Abstract
Introduction Leishmania donovam, the causative agent of visceral leishmaniasis in the Indian subcontinent, has been reported to be genetically homogeneous In order to support ongoing initiatives to eliminate the disease, highly discriminative tools arc required for documenting the parasite population and dynamics Methods. Thirty-four clinical isolates of L donovam from Nepal were analysed on the basis of size and restriction endonuclease polymorphisms of PCR amplicons from kinetoplast minicircle DNA, 5 nuclear microsatellites, and nuclear loci encoding glycoprotein 63, cysteine proteinase B, and hydrophilic acylated surface protein B We present and validate a procedure allowing standardized analysis of kDNA finger print patterns Results. Our results show that parasites ale hest discriminated on the basis of kinetoplast minicircle DNA (14 genotypes) and I microsatellite defining 7 genotypes, while the remaining markers discriminated 2 groups or were monomorphic Combination of all nuclear markers revealed 8 genotypes, while extension with kDNA data yielded 18 genotypes Conclusion. We present tools that allow discrimination of closely related L donovam strains circulating in the Teran region of Nepal These can be used to study the micro-epidemiology of parasite populations, determine the geographical origin of in distinguish relapses from re-infection, and monitor the spread of particular variants
