【 摘 要 】

The aim of this study was to determine the frequency of positive herds (foci) and positive animals for bovine tuberculosis in the state of Paraíba, Northeast region of Brazil. Data from the Agency of Agricultural Protection in the state, collected from its 23 microregions, during the January 2008 to July 2009 period, were used. During this period, 10,963 herds were examined and 54,472 cattle were submitted to the tuberculin test. For diagnosis the cervical and caudal-fold tuberculin tests were used as screening tests in dairy and beef cattle, respectively; as confirmatory test, comparative cervical test was used. A herd was considered focus when presented at least one positive animal. Of the herds investigated, 62 (0.57%) had at least one positive animal, and of the animals examined, 136 (0.25%) were positive. There was significant difference (p<0.001) in the proportion of positivity for females (0.32%) and males (0.04%). Despite low frequency of foci of brucellosis and seropositive animals, it is necessary to conduct measures including awareness of producers, surveillance in sanitary barriers and periodic surveys of epidemiological situation of this disease especially in the regions with highest frequency of infection, aiming to avoid, or at least minimize, the spread of the agent.
