Summary

Nontuberculous mycobacteria, once dismissed as contaminants, are now recognized as significant pathogens. Their prevalence increased dramatically with AIDS, particularly disseminated Mycobacterium avium complex (MAC) infections.

Area of Science:

  • Microbiology
  • Infectious Diseases
  • Immunology

Context:

  • Historically, nontuberculous mycobacteria (NTM) were often misidentified as contaminants.
  • Recognition of NTM as human pathogens emerged post-1950, primarily in individuals with pre-existing lung conditions.
  • The human immunodeficiency virus (HIV) epidemic significantly altered the landscape of NTM infections.

Purpose:

  • To review the epidemiological and clinical characteristics of nontuberculous mycobacteria (NTM).
  • To highlight the increasing role of NTM, particularly Mycobacterium avium complex (MAC), in human disease.
  • To discuss diagnostic, prophylactic, and therapeutic strategies for NTM infections.

Summary:

  • Nontuberculous mycobacteria (NTM) are increasingly recognized as significant causes of human disease.

  • The acquired immunodeficiency syndrome (AIDS) epidemic has led to a marked rise in disseminated NTM infections, especially MAC.
  • This review covers epidemiological trends, clinical presentations, and management considerations for NTM diseases, including the authors' clinical experience.

    • Impact:

    • Enhanced understanding of NTM as opportunistic pathogens, particularly in immunocompromised individuals.
    • Improved clinical awareness and diagnostic approaches for NTM infections.
    • Informed therapeutic strategies for managing NTM diseases, contributing to better patient outcomes.
