Mycobacterium intracellular infection

Mycobacterium intracellulare infection is a pathogen that was named by Runyon in 1967. This genus is a slow-growing, non-photochromogenic bacterium that is short and can be excreted from soil, water, and animals. It was found that infected birds, mammals, and guano-rich soil may be natural hosts for the bacteria. The bacteria can sometimes be isolated from normal human secretions. The pathogenesis is uncertain. Mainly manifested by chronic lung infections, children with lymphadenitis, and immunosuppressed patients (especially AIDS) have disseminated infection. A large number of acid-fast bacilli can be found in secretions or biopsy smears, and cultures can show the growth of bird or intracellular Mycobacterium The combination of drugs is effective.
