Sand flies (Diptera, Phlebotominae) are small biting insects and vectors of Leishmania spp. which cause medically and veterinary important disease - leishmaniasis. During the piercing of the host skin, sand fly females inject saliva to facilitate the blood feeding. The sand fly saliva is composed of many bioactive molecules which were shown to possess anti-inflammatory and anti-haemostatic functions. The saliva affects host's immunity in the bite site and consequently enhances the survival and development of transmitted pathogens. Most of the studies focus on salivary proteins and enzymes of sand flies belonging to Phlebotomus and Lutzomyia genera, while salivary proteins from sand flies of the third genus Sergentomyia were neglected so far. In this thesis we focused on comparison of salivary proteins from two Phlebotomus species, namely Phlebotomus perniciosus and Phlebotomus orientalis, and Sergentomyia schwetzi. These sand fly species differ not only by the ecology and geographical distribution but also by host preferences. Both Phlebotomus species prefer large or medium-size mammals as the bloodmeal source, particularly rabbits, hares and dogs for P. perniciosus and cattle, goats, sheep and humans for P. orientalis. Contrarily, Sergentomyia sand flies are known for preferred feeding on reptiles...
