Description

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

  • Commonly found in tap water and soil. Casual resident in human sputum and gastric lavage specimens.

    • Colony characteristics

  • Smooth, with yellow or orange scotochromogenic colonies. Even though they are scotochromogenic pigment is intensified by growing in continuous light.

    • 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.

    • Differential characteristics

  • A commercial hybridisation assay (AccuProbe) to identify M. gordonae exists.
  • 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.
  • Biosafety level 2

    • Type strain

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