Abstract

Bovine tuberculosis is an illness which has indirect influence on economy, as well as public health. Many animals infected by the agent that causes the sickness are slaughtered very often, and it becomes a worrying situation, once the diagnostic of tuberculosis at slaughter- house is primary restricted to macroscopic diagnostic of the suspected lesions, which can lead to a wrong diagnostic. So, the veterinary is put in a difficult situation in the identification of lesions in the slaughter- room. Forty two samples of carcasses that were removed for DIF (Department of Finally Inspection) were collected in a slaughter- house of Uberlândia due to suspicion of tuberculosis. They were analyses and diagnosticated by the histopathology so that the sickness could be confirmed. The samples were put in formaldehyde 10% and led to Department de Histopathology UFU for technical procedus in the preparation of slides. The results showed that 69, 04% of the samples really confirmed tuberculosis and 30, 95% were classified as inespecific linfadenites. The characteristics age, race and sex were evaluated statically significative dependence the characteristic sex, and independence between the characteristics age and sex, all of them analyses in relation to the classification of tuberculosis in typical or atypical. All the samples belonged to female animals which come from Triângulo Mineiro e Alto Paranaiba.
