Acid-fast, rods, delicate, slender, and often slightly curved (1.2-3.0 μm in length).
Colonies are smooth, often umbonate, non-chromogenic, and off-white to grayish
in color. Growth occurs on Middlebrook 7H11 agar after incubation for 2-3 weeks.
Temperature range for growth is 25-45 ºC.

Isolated from from nine patients, some of whom had cavitary mycobacteriosis of the lungs. Susceptible to ethambutol (2 μg/ml),
streptomycin (8 μg/ml), ethionamide, and capreomycin. Resistant to isoniazid (1 μg/ml), rifampin (32 μg/ml), and cycloserine.

Considered as a potential human pathogen.

Positive results for arylsulfatase (14 days), nicotinamidase (weak reaction) and
pyrazinamidase (weak reaction).
Negative results for arylsulfatase (3 days), Heat-stable catalase (68 ºC), semiquantitative catalase test, niacin accumulation, nitrate
reduction, Tween 80 hydrolysis, and urease.
