[edit] 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 (1mg/l), isoniazid (10mg/l) and sodium chloride (5%).

Differential characteristics

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

[edit] Pathogenesis

• Rarely if ever implicated in disease processes unless patients are immunocompromised.
• Biosafety level 1
