ABSTRACT.- Almeida R.F.C., Madruga C.R., Soares C.O., Fernandes M.C., Carvalho N.M., Jorge K.S.G. & Osório A.L.A.R. 2006. [Specific immune response of cattle to experimental sensibilization by inactivated Mycobacterium bovis and Mycobacterium avium.] Resposta imune específica de bovinos experimentalmente sensibilizados com inóculos inativados de Mycobacterium bovis e Mycobacterium avium. Pesquisa Veterinária Brasileira 26(4):195-200. Departamento de Medicina Veterinária da Universidade Federal de Mato Grosso do Sul, Cidade Universitária, Campo Grande, MS 79070-900, Brazil. E-mail: analudmv@nin.ufms.br The presumptive diagnosis of bovine tuberculosis is based on analysis of the immune response to micobacterial antigens. This experimental simulation of sensibilization by Mycobacterium bovis and Mycobacterium avium in cattle aimed to verify the immune response by both the cervical comparative test and the evolution of the specific production of gamma-interferon, and also to identify interference of unspecified reactions by M. avium on the test results. The results support that the experimental animals started a response of delayed hypersensitivity to the inactivated bacilli, and that both diagnostic tests for bovine tuberculosis were efficient for the identification of animals sensitized with M. bovis and for discrimination of reactions generated by inoculation of cattle with M. avium.
