Typical and atypical mycobacterial infections show a dramatic increase among acquired immune deficiency syndrome patients despite highly-active antiretroviral therapy.

Here, we present the first case in which both Mycobacterium gastri and Mycobacterium tuberculosis were isolated in the same specimen (ie, sputum).
