Infections due to non-tuberculous mycobacteria

Definition

Acid-fast mycobacteria other than M. Tuberculosis and M. leprae are ubiquitous and can cause a range of diseases in humans. They are known collectively as non-tuberculous or atypical mycobacteria. Disseminated infection is usually a consequence of profound immunosuppression such as that due to AIDS. The commonest presentation, however, is with localized or regional cutaneous infection. A wide variety of other presentations may be seen, amongst which lymphadenitis and pulmonary disease are prominent.
