Mycobacterium gordonae is a Gram-positive, immobile rod-shaped bacterium. The pathogen belongs to the non‐tuberculous mycobacteria (NTM) from the strain of actinobacteria.
Mycobacterium gordonae causes diseases similar to tuberculosis. Nosocomial diseases are also described. Disease patterns include:
Keratitis (inflammation of the cornea)
Mycobacterium gordonae is widespread in the soil and in (tap) water. It can also often be detected on mucous membranes of healthy people.
Relevance of pathogen in transmission in endoscopy
Gastroenterology: Not relevant
Ear, nose, and throat: Not relevant
Relevance for endoscope surveillance
Low or moderate concern organism
Mycobacterium gordonae primarily occurs in tap water and can therefore infect humans.
The pathogen can also be spread and transmitted through water in healthcare facilities. The water used for final rinsing of endoscopes must therefore be microbiologically controlled.
Resistance to antibiotics
Mycobacterium gordonae shows strong antibiotic resistance, including to isoniazid.
