The bovine tuberculosis (BT) bacteriological diagnostic profile provides important elements for epidemiological investigations about this ilness. With this intention had been tried to characterize the BT bacteriological exams results accomplished at LANAGRO in Pedro Leopoldo, Minas Gerais, Brazil, from 2004 to 2008. To that, a descriptive study was proceeded in order to analyze this group of obtained information, taking into account some present variables in the Guiding Formularies of Samples for Tuberculosis Diagnosis. The information feed a computerized data base system, that was subsequently processed using the frequencies distribution, with the purpose of obtain graphics and tables. It could be verified that the Brazilian state of Minas Gerais had sent 89.3% of the samples to LANAGRO/MG during the period of study. They showed 65.9% (574/871) of positivity for Mycobacterium bovis. Thepresence of suggestive lesions of tuberculosis was 79.4% (692/871), and from these, 80.9%(560/692) attributed to M. bovis. The lesions are concentrated in respiratory treat (53.1%), followed for carcass (20.2%), abdominal cavity (16.5%), head-tongue complex (8.3%) and breast (2.0%). The pulmonary lymphnodes (19.7%), mediastinal (12.8%) and pulmonary parenchyma (12.0%) were the main tissues in which had been detected the BT provoker agent with more regularity. The bovines profiles of sex, race and age that originated samples for the laboratory were composed for females (67.1%) from milk producers races (40.1%) in the age of two years and a half until seven years (85.2%). The slaughter of animals with pathological alterations from tuberculosis occurred in establishments under sanitary inspection (96.2%), withthe total condemnation of carcasses in 77.5% of the times. In properties of slaughtered bovines precedence was informed that did not happen other cases of the disease in 38.8% of the times. However, only 22.2% of the slaughtered bovines possessed historic of some accomplishedtuberculinization. In those positives to tuberculinization, the M. bovis was isolated in 55.8% of the cases. It is considered that the characterization of TB bacteriological diagnosis results, executed in this research work, provides subsidies to actions of epidemiological vigilance against this illness
