The prevalence of Trichinela britovi among different populations of wolves in Croatia

The aim of the present study was to investigate the prevalence of Trichinella infection in wolves (Canis lupus) among geographicaly distinct populations permanently present on 17468 km2 with 120 to 170 individuals. The studied regions were Gorski Kotar, Lika and Dalmatia. Muscle samples were collected from 33 wolves killed between 1996. and 2004. and analysed by artificial digestion. The muscle larvae were also typed by the multiplex PCR method. Trichinella britovi was the only species with the prevalence of 27, 27 %. Infection rate was from 0, 3 to 45, 9 larvae per gram. Geographical distribution of infected animals varies. No infected animals were found in the region of Gorski Kotar. The wolves from the region of Lika were all found infected. The prevalence of Trichinella in wolves from Dalmatia was 13, 04%. The wolf that was killed near Zagreb was also found positive. In this article we have compared eating habits, density of wolves, and posible impact of people on Trichinella distribution among different populations of wolves in Croatia.
