Parasitological methods for the diagnosis of visceral leishmaniasis (VL) require invasive sampling procedures. The aim of this study was to detect Leishmania infantum (L. infantum) DNA by real time-PCR method in peripheral blood of symptomatic VL patient and compared its performance with nested PCR, an established molecular method with very high diagnostic indices. 47 parasitologically confirmed VL patients diagnosed by direct agglutination test (DAT > 3200), bone marrow aspiration and presented characteristic clinical features (fever, hepatosplenomegaly, and anemia) and 40 controls (non-endemic healthy control-30, Malaria-2, Toxoplasma gondii-2, Mycobacterium tuberculosis-2, HBV-1, HCV-1, HSV-1 and CMV-1) were enrolled in this study. SYBR-green based real time-PCR and nested PCR was performed to amplify the Kinetoplast DNA minicircle gene using the DNA extracted from Buffy coat. From among 47 patients, 45 (95.7 ) were positive by both nested-PCR and real time-PCR. These results indicate that real time-PCR was not only as sensitive as a nested-PCR assay for detection of Leishmania kDNA in clinical sample, but also more rapid. The advantage of real time-PCR based methods over nested-PCR is simple to perform, more faster in which nested-PCR requires post-PCR processing and reducing contamination risk. © 2014, Indian Society for Parasitology.
