          Abstract

          Este trabalho teve como objetivo determinar a frequência de rebanhos positivos e de animais soropositivos para leptospirose e brucelose bovina em propriedades rurais de agricultura familiar da mesorregião do Agreste, estado da Paraíba, bem como identificar fatores de risco. Foram colhidas amostras de sangue de 771 animais procedentes de 130 rebanhos em cinco municípios. Para o diagnóstico sorológico da leptospirose, utilizou-se o teste de soroaglutinação microscópica (SAM), com 24 sorovares de Leptospira spp. como antígenos, e para brucelose, o teste do antígeno acidificado tamponado (AAT) como prova de triagem e o teste do 2-mercaptoetanol (2-ME) como prova confirmatória. Para leptospirose, a frequência de propriedades positivas e animais soropositivos foi de 18,4 e 3,6%, respectivamente; para brucelose, 7,7% das propriedades e 1,9% dos animais foram positivos. O sorovar de Leptospira spp. mais frequente foi o Hardjo. A compra de bovinos foi identificada como fator de risco para brucelose bovina (odds ratio = 5,25; p = 0,044). Sugere-se a necessidade de adoção e/ou intensificação de medicas de prevenção e controle com o objetivo de evitar perdas econômicas e transmissão dos agentes aos seres humanos, bem como a compra de animais precedida do conhecimento da sua condição sanitária.

          The aim of this investigation was to determine the frequency of positive herds and seropositive animals to bovine leptospirosis and brucellosis in family farm rural properties from the mesoregion of the State of Paraíba, as well as to identify risk factors. Blood samples were collected from 771 animals from 130 herds in five municipalities. For the serological diagnosis of leptospirosis, the microscopic agglutination test (MAT) using 24 Leptospira spp. serovars as antigens was carried out, and for brucellosis the Rose-Bengal Test (RBT) was used as screening test and the 2-mercaptoethanol test (2-ME) to confirm. For leptospirosis, the frequency of positive herds and seropositive animals was 18.4 and 3.6%, respectively; for brucellosis, 7.7% of the herds and 1.9% of the animals were positive. The most frequent Leptospira spp. serovar was Hardjo. Bovine purchase was identified as a risk factor to bovine brucellosis (odds ratio = 5.25; p = 0.044). The need for adoption and/or intensification of control and prevention measures was suggested in order to avoid economic losses and the transmission of the agents to humans, as well as the purchase of animals with known sanitary conditions.

            Leptospirosis as a cause of reproductive failure.

            W Ellis (1994)
            Leptospirosis is a zoonotic disease caused by members of the genus Leptospira. Veterinarians' perceptions of leptospirosis as a disease of domestic animals has undergone considerable modification in the past decade or so because they have increasingly appreciated the role of the host-maintained leptospires as causes of reproductive wastage in their respective host species kept under modern intensive management systems.
