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 two years. 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. |
