ABSTRACT

No período de janeiro a outubro de 2007, foram tuberculinizadas 1.866 fêmeas caprinas de diferentes raças e idades distribuídas em 84 propriedades da microrregião de Monteiro, semiárido da Paraíba. Nove cabras (0,48%) foram positivas, duas delas foram sacrificadas e, à necropsia foram observadas lesões sugestivas de tuberculose nos pulmões e no fígado. No exame histopatológico, foram evidenciados granulomas típicos. Foi procedido o cultivo e isolamento de micobactérias, sendo observado o crescimento do agente no meio de cultura de Stonebrink a partir de 36 dias de incubação, com um tempo médio de crescimento de 42 dias. Também foram encontrados resultados positivos na pesquisa de bacilos álcool-ácido resistentes (BAAR) pela coloração de Ziehl-Neelsen. O cultivo de Corynebacterium pseudotuberculosis foi negativo. O presente relato, com isolamento e visualização do agente, bem como verificação de lesões macro e microscópicas, é o primeiro caso de tuberculose confirmado em caprinos do semiárido brasileiro.


From January to October 2007, 1,866 female goats of different breeds and ages from 84 herds of the Monteiro microregion, in a semiarid area of Paraíba State, Brazil, were tuberculinized. Nine goats (0.48%) were positive and two of them were slaughtered, and at necropsy tuberculosis-like lesions were found in lungs and liver. At the histopathologic examination, typical tuberculosis granulomas were observed. Micobacteria culture and isolation were carried out, and there was growth of the agent on the Stonebrink medium culture from 36 days of inoculation with an average growth time of 42 days. Positive results were also found in the research of acid-fast bacilli by Ziehl-Neelsen staining. The culture of Corynebacterium pseudotuberculosis was negative. This report, with isolation and visualization of the agent, as well as verification of gross and microscopic lesions, is the first confirmed case of tuberculosis in goats of a semiarid region of Brazil.
