Acid-alcohol-fast, small rods. Does not produce capsules or spores. Non-motile.
Colonies on Lowenstein-Jensen medium after 2 weeks incubation are small (< 1
mm), round, smooth, raised with round or lobate regular margins. Scotochromogenic.
Temperature range for growth is 25-37 ºC; does not grow at 42 ºC or above. Does not
grow on MacConkey agar (without crystal violet) or on 5% (w/v) NaCl agar.

Isolated from a cervical lymph node of a 3-year-old child with bilateral lymphadenitis. Susceptible to ciprofloxacin, clofazimine,
hydroxylamine (500 μg/ml), ethambutol (2 μg/ml), rifampin (32 μg/ml), and streptomycin (8 μg/ml). Resistant to isoniazid (1 μg/ml),
and thiophene-2-carboxylic acid hydrazide.

Has been identified as the cause of cervical lymphadenitis in a child.

Positive results for heat-stable catalase (68 ºC), Tween 80 hydrolysis, and urease.
Negative results for arylsulfatase (3 days), semiquantitative catalase test, beta-glucosidase, niacin accumulation, nitrate reduction, and
tellurite reduction (9 days).
