Abstract in Portuguese
Foi realizado estudo com o objetivo de conhecer as características da tuberculose bovina em bubalinos e demonstrar a importância da doença nesses animais em termos de saúde pública; através da observação macroscópica, do estudo histopatológico e do isolamento e identificação de cepas micobacterianas foram amostrados carcaças e órgãos de 1735 bubalinos abatidos em Belém, Estado do Pará, determinando-se a prevalência de 7,66%, observando-se 72,1% de casos de alterações localizadas e 27,9% de casos de alterações generalizadas; as alterações localizadas estavam presentes em 60,25% dos casos no aparelho respiratório, em 20,08% dos casos no conjunto cabeça-lingua, em 9,62% dos casos na carcaça, em 6,28% dos casos na cavidade abdominal e em 3,77% dos casos na mama; 15,48% das alterações tuberculosas estavam presentes no parênquima pulmonar. No isolamento de 49 cepas micobacterianas tipificadas, 33 (67,3%) eram deMycobacterium bovis, 2 (4,1%) de M. gordonae, 8 (16,3%) de M. fortuitum, 2 (4,1%) do complexo M. avium e 4 (8,2%) de micobactérias de crescimento rápido escotocromogênico; 55,1% das cepas foram isoladas no aparelho respiratório, com cêrca de um terço delas no parênquima pulmonar; M. avium foi isolado como agente de alteração pulmonar. Concluiu-se que no abate de bubalinos em Belém, as carcaças e os órgãos dos animais apresentavam características anatomopatológicas indistingüíveis daquelas do processo infeccioso da tuberculose bovina. A tuberculose constitui-se em importante doença de bubalinos criados no Estado do Pará, detectada no abate dos animais e apresentando o aparelho respiratório como o mais importante sítio das alterações e a via primária de infecção.

Abstract in English
A study on bovine tuberculosis in water buffaloes slaughtered for consumption in Belém city, Pará state (Brazil) was made to know characteristics of the disease in this specie and demmonstrating public health importance of its; on the basis of macroscopic observation of lesions in organs and carcass from 1.735 slaughtered animais, histologic substrat of the lesions and the identification of mycobacteria samples in the observed alterations, was determined the prevalence rate of 7,66%; 72,1% cases of localized alterations and 27,9%, cases of generalized alterations were observed; the localized alterations were distributed as follows: 60,25% cases on respiratory system (lung and lymph nodes), 20,08% cases on the head, 9,62% cases in the carcass, 6,25% cases in the abdominal cavity and 3,77% cases in the breast; 15,48% tuberculous alterations were localized in the lung parenchyma. 49 samples of mycobacteria were identified from whose 33 (67,3%) were Mycobacteria bovis, 2 (4,1%) M. gordonae, 8 (16,3%) were M. jortuitum, 2 (4,1%) M. avium complex and 4 (8,2%) were rapid growing scotochromogen mycobacteria; 55, 1% of the samples were isolated in the respiratory system, with a third of them in the lung parenchyma; M. avium complex was identified like lung alteration agent too. So it was conclude that organs and carcass from water buffaloes slaughtered in Belém city had anatomopathologic characteristics indistinguisable from those of bovine tuberculosis, this disease is too important to water buffalo breeding in the Pará state, it is currently saw in the slaughter house and has the respiratory via as the route of infection.
