Mycobacterium gordonae
Mycobacterium gordonae is a species of Mycobacterium named for Ruth E. Gordon.[1] It is a species of the phylum actinobacteria (Gram-positive bacteria with high guanine and cytosine content, one of the dominant phyla of all bacteria), belonging to the genus Mycobacterium.

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.[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.
gollark: What an interesting bug. I wonder why they did that.
gollark: Two TJ09s or winter magis?
gollark: TJ09...exists.
gollark: That's so TJ09.
gollark: Gold trophy is great. I can finally keep ridiculous amounts of hatchlings.
