Description[edit]
Gram-positive, nonmotile and pleomorphic acid-fast rods.
Colony characteristics
- Bright yellow pigmented, scotochromogenic and rough or smooth colonies on Löwenstein–Jensen medium.
Physiology
- Fast growth on Löwenstein–Jensen medium at 25 °C and 37 °C within 7 days. No growth at 45 °C.
- Resistant to isoniazid, rifampicin, and sodium aminosalicylate.
Differential characteristics
- Characterised by the possession of 6 species-specific antigens demonstrable in immunodiffusion tests.
Pathogenicity.
Pathogenesis[edit]
Not pathogenic, but evidence insufficient. Biosafety level 1.
Type strain[edit]
