Abstract
Cutaneous leishmaniasis (CL) is a vector-borne disease widely distributed in tropical and subtropical areas of North and South America, Europe, Asia, and Africa. Considering the increasing number of CL cases in recent years and the fact that no study has been conducted to identify CL fauna and vectors in Alborz province, this study was carried out to identify sand flies and CL vectors in this region. Sand flies were collected from August to October 2021 from plain and mountainous indoor and outdoor areas of the region using sticky paper traps and were detected morphologically. DNA was extracted from the midguts of female sand flies. In this study, 1157 sand flies were collected and identified. The number of sand flies caught from indoor and outdoor places was 367 (31.72%) and 790 (68.28%), respectively. Overall, six species of flies were of the genus Phlebotomus (Raynal, 1937), including Phlebotomus papatasi (P. papatasi, 695 [60.07%]; Scopoli, 1786), P. kandelakii (13 [1.12%]; Shchurenkova, 1926), P. sergenti (232 [20.05%]; Parrot, 1917), P. major (14 [1.21%]; Annandale, 1910), P. caucasicus (4 [0.35%]; Marzinowsky, 1917), P. alexandri (18 [1.56%]; Alexandri Sinton, 1920), and four were of the genus Sergentomyia (Artemiev, 1978), including Sergentomyia tiberiadis (109 [9.42%]; Adler, Theodor & Lourie, 1930), Sergentomyia baghdadis (53 [4.58%]), Sergentomyia sintoni (14 [1.21%]; Sintoni Pringle, 1933), Sergentomyia clydei (5 [0.43%]). P. papatasi spp. were dominant in indoor and outdoor places, with a prevalence of 695 (60.07%). The Leishmania major (L. major) gene was identified in five samples of P. papatasi spp. This suggests that P. papatasi is the potential vector spp. in the study area. Moreover, L. major was confirmed as the aetiological agent of CL cases in Alborz province. The identification of vectors and parasite spp. is very important for the treatment and operational planning of disease vectors.
