Description edit
Gram-positive, nonmotile and acid-fast rods. Cells are typically rod-shaped, with some coccoid forms.
Colony characteristics Smooth, yellow scotochromogenic colonies appear after 4 weeks of culture.
- Slowly growing organism, colonies appear after 4 weeks of growth.
- Able to grow at 37 °C and 45 °C.
Differential characteristics
- The phylogenetic position of this species is within the cluster defined by M. xenopi and M. botniense.
- Key differentiating features are negative tests for arylsulfatase and pyrazinamidase and susceptibility to antimycobacterial drugs.
Pathogenesis edit
- Seems to be pathogenic in immunocompetent humans.
- Biosafety level unknown
Type strain edit
- The type strain was isolated from human lung by bronchoscopy.
Strain S369 = CCUG 51897 = DSM 44428
