title: Identification of cutaneous Leishmaniasis vectors, Phlebotomus papatasi and P. duboscqi using random amplified polymorphic DNA.
abstract: Phlebotomus papatasi and P. duboscqi are two closely related, morphologically similar sandfly species that are established vectors of zoonotic cutaneous leishmaniasis in the Old World. We have developed a Random Amplified Polymorphic DNA (RAPD) method to find species-specific DNA profiles of these two species. It was found that using a single 10-mer primer a 'species specific' amplification band of about 0.49 kb was produced in all specimens of P. duboscqi while it was absent in P. papatasi. The 0.49 kb diagnostic band was consistently present in both males and females of P. duboscqi. The suitability of this primer for Phlebotomus species identification will help to find the true vector-parasite relationship in the epidemiology of leishmaniasis, particularly in the African countries where both species are prevalent.
