Mycobacterium avium rough-to-smooth colony conversion resulting from growth in Tween 80 without presence of type-specific glycopeptidolipid antigens.
Growth of a Mycobacterium avium complex serotype 20 rough-colony variant in 1.0% Tween 80 resulted in a smooth-colony morphological conversion that was reversible upon removal of Tween and was not associated with the presence of serotype-specific glycopeptidolipid antigens. Electron microscopic examination suggested the role of an outer layer in the Tween-related morphological modification.
