Sera of 4407 wild boars (Sus scrofa) shot by hunters in Poland in 2012 were tested by ELISA for antiBrucella antibodies. Samples originated from 11 out of 16 voivodeships, and 1077 (24.44%) seroreagents were detected. The highest prevalence of wild boars with anti-Brucella antibodies was found in Opolskie (39.9%) and Wielkopolskie (37.29%) voivodeships. The lowest percentage of positive results was observed in Kujawsko- -Pomorskie (13.74%) and Łódzkie (15.47%) voivodeships. The results for particular districts revealed significant differences in the prevalence of anti-Brucella antibodies, which varied between 0 and 100%. The results of the surveys show that wild boars constitute an enormous reservoir of Brucella suis biovar 2 microorganisms in Poland. The next stage of the study will see examinations of wild boars continued by bacteriological and molecular methods.
