[The serological and entomological survey of zoonotic visceral leishmaniasis in Ayvacik Region of Canakkale Province, Turkey].

The field studies were carried out in Ilyasfaki village belonging to Ayvacik town, Kalabakli village and center of Kepez town belonging to Canakkale province to determine the epidemiological situation of visceral leishmaniasis between June and August 2007. A total of 27 blood samples were taken from the dogs which are known as reservoir of Leishmania infantum causing visceral leishmaniasis in human and dogs. The dogs were also examined physically for clinical symptoms of the disease. A total of 789 sand fly specimens were collected using CDC miniature light traps and examined. Six Phlebotomus and one Sergentomyia species were identified as: Phlebotomus negletus, P. tobbi, P. simici, P. papatisi, P. perfiliewi, P. halepensis and S. theodori. Among these species P. neglectus, was found to be a dominant species in Ilyasfaki village by the rate of 94.4%, while P. tobbi was also found to be a dominant species in city center (including Kepez) and Kalabaki village by the rate of 50% and 48.1%, respectively. No seropositive dogs were found by IFA test. Seropositivity below cut-off level was only observed in two dogs from Kepez, in dilutions of 1/16 and 1/64. The risk level for human and canine visceral is found to be high and it requires more field studies on canine leishmaniasis in and around the area.
