SEROPREVALENCE OF SALMONELLA SPP. ON IMPORT BOARS FROM DENMARK TO SERBIA

The sera from 120 boars from 3 farrow-to-finish swine herds in Serbia were examined for Salmonella spp. antibodies in a cross-sectional study using an ELISA test. A total of 120 blood serum samples from boars imported from Denmark were examined. All boars were seronegative to Salmonella during the import, while after one year Salmonella spp. seroprevalence ranging from 0% to 45% was found in 3 herds using two tests in the time span of one year. Only on one farm during the import in 2011, after a year boars were still seronegative. A year later on the same farm, in boars imported in 2012 the seroprevalence was 30%. Seroprevalence of Salmonella spp. in boars tested on all farms was 24,17%.
