Brucellosis was confirmed in boars imported for breeding purposes to Poland from one of the EU countries. In serological investigations, in which the RBT, ELISA, CFT, SAT and 2-ME were used, positive reactions to brucellosis were found in 9 out of 23 animals. All the animals were slaughtered, and bacteriological examination was performed. Brucellae were isolated from the tissues of 7 boars. The characteristics of the strains isolated showed that they belonged to Brucella suis biovar 2, which is typical for Europe. The examination of animals for brucellosis at quarantine stations seems to be crucial for the protection of herds from Brucella infection.
