- <p>In the period of 1998-2001 internal organs obtained from 45 wild boars and 21 roe deer, as well as 136 faecal samples from pheasants in the Tisnovsko discrict were examined for parasites. The animals had been partly shot and partly had died in various localities. Parasite fauna of wild boars (Sus scrofa): all of 45 animals were up to a year old, prevalences were 35.6% for <em>Eimeria</em>/<em>Isospora</em>, 2.2 % for <em>Ascaris suum</em>, 17.8 % for <em>Trichuris suis</em>, 31.1% for <em>Metastrongylus confusus</em>. <em>Trichinella spiralis </em>and trematodes were not found. Parasite fauna of roe deer (<em>Capreolus capreolus</em>): total prevalence 73%, 26% for <em>Eimeria </em>spp, 51% for <em>Ostertagia</em> spp., 32% for <em>Trichuris</em> spp., 62% for <em>Chabertia </em>spp., 28.4% for <em>Trichostrongylus</em> spp., 9.5% for <em>Oesophagostomum</em> spp., 14% for <em>Haemonchus contortus</em>, 28.6% for <em>Moniesia benedini</em>, 38% for <em>Capreocaulus capreoli</em>, liver and rumen flukes were not found. Parasite fauna of pheasant (<em>Phasianus colchicus</em>): 48.6% of pheasants were infected. Prevalences were together 36.6% for <em>Eimeria phasiani</em>, <em>E. colchici</em>, and <em>E. duodenalis</em>, other pheasant specific parasites have not been found. Next 12.9% for <em>Capillaria </em>spp., 5.8% for <em>Syngamus trachea</em>, and 23.2% for <em>Meterakis gallinarum</em>. Quantitative analysis of infections in game animals showed that gastrointestinal helminths were not a cause of mortality in spite of the fact that there is a difference between the animals originated from the different hunting areas. Our results support the hypothesis that human disturbances and overgameing lead to higher parasite loads on game animals populations. Studying game animals over a few years showed, that there is a tendency of the health status of animals is getting worse. However, the most important reason of losing animalsis not parasites, but above all the decreasing ecological balance,poisonings caused by chemicals used in field sprays and in wild boars killing of the up to a year old sow with young.</p>
