摘要

背景:布鲁氏菌病是一种传染性的、经济意义重大的细菌性疾病,影响全世界的动物,是世界上最被忽视的人畜共患疾病之一。这种疾病对动物和动物产品的贸易构成障碍,对公众健康构成危害,并阻碍动物的自由流动。方法:2019年12月至2020年5月,在埃塞俄比亚中部高地进行了一项横断面研究,以确定近期流产病例的奶牛布鲁氏菌病的血清患病率并确定潜在危险因素。在有关的农场和农场进行了有目的的抽样,以筛查奶牛中最近的流产病例。为进行血清学检测,采集了352头奶牛血液样本。采用玫瑰孟加拉板试验对血清样品进行初步筛选,补体固定试验作为确认试验。结果:采用RBPT和CFT联合检测,牛布鲁氏菌病的总血清阳性率为0.6% (95% CI: 0.16-2.09)。胎膜保留(OR = 32.74, p = 0.006)、市场替代(OR = 16.55, p = 0.002)、繁殖方式(OR = 7.58, p = 0.027)、流产后期(OR = 14.74, p = 0.0002)均为显著相关的危险因素。结论:目前的血清学研究表明,布鲁氏菌病在研究地区的奶牛中流行率较低。然而,由于没有采取控制措施,在研究地点的奶牛和暴露人群中可能存在布鲁氏菌病传播的风险。由于政府所有和小型农场的牛布鲁氏菌病发病率较低,建议实施一种对农民进行补偿的检测和屠宰方法。

Seroprevalence of Bovine Brucellosis in Selected Sites of Central Highland of Ethiopia.

Background: Brucellosis is a contagious, economically significant bacterial disease that affects animals worldwide and is one of the most neglected zoonotic diseases in the world. The disease poses a barrier to the trade of animals and animal products, represents a public health hazard, and is an impediment to free animal movement.

Methods: A cross-sectional study was carried out from December 2019 to May 2020 in order to determine seroprevalence and identify potential risk factors for brucellosis in dairy cows in the Central Highlands of Ethiopia with recent cases of abortion. Purposive sampling was carried out on the farms and kebeles in question to screen for recent cases of abortion in dairy cows. For the purpose of performing serological testing, 352 blood samples from dairy cattle were obtained. The Rose Bengal Plate test was used to initially screen the serum samples, and the Complement Fixation test was utilized as a confirmatory test.

Results: Using combined RBPT and CFT tests, the overall seroprevalence of bovine brucellosis was 0.6% (95% CI: 0.16-2.09). Retained fetal membrane (OR = 32.74, p = 0.006), market-based stock replacement (OR = 16.55, p = 0.002), breeding method (OR = 7.58, p = 0.027), and late stage of abortion (OR = 14.74, p = 0.0002) are all significantly associated risk factors.

Conclusion: The present seroprevalence study revealed that brucellosis is prevalent at a lower rate among dairy cattle in the study areas. However, there is a possible risk of brucellosis transmission in dairy cattle and the exposed human population in research locations because no control measures were put in place there. Implementing a test and slaughter method with compensation for farmers is advised due to the low prevalence of bovine brucellosis in government-owned and small-holder farms.
