The aim of this investigation was to evaluate the seropositivity for brucellosis in pig slaughterhouses. Sera of 910 pigs from 30 farms and slaughtered at slaughterhouses, located in the central region of the state of São Paulo, were tested with Buffered Plate Acidified Antigen (BPAA) and 2-mercaptoethanol (2-Me) as confirmatory test to determine the serological positivity in this species. The results demonstrated that 25 (2.7%) of the pigs from 10 farms reacted to BPAA, corresponding to 36% of positive properties. From BPAA positive animals 16% and 52% presented titers of 25 incomplete and 25 respectively in the Tube agglutination test (TAT), 8% presented 50 and 25 incomplete, respectively, in TAT and 2-ME, and 8% resulted 50 and 25 positive in TAT and 2-ME, respectively. These results demonstrate the high percentage of positive farms for swine brucellosis in this region and reinforce the need for official and effective program implementation for the swine brucellosis control. |
