Pulmonary mycobacterium fortuitum infection

Last revised by Daniel J Bell on 2 Apr 2023

Pulmonary mycobacterium fortuitum infection is considered a rare form of pulmonary non-tuberculous mycobacterial infection occurring from the organism Mycobacterium fortuitum.

Presence of Mycobacterium fortuitum in respiratory tracts usually indicates mere colonization or transient infection although lung changes as a direct involvement can occur in certain individuals. Most Mycobacterium fortuitum infections are thought to arise from direct inoculation through skin lesions 2. Some increased predisposition in those with swallowing disorders has been suggested 3. Patients with underlying lung disease such as prior tuberculosis or bronchiectasis may also be at greater risk 4.
