Sažetak
In this study we investigated the prevalence of the maedi-visna virus for the first time in Croatia. During 2013 a total of 408 randomly selected sheep and rams blood serum samples were collected from flocks located in four counties in the Dalmatia region, on the eastern coast of the Adriatic Sea. All sera samples were tested using the gel diffusion precipitation test. The presence of maedi-visna virus infection was serologically confirmed in 66 out of 408 tested animals (16.18%). The highest seroprevalence was confirmed in central Dalmatian counties - with seroprevalence of 21.5% in Sibenik-Knin and 20.16% in the Split-Dalmatia County. In the Dubrovnik-Neretva County, in the southernmost part of Dalmatia, no positive samples were found. These results represent the first evidence of maedi-visna virus circulation in sheep in the Republic of Croatia. Given the economic losses that maedi-visna inflicts upon sheepherding, the study results indicate a need for immediate implementation of effective administrative veterinary measures, aimed at preventing and controlling this infection in the Adriatic part of Croatia.
