RESUMO
Leishmaniasis is an arthropod borne disease that is endemic in 102 countries and one and half million new cases are reported each year. Sand flies are the one and only proven vectors of the disease and dogs are the main reservoirs in urban areas. Karaburun peninsula is located in most western part of Turkey and is reported to be an endemic area for human and canine leishmaniasis. The most recent study was undertaken more than 15 years ago in The peninsula and no clear data available for vectors or reservoirs. Thus, we aimed to update the information regarding sand fly diversity, infection status of reservoirs and vectors in the study area. Sand flies were collected using CDC light traps at 13 different sites of Karaburun and species identification was made using previously published keys. Monospecific pools were generated using midguts with blood retention and were screened for the presence of Leishmania spp. DNA by molecular techniques. A non-invasive conjunctival swab sampling was performed to identify the infection status among reservoirs and species typing of the causative agent was also undertaken using ITS1 PCR. Three out of 30 pools were found positive for Leishmania infantum that were generated using guts of Phlebotomus tobbi (n:36). Among all sampled dogs (44) and cats (19), 11 and one of them were found positive for L. infantum, respectively. There was a decrease in the number of P. papatasi during the study period, while increase was observed in the number of P. tobbi. The presence of proven vectors and reservoirs as well as Leishmania DNA in cats was shown in the present study. Sand fly fauna is updated and Leishmania DNA presence in cats was reported in the study area for the first time.
