Internal parasites in roe deer of the Lubartów Forest Division in postmortem studies
The aim of the study was to analyze endoparasitic fauna in roe deer of a selected area of south-western Poland using coproscopic studies and postmortem studies of internal organs (lungs, livers and digestive tracts). Microscopic methods included flotation and the McMaster method. In May and June 2015, 53 culled male roe deer were examined. Parasites were found in 96.2% (n=51, SD=19.2) of the studied animals, but the invasion intensity was diversified. From 1 to 7 different taxa (families or genera) of parasites were found in each studied animal. Oocysts of Eimeria (3 species (E. capreoli, E. panda, E. rotunda) were found with the following invasion prevalence: 45.28%, low OPG level, in the range of 350-700. In three samples, the OPG amounted to 2800–4500. Cysts of Buxtonella sulcata 9.4% (CPG in the range of 300–100). Fasciola hepatica (prevalence 3.77%), intensity: 2–3 specimens, Dicrocoelium dendriticum (5.66%), intensity: 2–5 specimens. Moniezia expansa (7.54%), intensity: 3–8 tapeworms. Nematodes from the family Trichostrongylidae (58.49%, genera: Ostertagia, Spiculopteragia, Haemonchus, Trichostrongylus and Nematodiurus from the family Molineidae), low invasion intensity (8–55 nematodes), only in 7 deer intensities of 346–140 nematodes). Capillaria bovis (7.54%) intensity ranging from 2 to 14 nematodes. Oesophagostomum venulosum (15.09 %) invasion intensity: 7–23 nematodes, Trichuris globulosa (9.43%), invasion intensity 2–4 nematodes. Dictyocaulus eckerti (11.32%), invasion intensity ranging from 6 to 34 nematodes. Setaria tundra (5.66%) invasion intensity ranging from 1 to 3 nematodes.
Key words: wild ruminants, roe deer, coccidian, gastrointestinal parasites.
