ABSTRACT.- Jardim G.C., Pires P.P., Mathias L.A. & Ribeiro O.C. & Kuchembuck M.R.G. 2006. [Serological diagnosis of bovine brucellosis in adult herd vaccinated with Brucella abortus strain 19 reduced dose.] Diagnóstico sorológico da brucelose bovina em animais adultos vacinados com dose reduzida da cepa 19 de Brucella abortus. Pesquisa Veterinária Brasileira 26(3):177-182. Departamento de Medicina Veterinária, Universidade para o Desenvolvimento do Estado e Região do Pantanal (Uniderp), Rua Alexandre Herculano 1400, Parque dos Poderes, Campo Grande, MS 79037-280, Brazil. E-mail: gustavoj@mail.uniderp.br The study evaluated the use of a reduced dose of the Brucella abortus strain 19 vaccine, in an adult herd negative for the disease, by serological diagnostic techniques, advocated by the Brazilian Program for Animal Brucellosis and Tuberculosis Control and Eradication, and by an indirect ELISA. The complement fixation test detecteed 46.77% positives, the rose bengal test 67.74%, the mercaptoethanol with standard agglutination test 87.09% and the ELISA ID 100%. The reduced dose influenced the serological diagnosis. None of the techniques reached a suitable specificity for use in the herd under those conditions, up to 3 months after vaccination.
