"Atypical" mycobacterioses

D Y Rosenzweig

    Clinics in Chest Medicine
    |May 1, 1980
    PubMed
    Summary

    Atypical mycobacterial infections are increasing, often affecting compromised hosts but also healthy individuals. Current treatments are limited, highlighting the need for better therapies against these drug-resistant organisms.

    Area of Science:

    • Microbiology
    • Infectious Diseases
    • Clinical Medicine

    Background:

    • Atypical mycobacterial infections are rising in prevalence, partly due to improved diagnostics and a broader understanding of their diverse clinical presentations.
    • These infections range from pulmonary disease caused by MAIS to prosthetic joint infections linked to the Mycobacterium fortuitum complex.
    • Atypical mycobacteria are increasingly recognized as significant pathogens, necessitating a deeper understanding of their epidemiology and clinical impact.

    Purpose of the Study:

    • To highlight the growing importance of atypical mycobacterial infections.
    • To discuss the spectrum of diseases caused by these opportunistic pathogens.
    • To underscore the challenges in treating atypical mycobacterial infections due to drug resistance.

    Main Methods:

    • Literature review and synthesis of current knowledge on atypical mycobacteria.
    • Analysis of clinical manifestations and etiological agents.
    • Evaluation of therapeutic challenges and resistance patterns.

    Main Results:

    • Atypical mycobacteria are increasingly implicated in various infections, including pulmonary and prosthetic device-related diseases.
    • These organisms often act as opportunists, affecting individuals with compromised immunity, but can also cause severe disease in healthy hosts.
    • Atypical mycobacteria exhibit significant resistance to standard antituberculosis drugs, complicating treatment regimens.

    Conclusions:

    • Effective therapeutic strategies are available for some species like Mycobacterium kansasii.
    • There is a critical need for the development of more predictable, effective, and safer antimicrobial agents against a broader range of atypical mycobacteria.
    • Continued research is essential to combat the rising incidence and therapeutic challenges posed by atypical mycobacterial infections.
