The objective of this study was to determine the prevalence of anti-Brucella antibodies in feral pigs and bovines simpatrics in the Pantanal subregions of Paiaguás and Nhecolândia. The study was conducted in the municipality of Corumbá, Mato Grosso do Sul State, Brazil. A total of 105 feral pigs and 256 cattle were sampled in 12 farms, in all animals blood samples were collected for the serological diagnosis with Rose Bengal Test (RBT) for screening, 2-Mercaptoethanol (2-ME) confirmatory test and comparative test with Fluorescence Polarization Assay (FPA). The prevalence of positive feral pigs were 1% (1/105) in the RBT and FPA and no positive AAT results were confirmed in the 2-ME test. The prevalence of positive cattle sampled was 11.32%, 4.3% and 7.42% in the RBT, 2-ME and FPA tests respectively. The degree of agreement obtained between the serological tests used in cattle was Kappa = 0.506 (p <0.001), 95% CI (0.282 - 0.729). The results of the serological tests demonstrated that brucellosis is widespread in bovine herds of the region studied, but the same type of exposure to the agent did not occur in feral pigs according to the diagnostic tests used.
