Estudo epidemiológico tipo caso-controle realizado em Uberlândia, Minas Gerais (MG), Brasil, pesquisou a ocorrência de brucelose em bovinos com bursite cervical, abatidos no período de agosto de 1993 a julho de 1994. O diagnóstico sorológico de brucelose foi realizado mediante a prova de soroaglutinação rápida em placa. Os casos de bursite foram identificados por técnico do Serviço de Inspeção Federal (SIF), com base em características morfológicas, previamente padronizadas. Para a determinação da "Razão de Odds" e do risco atribuível entre bursite e brucelose, utilizaram-se 30 animais com o quadro e, como controle, 90 bovinos sem a patologia. Dos animais com bursite, 13,3% eram brucélicos, contra 5,6% do grupo controle (P=0,115). Dentre aqueles com brucelose e bursite, as bolsas continham fibrina (40,0%) e projeções digitiformes (33,3%); apenas nas bursites dos sorologicamente negativos encontraram-se presença de pus, de nódulos e de líquido viscoso. A "Razão de Odds" encontrada entre brucelose e bursite foi da ordem de 2,61, não sendo demonstrado associação entre bursite cervical e sorologia positiva para brucelose (P>0,05). No âmbito da Saúde Pública e ocupacional, sugere-se a atenção de técnicos e profissionais, visando diminuir o risco de infecção e evitar contaminação de carcaças, equipamentos e instalações. Epidemiological study case-control type carried out in Triângulo abattoir in the city of Uberlândia in the State of Minas Gerais, Brazil, has identified the ocorrence of brucelosis in bovine with supraspinous bursitis, slaughtered from August, 1993 to July, 1994. To diagnose brucelosis "Rapid Agglutination" test was performed on plate with the padronizated antigen count considered positive over 100. The bursas examined were identified by technicians of the Federal Inspection Service based on the presence of ten standardized morphological characteristics. Using the case-control design, 30 animals identified as having supraspinous bursitis were compared with 90 animals randomly selected, without bursitis- but with other characteristics (sex, background, lot, conformation) similar to those affected. All animals were, then, tested for brucelosis. Within the animals with bursitis, 13.33% were found to have brucelosis against 5.56% in the control group (P=0.115). The presence of pus, nodules and viscous fluid was found only among animals who tested negative for brucelosis. The odds ratio found between brucelosis and supraspinous bursitis was 2.61 (P>0.05). As a conclusion it’s suggested attention of technicians and profesionals employed in slaughter houses aiming to reduce the risk of human infection, as well as of carcasses, equipment and installations contamination
