Small terrestrial mammals (Rodentia, Eulipotyphla) and their ectoparasites (Siphonaptera, Acari: Mesostigmata a Ixodidae) form a natural part of the fauna of the Danubian Lowland. Species richness, abundance and infestation of ectoparasites were studied. Capturing of small terrestrial mammals was realized in 5 localities (9 lines), in the years 2014 – 2015. Overal 931 specimens of 12 small terrestrial mammals were captured, from which 287 specimens (31%) were positive for ectoparasites. We obtained 1 599 specimens of 27 species of ectoparasites from the Siphonaptera (190 ex., 6 sp.), Acari: Mesostigmata (1 338 ex., 19 sp.) and Ixodida (71 ex., 2 sp.) groups from their fur. Common vole was the most commonly captured species and host of the largest number of species and specimens of all ectoparasites´ groups.
