Thirty-seven carcasses of Eurasian lynx (Lynx lynx) collected and examined in Estonia during 1999–2001 had helminths. Parasites identified and their prevalence included Diphyllobothrium latum (5%), Taenia pisiformis (100%), Taenia laticollis (41%), Taenia hydatigena (3%), Taenia taeniaeformis (3%), Toxocara cati (68%), and Trichinella spp. (22%). The only significant relationships (P≤0.05) between occurrence of helminths and host age and sex were a greater number of T pisiformis and T laticollis in older than in younger male lynx, and older males had a greater number of species of helminth than did younger lynx. Sixty-one fecal samples collected during snow tracking of nine lynx were examined; eggs of T. cati were identified in 38 samples, and Capillaria spp. were found in eight samples. This is the first systematic investigation of parasites of lynx in Estonia.
