Abstract

Summary: Electroporation with shuttle plasmids carrying a kanamycin resistance gene as a selectable marker failed to generate transformants in two mycobacterial species currently being used in human vaccine trials ( and vaccae). In contrast, efficient transformation [10-10 transformants (μg DNA)] was obtained using novel vectors with selection based on expression of resistance to hygromycin. The hygromycin resistance vector was also found to be more efficient than kanamycin resistance vectors for transformation of and . The hygromycin resistance vector was used to overexpress superoxide dismutase of in in a form suitable for detailed structural analysis. The potential use of this approach for generation of novel recombinant mycobacterial vaccines is discussed.
