A review of leishmaniasis in Dalmatia (Croatia) and results from recent surveys on phlebotomine sandflies in three southern counties

Zoonotic visceral leishmaniasis (VL) is a re-emerging disease in the Mediterranean area. A historical review on human and canine leishmaniasis in Croatia documents the presence of stable disease foci in coastal and insular territories of central and southern Dalmatia since the beginning of the 20th century. We report on a 3-year entomological investigation (2002–2004) aimed to study the current species composition and seasonality of phlebotomine sandflies in 10 localities of Dalmatia. Standard blacklight traps employed for sampling Culicoides midges in the frame of bluetongue disease surveillance were used for the first time in phlebotomine monitoring. A total of 2917 sandflies were collected and five species were identified, Phlebotomus tobbi, Phlebotomus neglectus, Phlebotomus perfiliewi, Phlebotomus mascittii and Sergentomyia minuta. Among the species, which may act as Leishmania infantum vectors, P. tobbi and P. neglectus were the most abundant.
