Ocorrência e caracterização da tuberculose em caprinos leiteiros criados no estado de Pernambuco

For a long time, it was believed that the goat species is resistant to infection by Mycobacterium bovis; however, this hypothesis changed when reports of the disease became apparent in various countries. Nevertheless, certain characteristics of tuberculosis in goats and its impact on public health are still unknown. The objective of this study was to describe nosologic, radiologic, anatomo-histopathological, bacilloscopic and biomolecular aspects of tuberculosis in dairy goats with respiratory disease naturally infected, from the state of Pernambuco, Brazil. When we tuberculinized 442 goats with respiratory symptoms, 3.4% (15/442) of these were considered positive in the test. From the positive goats, seven were monitored clinically for 12 months. The etiological agent was identified through the polymerase chain reaction, by amplification of genomic sequences of the Mycobacterium tuberculosis complex and later Mycobacterium bovis. This is the first molecular diagnosis which characterizes the involvement of Mycobacterium bovis in goat tuberculosis in Brazil.

Aspectos clínicos e radiográficos de caprino com megaesôfago

A seven month old female goat showed neck swelling, apathy, appetite and weight loss, restlessness, increased salivation, cough, and regurgitation episodes which occurred post feeding. The animal was evaluated through both clinical and radiographic examinations. Plain radiography was performed and contrasted X-ray was done using barium sulfate. For radiological examination, the lateral projection was used for analysis. The results showed a radiopaque content in the esophageal lumen dorsally positioned to heart with density and appearance similar to the rumen. A dilation of the esophagus was reported and a diagnosis of megaesophagus was made. In conclusion, contrast esophagography must be included in the diagnosis of megaesophagus in goats.
