Popis: The first part of this thesis is focused on testing the ability of selected European sand fly species to support the development of Leishmania major, L. donovani and L. martiniquensis. A total of 15 experimental infections were performed and 1601 female sand flies were analysed. The results show that Phlebotomus perniciosus and P. tobbi support development of L. major and L. donovani (mature infections with colonization of the stomodeal valve and metacyclic promastigotes developed), while L. martiniquensis did not survive defecation. The vector competence of Sergentomyia minuta to Leishmania could not be tested because the females of this species refused to take blood meal on feeders, although several types of membranes, blood and experimental conditions were tested. Further, biting midges were studied in two areas of Czech equine autochthonous cases of L. martiniquensis. A total of 3341 bloodfed and parous females from Slatiňany and 119 from Ústí n. L. were analysed. The most abundant were biting midges from the Culicoides obsoletus complex. None of the 97 pools were positive for Leishmania DNA, but in 15 pools from Slatiňany was detected DNA of Herpetomonas ztiplika and one pool from Ústí n. L. contained DNA of Trypanosoma sp. from T. theileri group. The isolation of L. martiniquensis was...
