Description
Gram-positive, nonmotile and acid-fast rods (1-3 µm x 0.5-0.7 µm).
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.
- The type strain is resistant to D-cycloserine, streptomycin, isoniazid, rifampin, and thiacetazone
- The type strain is susceptible to kanamycin, capreomycin and high levels of isoniazid.
Differential characteristics
- Differentiation from all other mycobacterial species by its unusual mycolate pattern.
Pathogenesis
- Not associated with disease.
- Biosafety level 1
Type strain
First isolated from water samples, from soil and human sputum samples in Spain. Strain CR-21 = ATCC 51304 = CIP 103464 = DSM 44176 = JCM 12272.
