic, and raised with round
or lobate regular margins on Middlebrook 7H9 agar and on 2% Ogawa medium after
incubation for 7-14 days. Neither spores nor capsules are observed. Temperature
range for growth is 25-42 ºC. Growth occurs in culture medium with hydroxylamine.
Does not grow on media supplemented with 5% (w/v) NaCl or 0.2% picrate.

Isolated from sputum. One isoalte from Stone Moroko intestine (Pseudorasbora parva). Susceptible to amikacin, clarithromycin,
ethambutol, ethionamid, levofloxacin, rifampicin, and streptomycin. Resistant to isoniazid.
