Abstract

Research of anti-smooth brucella antibodies in pigs slaughtered at the Patos Public Slaughterhouse, State of Paraíba. The seroprevalence of brucellosis was determined in pigs slaughtered at the Public Slaughterhouse in Patos, State of Paraíba. For this purpose, 306 serum samples were collected from February to June 2007. For the serological diagnosis of swine brucellosis, the Buffered Acidified Antigen (AAT) test was used with the buffered Acidified Antigen test, from the 306 pigs analyzed, three were seropositive (0.98%; 95% CI = 0.20% - 2.84%). Of the 124 male pigs, one (0.81%; 95% CI - 10.02% - 4.41%) was seropositive, while two (1.10%; 95% CI = 0.13% - 3.91% ) of the 182 females were seropositive. In the 2-mercaptoethanol test, of the three reactive samples in the AAT, two (0.65%; 95% CI = 0.08% - 2.34%) were confirmed as positive. All 2ME positive samples were females, however, no significant difference was observed in the proportion of seropositives between males and females (p = 0.516).
