RESUMO

The brucellosis is a cosmopolitan anthropozoonosis of economical and in public healthy importance, having the man as accidental host in the epidemiological chain. Front to the exposed, the objective of this research was to study the epidemiological aspects related to Brucella abortus infection in bovine and human, aiming the characterization of the zoonotic character of bovine brucellosis in Correntes town, micro region of Garanhuns, Pernambuco State. A total of 1.145 serum samples were examined to search for antibody anti-Brucella abortus, being 1.089 bovines and 56 human, that resulted in 1.437 serum determinations performed. Samples of both specie were examined by the tamponated acidified antigen (TAA), being the bovine serum positive (74) submitted to the 2-mercaptoetanol (2-ME), and the humans (56) submitted to the standard tube - agglutination (STA) and to the 2-ME. In the cases of reaction to the STA and/or 2-ME, for any title, the human samples were examined by the complement fixation test (CF). With the objective to characterize the risk factors associated to the infection in bovine and among the bovine and human specie, were carried out a questionnaire in each property. To the TAA the serum prevalence was (74/1.089) for bovine and 1.8% (1/56) for human. To the STA was observed positivity in 21.4% (12/56) of the human samples, having no, however, reagent samples to the 2-ME (0% - 0/12). Human samples reagent to TAA (1) or to STA (12) showed negativity to the FC (0% - 0/12). From the 28 studied herds, 18 showed at least one positive animal, determining a prevalence of focus of 64.3% (18/28). Among the analyzed risk factors, the properties that performed the manual milking and had flow of animals exhibited significant association to the brucellosis (p>0,05), contrary to those that practiced mechanical milking and did not sell animals. The bovine brucellosis, despite the official efforts, is characterized as a risk factor to human infection in the town of Correntes, State of Pernambuco, Brazil.
