E-mail: marcoskanashiro@ adapar.pr.gov.br We conducted a study using data from fieldwork conducted by autonomous veterinarians to characterize the epidemiological situation of bovine brucellosis in Nossa Senhora Aparecida Settlement, Municipality of Mariluz, State of Parana. Autonomous Veterinarians enabled by the Ministry of Agriculture, Livestock and Supply for tests for brucellosis and tuberculosis were hired by milk producers of the Settlement in order to fulfill a requirement of dairy as a criterion to continue marketing the milk they produce. The requirement was to carry out the examination of brucellosis and tuberculosis in cattle all for the purpose of reproduction present on the property. Were sampled properties of milk and, thus, were examined all the cows over 24 months and bulls for the purpose of reproduction, from which was obtained a blood sample from each animal. In total, 1264 animals were sampled, from 141 properties. Among the properties sampled, an epidemiological questionnaire was applied to check the type of farming and the husbandry and sanitary practices that could be associated with the risk of infection and, moreover, was conducted georeferencing of properties sampled and sanitary orientation in relation to brucellosis. The flock was considered positive if at least one animal was positive on two serological tests (Tube agglutination - TAT and 2-mercaptoethanol - 2-Me). In a simple analysis it was found that the prevalence of outbreaks and infected animals were, respectively, 16.31% and 2.6%. Among the producers questioned, 90% said they buy animals for reproduction, and among them, 57% do not conduct examinations of brucellosis in animals purchased. 18% rent pasture.
