Bovine brucellosis is an infectious bacterial disease caused by members of genus Brucella, affecting both animals and humans, and resulting in a serious economic loss in animal production sector and deterioration of public health. A cross-sectional study was conducted from November 2014 to April 2015 to determine the seroprevalence and associated risk factors of bovine brucellosis in Sendafa, Oromia Special Zone, Ethiopia. A total of 503 blood samples were collected using a simple random sampling technique from dairy cattle of above 6 months of age with no history of previous vaccination against brucellosis. All sera samples were subjected to both Rose Bengal Plate Test for screening and Complement Fixation Test for confirmation. Accordingly, the overall seroprevalence of bovine brucellosis in the study area was 0.40%. The result showed that the seroprevalence of bovine brucellosis in the study area was not statistically significant with all proposed risk factors. No reactors were observed in male animals. The seroprevalence was observed in animals without previous history of abortion. Moreover, information was gathered on individual animal and farm-level risk factors and other farm characteristics using a questionnaire. Awareness among society was poor, so the positive animals can be a potential hazard to animals and humans in the study area. Therefore, public education should be done to improve the awareness of the community on bovine brucellosis and its public health impact with due consideration on the safe consumption of food of animal origin.
牛布鲁氏菌病是一种由布鲁氏菌属成员引起的传染性细菌性疾病，影响动物和人类，导致动物生产部门遭受严重的经济损失，并恶化公共卫生。本研究于 2014 年 11 月至 2015 年 4 月在埃塞俄比亚奥罗米亚特别行政区的森达法进行了一项横断面研究，以确定牛布鲁氏菌病的血清流行率和相关危险因素。采用简单随机抽样技术，从无布鲁氏菌病既往疫苗接种史的 6 月龄以上奶牛中采集了 503 份血液样本。所有血清样本均进行虎红平板试验（Rose Bengal Plate Test）筛查和补体结合试验（Complement Fixation Test）确认。结果显示，研究区牛布鲁氏菌病的总血清流行率为 0.40%。结果表明，研究区牛布鲁氏菌病的血清流行率与所有提出的危险因素均无统计学意义。未在雄性动物中观察到反应原。在无流产既往史的动物中观察到血清流行率。此外，还使用问卷收集了个体动物和农场层面的危险因素以及其他农场特征的信息。社会意识薄弱，因此，阳性动物可能对研究区的动物和人类构成潜在威胁。因此，应开展公众教育，提高社区对牛布鲁氏菌病及其对公共卫生影响的认识，并适当考虑动物源性食品的安全消费。
