ABSTRACT
The aim of this work was to isolate and characterize microorganisms in hypertrophied lymph nodes or gross lesions suggestive of tuberculosis collected from 12 goats and 28 sheep slaughtered at the public slaughterhouse of Patos municipality, Paraíba State, in the Northeast region of Brazil. The identification of mycobacteria was performed by the PRA method (PCR-Restriction Enzyme Analysis). Histopathological examination of lesions was also performed. Organs affected were liver, lung, mammary gland, bladder and mediastinal, mesenteric, submandibular, parotid, popliteal, precrural, prescapular and superficial inguinal lymph nodes. Histopathological examination showed the presence of granulomas in 8 (20.00%) animals. Of the 12 goats, 1 (8.33%) was positive in the culture of mycobacteria, and by PRA method the isolate was classified as belonging to the M. tuberculosis complex. Two (7.14%) sheep were positive for the presence of environmental mycobacteria. There was isolation of Corynebacterium pseudotuberculosis in 8 (66.66%) goats and 17 (60.71%) sheep, and simultaneous isolation of mycobacteria and C. pseudotuberculosis in 1 (8.33%) goat and 1 (3.57%) sheep. The isolation of mycobacteria of the M. tuberculosis complex in goats in this study raises concerns of public health, as professionals involved in handling these animals and the meat and milk consumers are exposed to the risk [...]
RESUMO
O objetivo do presente trabalho foi isolar e tipificar micro-organismos presentes em linfonodos hipertrofiados ou lesões macroscópicas sugestivas de tuberculose colhidos de 12 caprinos e 28 ovinos abatidos no matadouro público do município de Patos, Paraíba. A identificação de micobactérias foi feita com o método PRA (PCR-Restriction Enzyme Analysis). Também foi realizado o exame histopatológico das lesões. Os órgãos afetados foram fígado, pulmão, glândula mamária, bexiga e linfonodos mediastínicos, mesentéricos, submandibulares, parotídeos, poplíteos, pré-crural, pré-escapular e inguinal superficial. O exame histopatológico apontou a presença de granulomas em 8 (20,00%) animais. Dos 12 caprinos, 1 (8,33%) foi positivo no cultivo de micobactérias, e pelo método PRA o isolado foi classificado como pertencente ao complexo M. tuberculosis. Dois (7,14%) ovinos foram positivos para a presença de micobactérias ambientais. Houve isolamento de Corynebacterium pseudotuberculosis em 8 (66,66%) caprinos e em 17 (60,71%) ovinos, e isolamento simultâneo de micobactérias e C. pseudotuberculosis em 1 (8,33%) caprino e 1 (3,57%) ovino. O isolamento de micobactéria do complexo M. tuberculosis em caprinos no presente trabalho levanta preocupações do ponto de vista de saúde pública, uma vez que profissionais envolvidos na manipulação destes animais, bem como a população consumidora de carne [...]
