Acid-alcohol-fast, moderately long to long rods. Gram-stain-positive.
Colonies on Lowenstein–Jensen medium and Middlebrook agar are smooth to rough
and white to buff after incubation for 7 or more days at 37 ºC. Grows at 22-37 ºC. Weak
growth at 42 ºC and no growth at 45 ºC. Growth time varies between 12 and 28 days.
No growth on 5% (w/v) NaCl.

Isolated from soil, water and bovine nasal swabs. Environmental contaminant of clinical specimens. One isolate from roach skin
(Rutilus rutilus).
Susceptible to ethambutol (2 µg/ml). Resistant to TCH (1 µg/ml), hydroxylamine (500 µg/ml), isoniazid (1 µg/ml), rifampin (25 μg/ml),
and streptomycin (2 µg/ml).
(Rutilus rutilus).
Susceptible to ethambutol (2 µg/ml). Resistant to TCH (1 µg/ml), hydroxylamine (500 µg/ml), isoniazid (1 µg/ml), rifampin (25 μg/ml),
and streptomycin (2 µg/ml).
Isolated from mice injected with soil. Bacilli persist in tissues of mice without evidence of pathogenicity.
