ABSTRACT:   Currently recommended control measures for treating leprosy with multi-drug therapy (MDT) should control the spread of drug resistant strains; however, dapsone (DDS) resistance continues to be reported. Compre-hensive estimates of drug-resistant leprosy are difficult to obtain due to the cumbersome nature of the conventional drug susceptibility testing method using mouse footpad inoculation, which requires at least 6 months to obtain results. Recently, it has been determined that DDS resistant strain contains missing mutations in codon 53 and 55 of the fol P1 gene of Mycobacterium leprae, and definitive evidence linking these mutations with DDS resistance in M. leprae has been obtained. Based on these mutations, fol P1 gene contained these mutation points (hot spots) was amplified by polymerase chain reaction (PCR) and followed by sequencing to detect mutations. A total of 50 multibacillry leprosy cases before MDT treatment attending Central Special Skin Clinic, Yangon General Hospital were determinedfol P1 gene mutations. DDS resistance was detected in four cases (8%). This study is part of the detection of multi-drug resistant leprosy in Myanmar.
