Description
Microscopy- Gram-positive, nonmotile and acid-fast rods (1-3 µm x 0.5-0.7 µm), mostly strong acid-fast.
Colony characteristics
- Colonies are eugonic, rough and nonpigmented.
Physiology
- Colonies occur within 5 days at 30°C (optimum temperature, no growth at 45°C) on Löwenstein-Jensen medium and on Middlebrook 7H10 agar.
- No growth on MacConkey agar without crystal violet.
- The type strain is resistant to D-cycloserine, streptomycin, isoniazid (0.1 and 1 mg/l), rifampin, and thiacetazone and is susceptible to isoniazid (10 mg/l), kanamycin, and capreomycin.
Type strain
- First isolated from water samples, from soil and human sputum samples, Spain.
- Strain AR30097 = ATCC BAA-1242 = DSM 44942.
