Resumo
O perfil sorológico de 21 fêmeas bubalinas vacinadas entre três a oito meses de idade, com amostra-padrão da vacina B19 (Brucella abortus), foi avaliado pelas provas do antígeno acidificado tamponado corado com rosa bengala (AAT), 2-mercaptoetanol (2-ME) e fixação de complemento (FC). As colheitas foram realizadas no dia zero (vacinação), 15, 30, 45,60 e, subsequentemente, a cada 30 dias até o 720o dia pós-vacinal. Nenhum animal foi reagente no dia zero. No 15o dia pós-vacinal, acima de 95% dos animais reagiram em todas as provas. Os títulos máximos na soroaglutinação lenta em tubos e 2- mercaptoetanol foram obtidos entre 15o e 45o dia após a vacinação. Entre 120 e 150 dias foi observado o declínio das reações nos animais em todas as provas. Na FC, AAT e 2-ME todos os animais resultaram não reagentes, respectivamente, aos 270, 300 e 360 dias da vacinação. Nenhum dos animais apresentou oscilação de títulos ou reações nas três provas após 360 dias de acompanhamento.
The serological profiles of 21 female buffaloes, vaccinatedd at three to eight months of age using the B19 standard strain of Brucella abortus were evaluated by rose bengal plate, 2-mercaptoethanol and complement fixation tests. The serum samples were collected in day zero (vaccination), 15, 30, 45, 60th and, subsequently to each 30 months, until 720th day after vaccination. No animal showed reaction in day zero. In 15th day, more tham 95% of animals showed reaction in all tests. The maximum levels of antibodies detected by the tube agglutination and 2-mercaptoethanol tests were found between the 15 and 45th days after vaccination. Between 120 and 150 days after vaccination was observed decreased of reactions in all the tests. All the animals showed absence of reactions in complement fixation, rose bengal plate and 2- mercaptoethanol tests at 270, 300 and 360 days respectively after vaccination. None of animals presented oscillation of titers on reactions in any test after 360 day of study.
