Non-tuberculous mycobacteria usually refers to non-tuberculous mycobacteria, which can be cured in most cases, but treatment is difficult and takes a long time. Non-tuberculous mycobacteria are widely found in the natural environment, such as soil, swimming pools, bathtubs, and dust. People mainly get infected with non-tuberculous mycobacteria from the environment and become ill, which can invade the lungs, skin, bone tissue, lymph nodes and other parts of the body. Infection with Mycobacterium non-tuberculosis can be cured in most people with regular treatment. Mycobacterium non-tuberculosis is resistant to commonly used antimycobacterial drugs, so the treatment of Mycobacterium non-tuberculosis requires a combination of drugs and a relatively long treatment period, commonly used drugs include: clarithromycin, azithromycin, rifampicin, linezolid, and so on.
