Za određivanje općega zdravstvenoga stanja glavnih vrsta plijena vuka (Canis lupus) i risa (Lynx lynx), pretraženo je 66 cervida (41 jelen - Cervus elaphus i 25 srna - Capreolus capreolus), odstrijeljenih u dva lovišta na području Gorskoga kotara tijekom lovne sezone u 2007. godini. Sakupljeno je ukupno 687 uzoraka organa, od čega je 427 bilo od jelena, a 215 od srna. Provedene su pretrage na razne parazitske invazije, nespecifične bakterijske infekcije, te za tri specifične bakterijske infekcije. U pet (12,2%) uzoraka jelena i sedam (17,1%) srna bio je prisutan Streptococcus sp. Testovi na Mycobacterium sp., Brucella sp. i Leptospira sp. bili su negativni. Zastupljenost parazita Dictyocaulus spp., Ostertagia spp. i Elaphostrongylus cervi u jelena bila je 29,3%, 17,1%, odnosno 14,6%. Zastupljenost parazita Chabertia ovina, Ostertagia spp. i Trichostrongylus spp. u srna bila je 36,0%, 24,0% odnosno 20,0%. Procijenjeni broj jelena i srna u lovištima Smrekova Draga (182 km2) i Bjelolasica (303 km2) u lovnoj godini 2007./2008. bio je 430 odnosno 290, s gustoćama od 236 i 148 jedinki na 100 km2. Niska zastupljenost parazitarnih invazija i odsutnost ozbiljnijih bakterijskih zaraza, bile su posljedica niske gustoće parnoprstaša i prisutnosti velikih zvijeri - grabežljivaca koji hitro uklanjaju životinje oslabljene bolešću. To determine the general health status of the main prey species of wolf (Canis lupus) and lynx (Lynx lynx), we examined 66 cervids (41 red deer - Cervus elaphus and 25 roe deer - Capreolus capreolus), shot in two hunting areas of Gorski kotar during the hunting season in 2007. We collected a total of 687 organ samples of shot deer, where 472 samples belonged to red deer and 215 samples to roe deer. Analyses were performed for various parasite invasions, non specific bacterial infections and for three specific bacteria. In five (12.2%) samples of red deer and seven (17.1%) roe deer, we determined the presence of Streptococcus sp. Specific tests for Mycobacterium sp., Brucella sp. and Leptospira sp. were all negative. The prevalence of Dictyocaulus spp., Ostertagia spp. and Elaphostrongylus cervi in red deer was 29.3%, 17.1% and 14.6%, respectively. The prevalence of Chabertia ovina, Ostertagia spp. and Trichostrongylus spp. in roe deer was 36.0%, 24.0% and 20.0%, respectively. The estimated number of red deer and roe deer in the hunting areas Smrekova Draga (182 km2) and Bjelolasica (303 km2) in the management year 2007-2008 were 430 and 290 respectively, with densities of 236 and 148 individuals per 100 km2. The low prevalence of parasite invasions and the absence of serious bacterial infections were the consequences of low ungulate densities, and the presence of large carnivores - predators that quickly eliminate animals weakened by disease.
