A genotypic method for predicting rifampicin resistance in Mycobacterium leprae has been developed and rigorously tested on mouse footpad-derived and clinical specimens. A series of immobilized oligonucleotide capture probes can discriminate between wild type and mutant rpoB alleles, and positive controls are available for the most frequent mutation affecting Ser425. Two different nonradioactive detection formats have been tested with comparable success in both an industrialized and a developing country. The standardized procedure could now be used in a prospective study of potential rifampicin resistance among multibacillary patients.
