RESUMO Uma cabra da raça Saanem, com 3 anos, foi atendida no Hospital Veterinário da Faculdade de Medicina Veterinária e Zootecnia da Universidade de São Paulo, com histórico de emagrecimento progressivo, com doença respiratória não responsiva a antibioticoterapia convencional. O animal apresentava perda de peso, aumento de linfonodo submandibular esquerdo e sintomas de broncopneumonia. Tendo sido considerado positivo no teste cervical comparativo foi sacrificado e à necropsia foram observadas lesões sugestivas de tuberculose nos linfonodos submandibulares e mesentéricos, pulmão e baço. Nos exames laboratoriais houve crescimento, aos 32 dias, de bacilos álcool-ácido resistentes (BAAR), no meio de cultura de Stonebrink, e a estirpe isolada foi identificada no PCR como sendo Mycobacterium bovis. A pesquisa de Corynebacterium sp. foi negativa. Na histopatologia, as lesões examinadas apresentavam características dos granulomas típicos. Usandose coloração para BAAR foi possível observação de bacilos no centro de um granuloma, sugestivo de Mycobacterium spp. Casos de tuberculose em caprinos têm sido considerados raros no Brasil.

ABSTRACT A 3-year-old Saanen-breed was examined at the Veterinary Hospital of the College of Veterinary Medicine and Animal Husbandry of the University of São Paulo, with a history of progressive emaciation and respiratory disease which did not respond to conventional antibiotic therapy. The animal was underweight, had swelling of the left submandibular lymph node and signs of bronchopneumonia. As it was reactor for comparative cervical test, the goat was slaughtered and at necropsy tuberculosis-like lesions were found in its submandibular and mesenteric lymph nodes, lungs and spleen. Acid-fast bacilli growth occurred within 32 days in Stonebrink media culture and the isolate was identified by PCR as M.bovis. Diagnostic test for Corynebacterium sp. was negative. Histopathologic examination showed characteristics of tuberculosis granulomas. When the acid-fast stain was employed in lesions smears, it was possible to observe bacilli in the middle of a granuloma, suggesting Mycobacterium spp. Tuberculosis cases in goats have been considered rare in Brazil.

RESUMO O trabalho foi realizado com o objetivo de analisar leite cru comercializado clandestinamente no Município de Mossoró, RN, quanto à presença de resíduo de beta-lactâmicos. Foi utilizado o teste de triagem Delvotest SP. Durante dois meses, foram coletadas amostras de leite cru comercializado em diferentes pontos de Mossoró; as coletas foram semanais, levando a um total de 32 amostras analisadas. Antes de aplicar o teste, as amostras foram preparadas para inativar possíveis inibidores inespecíficos (lisoenzima, lactoferrina etc), em seguida os testes foram realizados de acordo com as recomendações do fabricante. Todas as amostras analisadas foram negativas. Portanto, as amostras estavam livres de antibióticos ou não continham quantidade maior que o limite máximo resíduo (LMR) permitido no leite. A ausência de amostras positivas do leite cru analisado não permite afirmarmos que a população está livre do problema, pois sabese que este alimento não passa por fiscalização e, dessa forma, pode ser responsável por expor ao risco a saúde das pessoas que o consomem.

ABSTRACT The research was carried out with the objective of analyzing raw milk marketed secretly in the Municipal district of Mossoró, State of Rio Grande do Norte, Brazil, in regard to the presence of beta-lactam residues. Delvotest SP was used as the selection test. For two months, samples of raw marketed milk were collected in different points of Mossoró, the collections were weekly, resulting in a total of 32 analyzed samples. Before applying the test, the samples were prepared to inactivate possible unspecific inhibitions (lisoenzime, lactoferrina, etc.), and soon afterwards the tests were conducted according to the manufacturer’s recommendations. All of the analyzed samples were negative. Therefore the samples were free from antibiotics or they contained amounts less than the maximum residue limit (LMR) allowed in the milk. The absence of positive samples among the raw milk analyzed does not prove that the population is free of the problem, because it is known that this food is not subjected to any control and therefore poses a health risk to those who consume it.
