Abstract:   (1722 Views)
We describe a rapid, simple, and reliable procedure for routine isolation of Mycobacterium leprae DNA from slit-skin swab specimens. This one-step DNA extraction method is based on the utilization of ChelexR 100, a chelating ion exchange resin. Slit-skin swab specimens from seven untreated leprosy patients at Baba Baghi Leprosy Hospital in Iran were processed by this procedure. The polymerase chain reaction (PCR) was performed with primers for a 530-base pair (bp) fragment of the gene encoding the 36 kDa antigen of M. leprae. All the specimens were found to be PCR -positive, suggesting the efficiency of the present DNA extraction method.
