Abstract
ObjectiveTo identify and study the epidemiology of Leishmania species isolated from patients with leishmaniasis by PCR method in Sabzevar, Khorasan Razavi Province, Iran. MethodsAspirated samples from the lesions of 86 patients with confirmed leishmaniasis used for direct smear preparation. The samples are prepared and cultured in the Novy-MacNeal-Nicolle and Roswell Park Memorial Institute-1640 culture mediums. After extraction of DNA by using phenol-chloroform, parasite kintoplast DNA gene amplification was done by using PCR. The electrophoresis pattern of each species was compared with standard species of Leishmania tropica (L. tropica) and Leishmania major (L. major). ResultsResults of PCR patterns of kintoplast DNA gene suggested that two types of L. tropica and L. major isolated from leishmaniasis patients in Sabzevar and their findings indicated that both species of parasites, L. tropica and L. major are prevalent in Sabzevar. ConclusionsAccording to this information, Sabzevar can be divided in two focal points of dry and dry-wet in terms of leishmaniasis, while it was previously known as the dry focal point. Likewise a significant relationship observed between Leishmania species to time distribution, type of lesion, amount of parasites and infection districts.
