Nontuberculous mycobacteria (NTM), also known as environmental mycobacteria, atypical mycobacteria and mycobacteria other than tuberculosis (MOTT), are mycobacteria which do not cause tuberculosis or leprosy (also known as Hansen's disease). One of the most widely used broth systems is the nonradiometric mycobacteria growth indicator tube (MGIT) (Becton Dickinson, Sparks, MD), which contains a modified Middlebrook 7H9 broth in conjunction with a fluorescence quenchingbased oxygen sensor to detect mycobacterial growth. M. chelonae, M. fortuitum, and M. abscessus comprise the three important rapidly growing species, all of which can cause pulmonary disease. 1. Half of these individuals subsequently proved to be culture positive for MAC. There are difficulties with these criteria; for example, patients with radiographically progressive MAC infection may be asymptomatic, and conversely, symptoms may be a reflection of the underlying pulmonary disease that predisposes an individual to colonization/infection by NTMB rather than being caused by the NTMB itself.
