During the years 2015—2016 we obtained 15 samples of faeces of brown bears (Ursus arctos) and 2 samples of gastrointestinal (GI) tracts of young female brown bears for helminthological examinations. The samples of faeces were collected from various sites in the protected landscape area CHKO-Poľana, and the gastrointestinal tracts originated from bears hunted down in the same area within permitted regulation of bear population for 2015. Of the 17 samples collected from the CHKO-Poľana area, 13 were positive for the presence of parasites (76.47 %). Parasitological examinations revealed the presence of 5 species of endoparasites: Eimeria, Cryptosporidium, Sarcocystis, Baylisascaris and Ancylostoma. Roundworms Baylisascaris transfuga (46.15 %) and Ancylostoma spp. (30.77 %) were the dominant species. Observation of the seasonal dynamics showed the highest prevalence of parasites during autumn and winter.


The aim of the study was monitoring of liver flukes in wild ruminants including red deer (Cervus elaphus), roe deer (Capreolus capreolus), fallow deer (Dama dama) and mouflon (Ovis musimon) in selected regions of Slovak Republic. Between 2014 – 2016 we examined 782 faecal samples from selected wild ruminants using coprological techniques and serological methods (ELISA detection of F. hepatica coproantigens). None of the samples was positive for the presence of Fasciola hepatica, 5.89 % of faecal samples were positive for Dicrocoelium dendriticum. Higher prevalence was recorded in mouflon (30.83 %), lower in red deer (1.49 %). D. dendriticum infection was not determined in fallow deer and roe deer. The seasonal distribution of dicrocoeliosis indicated a highest prevalence in autumn. Significantly higher prevalence was recorded in fenced rearing when compared with open hunting grounds, suggesting that animal agglomeration, constant use of the same areas and possible stress are the main risk factors. Parasitological examination of livers of hunted wild ruminants revealed dicrocoeliosis in mouflon.
