The objective of this study was to determine the frequency of animals that tested positive for brucellosis and leptospirosis and the risk factors for these diseases in the State of Paraíba. A total of 136 buffaloes from 14 herds were examined. For brucellosis, we used the buffered acidified plate antigen (BAPA) test as screening method and 2-mercaptoethanol as confirmatory test. For leptospirosis, we conducted a microscopic agglutination test (MAT), with a cut-off point of 1:100. Of the animals

The brucellosis-positive animals were from two (14.3%) herds, while nine (64.3%) herds had leptospirosis-seropositive animals. The more frequent Leptospira spp. serotypes were Bratislava, Pomona, and Canicola. We concluded that leptospirosis was widespread in buffaloes in the state of Paraíba and suggested that breeding alongside horses and pigs might be an important factor in the spread of leptospirosis-positive animals. The presence of brucellosispositive animals indicated the possibility of negative-impacting measures on disease control in bovines, and it is therefore recommended that greater attention be given to these animals for brucellosis control. Brasil, A. W. de L. et al. = 21,1% -36,0%) para leptospirose. Os animais positivos para brucelose foram procedentes de duas (14,3%) propriedades, enquanto para leptospirose nove (64,3%) propriedades apresentaram animais soropositivos. Os sorovares de Leptospira spp. mais frequentes foram Bratislava, Pomona e Canicola. Conclui-se que a leptospirose encontra-se disseminada em búfalos do Estado da Paraíba, e sugere-se que a criação consorciada com equinos e suínos pode ser um fator importante na ocorrência de animais positivos. A presença de animais positivos para brucelose indica a possibilidade de impacto negativo nas ações de controle da doença em bovinos, e dessa forma recomenda-se que maior atenção seja dada a esses animais do ponto de vista do controle da brucelose.
