    Six years ago, Michael Niederweis, Ph.D., described the first toxin ever found for the deadly pathogen Mycobacterium tuberculosis. This toxin, tuberculosis necrotizing toxin, or TNT, became the founding member of a novel class of previously unrecognized toxins present in more than 600 bacterial and fungal species, as determined by protein sequence similarity. The toxin is released as M. tuberculosis bacteria survive and grow inside their human macrophage host, killing the macrophage and allowing the escape and spread of the bacteria.
