 AB    Both smooth transparent (SmT) and smooth domed-opaque (SmD) colonial
       variants were obtained from a strain of Mycobacterium avium isolated
       from a patient with AIDS. The two variants showed similar biochemical
       characteristics but SmT bacteria proliferated better than SmD bacteria
       inside human macrophages and were much less capable than the SmD variant
       of inducing the release of IL-1 beta, IL-6, TNF-alpha, GM-CSF and G-CSF,
       after incubation for either 3 or 6 days. As cytokines are important
       extracellular signals for immune cells, the lack of induction observed
       in SmT-infected macrophages may be one of the pathogenic mechanisms of
       M. avium.
