ABSTRACT: Information of susceptibility for the Mycobacterium leprae isolates is beneficial for the proven multi-drug treatment and for verification of the efficacy of current leprosy control program. The simple genotypic method to detect mutations conferring resistance to dapsone (DDS), rifampin, and quinolone was exploited on the basis of hybridization with capture probe fixed to the glass slide. Mutations were discriminated by a series of oligonucleotide probes corresponding to each mutation in the folP, rpoB, and gyrA genes of Mycobacterium leprae. Based on these mutations, gene contained these mutation points (hot spots) was amplified by polymerase chain reaction (PCR) and followed by dot blot hybridization to detect mutations. This method is simple, rapid and not very expensive. The result can be obtained within 8 hours. A total of 100 mutibacillary leprosy cases attending the Central Special Skin Clinic, Yangon General Hospital were determined gene mutations. Ninety-three cases (93%) were susceptible to three drugs and seven cases (7%) were resistant. Among resistant cases, 3 were DDS resistance, 1 was rifampicin resistance, 2 were quinolone resistance and 1 was both DSS and rifampicin resistance (MDR).
