Acid-fast rods,1.5-4 x 0.5 μm.
Colonies on egg medium appear in 7 days and are intermediate between smooth and
rough, and white to slightly yellowish in color but non-photochromogenic.
Temperature range for growth is 28-37 ºC. Grows in media supplemented with 5%
NaCl. Growth on MacConkey agar occurs at 28 ºC, but not at 37 ºC.

Isolated from bronchial aspirations from a child. Also isolated from skin and gills of fish (Ictalurus nebulosus & Carassius carassius).
Resistant to hydroxylamine (500 µg/ml) and doxycycline (16 mg/ml). Susceptible to amikacin (32 mg/ml).

Rarely a cause of pulmonary disease.

Positive results for arylsulfatase (3, 7 and 14 days), acid phosphatase, catalase inactivated at 68 ºC, iron uptake, nitrate reduction,
pyrazinamidase, tellurite reduction, and urea hydrolysis.
Can utilize as sole carbon source: fructose, glucose, succinate, pyruvate, propionate, mannitol and trehalose.
Negative results for niacin accumulation.
No utilization of benzoate, citrate, oxalate, xylose and sorbitol.
Variable results for Tween hydrolysis.
