(which do not cause tuberculosis) can be initiated when an individual comes into contact with the pathogen either through inhalation, or via cuts, abrasions, and wounds on skin, Signs and symptoms of Atypical Mycobacterial Infections vary, depending on the type of species causing the infection. Atypical mycobacterial infections are infections caused by a species of mycobacterium other than Mycobacterium tuberculosis, the causative bacteria of pulmonary TB and extrapulmonary TB including cutaneous TB; and Mycobacterium leprae, the cause of leprosy. Nontuberculous mycobacterial (NTM) lung infections are caused by NTM, most commonly M. avium complex (MAC). More than 120 species of mycobacteria have been identified that can cause disease in humans. These may include cough, shortness of breath, skin lesions, and swollen lymph nodes, The diagnosis is made through culture of body fluids and tissues, including of blood, sputum, and skin. have suggested that atypical mycobacterial disease in CF patients may be subclinically active for a long period of time and that it may contribute to a progressive decline in lung function. The identification of multifocal coexistent bronchiectasis, air-space disease, and nodules at CT should raise the possibility of atypical mycobacterial lung disease, even in an otherwise healthy patient.
