Description

edit
 
Slant tubes of Löwenstein-Jensen medium. From left to right:
- Negative control
- M. tuberculosis: Dry-appearing colonies
- Mycobacterium avium complex: Wet-appearing colonies
- M. gordonae: Yellowish colonies

Gram-positive, nonmotile and moderate to long acid-fast rods.

Colony characteristics

Physiology

  • Growth on Löwenstein-Jensen medium and Middlebrook 7H10 agar within 7 or more days at 37 °C (optimal 25 °C).
  • Does not grow in the presence of ethambutol (1 mg/L), isoniazid (10 mg/L) and sodium chloride (5%).
  • Some strains can grow using carbon monoxide as a carbon and energy source.[2]

Differential characteristics

Pathogenesis

edit
  • Rarely if ever implicated in disease processes even if patients are immunocompromised. Widely distributed in environment and usually a contaminant in laboratory specimens.[4]
  • Biosafety level 2

Type strain

edit

Strain ATCC 14470 = CCUG 21801 = CCUG 21811 = CIP 104529 = DSM 44160 = JCM 6382 = NCTC 10267.
