Mycobacterium intracellularis infection
Introduction
Introduction to intracellular mycobacterial infection Mycobacterium intracellular infection (Mycobacterium intracellulareinfection) pathogen Mycobacterium intracellulare was named by Runyon in 1967. The genus is slow-growing, non-photochromic, and the bacteria are short and can be separated from soil, water and animal waste. To that, infected birds, mammals, and guano-rich soils may be natural hosts for the bacteria. The bacteria can sometimes be isolated from the secretions of normal people, and the pathogenesis is still inaccurate. Mainly manifested as chronic lung infection, children with lymphadenitis, disseminated infection in immunosuppressed patients (especially AIDS), a large number of acid-fast bacilli can be found in secretions or biopsy smears, and bird branches can be found in culture examinations. Intracellular Mycobacterium growth, combined with better efficacy. basic knowledge The proportion of illness: 0.005% Susceptible people: no specific people Mode of infection: non-infectious Complications: abdominal pain, diarrhea, anemia
Cause
Causes of intracellular mycobacteria infection
(1) Causes of the disease
Mycobacterium intracellulare infection pathogen Mycobacterium intracellulare was named by Runyon in 1967. It is named for its presence in the cells of the lesion. The genus is slow-growing, non-photochromic, The bacteria are short, about 1~2m long, spherical, and can grow from 22 to 42 °C. Small, smooth and flat colonies can be formed from soil, water and animal excrement in 2 to 3 weeks. Infected birds. The species, mammals and guano-rich soil may be the natural host of the bacterium, which is sometimes isolated in normal human secretions.
(two) pathogenesis

Prevention
Intracellular Mycobacterium infection prevention
Pay attention to rest, work and rest, life in an orderly manner, and maintaining an optimistic, positive and upward attitude towards life can be of great help in preventing diseases.
Complication
Intracellular mycobacterial infection complications Complications abdominal pain diarrhea anemia
Generally no special complications
Symptom
Intracellular Mycobacterium infection symptoms Common symptoms Diarrhea, night sweats, abdominal pain
Mainly manifested as chronic lung infection, children with lymphadenitis, disseminated infection in immunosuppressed patients (especially AIDS), clinical manifestations of fever, night sweats, weight loss, encephalopathy, abdominal pain, diarrhea and anemia, skin performance similar In the case of leprosy, patients with immunosuppression can see abscesses or ulcers.
A large number of acid-fast bacilli can be found in the secretion or biopsy smear, and the growth of the bird branch or intracellular Mycobacterium can be found in the culture examination.
Examine
