Description

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.

Physiology

  • 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

  • Seems to be pathogenic in immunocompetent humans.
  • Biosafety level unknown

    • Type strain

  • The type strain was isolated from human lung by bronchoscopy.

    • Strain S369 = CCUG 51897 = DSM 44428
