epidemiology of infection by nontuberculous mycobacteria. mycobacterium avium, mycobacterium intracellulare, and mycobacterium scrofulaceum in acid, brown-water swamps of the southeastern united states and their association with environmental variables.mycobacterium avium, mycobacterium intracellulare, and mycobacterium scrofulaceum (mais) organisms were isolated and identified from waters, soils, aerosols, and droplets ejected from water collected from four geographically separate aquatic environments (okefenokee swamp, ga; dismal swamp, va; claytor lake, va; and cranberry glades, wv) during several seasons. recovery of mais was significantly higher from waters, soils, and aerosols collected from the two acid, brown-water swamps located in th ...19921736730
