Nontuberculous mycobacterial disease

Non tuberculous mycobacteria refer to mycobacteria in the genus mycobacteria, except Mycobacterium tuberculosis complex (human, bovine, African and vole Mycobacterium tuberculosis) and Mycobacterium leprae. The disease caused by NTM is called non tuberculous mycobacterial disease. In recent years, due to the increasing detection rate, the corresponding understanding of various diseases caused by it is also gradually improving. Most of non tuberculous mycobacteria are rot parasitic bacteria with low virulence and belong to conditional pathogens. The symptoms of non tuberculous mycobacterial disease can be divided into intrapulmonary and extrapulmonary. Extrapulmonary infection can involve skin, bone and lymph nodes.
