ABSTRACT:   Eighty two skin biopsy specimens from leprosy patients attending at Central Special Skin Clinic, Yangon General Hospital were collected before taking chemotherapy. They were examined by a two-step polymerase chain reaction assay using a set of four nested oligonucleotide primers for the detection and identification of Mycobacterium leprae. It did not require the use of radioactively labelled hybridization probes. The nested-primer procedure amplified a 347base-pair product from M. leprae genomic DNA. The PCR results were then compared with bacterial indices (BI) of slit-skin smears. PCR was positive in 8 (80%) of 10 biopsy specimens with BI of 0 determined for the slit-skin smear from the same patients. PCR also gave positive results for 71 (98.6%) of 72 BI positive cases. The agreement rate of these two tests is 89% but the false negative rate of BI for diagnosis of leprosy compared to PCR method is 10.39%. According to these results, PCR has an advantage over microscopic examination in detecting M. leprae in biopsy specimens negative for acid-fast bacilli, and is a useful tool for laboratory diagnosis.
