Objective:To identify Leishman{u using PCR.Methods:This studs was conducted from April2009 to March 2011 in order to identify Leishmania species in a new endemic area of CL in Lorestan.Iran.Samples were taken from 62 patients that referred to the health centers in different cities of Lorestan province,the presence of Leishmcania was confirmed using direct smear and then grown in NNN media and mass cultured in RPM!1640 medium supplemented with 10%heat-inactivated fetal bovine serum.DNA was extracted from cultured promastigotes and used in P15-PCR.Results:45(72.6%)samples out of 62 showed a hand in the range of 485 hp and 17(27.4%)with a hand in the range of 626 hp which were similar to standard strains of Leichmania tropica(L.tropical and Leishnrania major(L.major),respectively.50(65.80%)of samples were collected from people with no history of travel in at least a year prior to the onset which shows that indigenous source of infection.Conclusions:Since the vector and reservoir of the two species are different.so precise and extensive control and prevention methods should be designed and earned out.
