Description

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

  • A commercial hybridisation assay (AccuProbe) to identify M. gordonae exists.[3]
  • Intraspecies variability in 16S rDNA sequences

Pathogenesis

  • 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

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