| | Epidemiology of disease caused by nontuberculous mycobacteria. |
 | | The clinically important nontuberculous mycobacteria include M. kansasii, M. genavense, M. marinum, M. simiae, M. scrofulaceum and M. szulgai, M. avium, M. haemophilum, M. intracellulare, M. malmoense, M. ulcerans, and M. xenopi, M. abscessus, M. chelonae, M. fortuitum, and (rarely) M. smegmatis. |
 | | All four clinical syndromes seem to be increasing in frequency, particularly in immunosuppressed hosts. |
 | | Nontuberculous mycobacteria are acquired from the environment, but specific reservoirs of these organisms leading to human disease have not been defined. |
