Mycobacterium tuberculosis - Tuberculosis

Mycobacterium tuberculosis is the bacteria that causes tuberculosis (TB), an infection that usually affects the lungs and can be fatal without proper treatment. Nontuberculosis mycobacteria (NTM) can also be pathogenic agents in humans. Screening for latent TB involves either the interferon-gamma release assay or the tuberculin skin test (TST). Diagnostic tests for active infection include acid-fast bacilli (AFB) smear and nucleic acid amplification testing (NAAT), with culture providing definitive diagnosis.
