Resumo: A serosurvey was conducted to estimate the prevalence of bovine brucellosis in the State of Paraíba, Brazil. A random sample of six municipalities was selected from each of three ecoregions of the State: the Agreste/Litoral region (1), the Cariri/Curimatau region (2) and the Sertão region (3). These 18 municipalities were divided in quadrants and one herd was selected at random from each quadrant. The sampling scheme included herds with more than 50 bovines, which excludes small-holder subsistence livestock production. At least 32 animals were sampled within each herd, stratified in four age categories, as follows: (1) at least 8 animals under 6 months of age, (2) at least 8 animals of 7 to 18 months of age, (3) at least 8 animals of 19 to 30 months of age and (4) at least 8 animals over 30 months of age. Antibodies to Brucella abortus were observed in 8 out of 18 municipalities (44.44%),in 8 out of 72 herds included in this study (11.11%) and in 8 animals out of 2343 samples collected (0.34%). The prevalence of test positive cattle by ecoregion/cattle production regions in the state showed no significant differences of risk among them. Likewise, there was no significant difference of risk among the different age categories studied. It was observed that brucellosis is widely spread across the state albeit with low animal prevalence. These results may be used in the design of a strategy for controlling bovine brucellosis in the State of Paraíba.

Seis municípios foram selecionados aleatoriamente em cada uma das três ecorregiões do Estado: a região do Agreste/Litoral (1), a região do Cariri/Curimatau (2) e a região do Sertão (3). Estes 18 municípios foram divididos em quadrantes e uma propriedade foi selecionada em cada quadrante. Foram amostradas propriedades com mais de 50 animais, o que exclui as pequenas propriedades de subsistência. Pelo menos 32 animais foram amostrados de cada rebanho, estratificados nas quatro faixas etárias seguintes: (1) no mínimo 8 animais até 6 meses de idade, (2) no mínimo 8 animais com 7 a 18 meses de idade, (3) no mínimo 8 animais com 19 a 30 meses de idade e (4) no mínimo 8 animais com mais de 30 meses de idade. Anticorpos anti-B. abortus foram observados em 8 de 18 municípios (44,44%), em 8 de 72 rebanhos (11,11%) e em 8 animais dos 2343 amostrados (0,34%). A análise dos resultados de prevalência por ecorregião do Estado não revelou diferença significativa de risco entre elas. A análise dos resultados por categorias de faixa etária também não evidenciaram diferença significativa de risco entre as mesmas. Foi observado que a brucelose está amplamente disseminada no estado embora com uma baixa prevalência animal. Estes resultados podem ser úteis no delineamento de estratégias de controle da brucelose bovina no estado da Paraíba.Universidade de São Paulo.
