Bovine tuberculosis, caused by , is a chronic zoonotic disease that persists in Ethiopia despite global control efforts, impacting public health and the economy. However, little is known about the epidemiology of bovine tuberculosis in Southwest Ethiopia. This study aims to assess the prevalence of bovine tuberculosis and identify associated risk factors in dairy cattle. A cross-sectional study was conducted from October 2022 to October 2023 in four districts in the Sheka, Bench-Sheko, and Keffa zones. A multistage sampling approach was employed, resulting in the selection of 1,152 cattle from various herds. Tuberculin skin testing was performed to detect bovine tuberculosis, and data on potential risk factors were collected through questionnaires. Logistic regression models were used to analyze the association between bovine tuberculosis and various risk factors. The overall prevalence of bovine tuberculosis was 4.95% at the cow level and 22.19% at the herd level in the study areas. Significant herd-level risk factors for bovine tuberculosis included lowland areas, larger herd sizes, and the introducing new animals. At the cow level, risk factors included age, breed, body condition, herd size, introduction of new animals, and management system. The study reveals a high prevalence of bovine tuberculosis in dairy cattle in Southwest Ethiopia, identifying key risk factors. Effective control requires targeted interventions, such as improved management practices, enhanced farmer awareness, and a better understanding of and guidance on bovine tuberculosis strategies in Ethiopia. Future research should isolate and characterize in the study areas.
牛结核病由[病原体名称未给出]引起，是一种慢性人畜共患病，尽管全球都在努力防控，但在埃塞俄比亚仍持续存在，影响着公共卫生和经济。然而，埃塞俄比亚西南部牛结核病的流行病学情况鲜为人知。本研究旨在评估奶牛中牛结核病的患病率，并确定相关风险因素。2022年10月至2023年10月在谢卡、本奇-谢科和凯法地区的四个区开展了一项横断面研究。采用多阶段抽样方法，从不同牛群中选取了1152头牛。进行结核菌素皮肤试验以检测牛结核病，并通过问卷调查收集潜在风险因素的数据。使用逻辑回归模型分析牛结核病与各种风险因素之间的关联。在研究区域，牛结核病在个体奶牛层面的总体患病率为4.95%，在牛群层面为22.19%。牛结核病在牛群层面的显著风险因素包括低地地区、牛群规模较大以及引入新动物。在个体奶牛层面，风险因素包括年龄、品种、身体状况、牛群规模、引入新动物和管理制度。该研究揭示了埃塞俄比亚西南部奶牛中牛结核病的高患病率，并确定了关键风险因素。有效的防控需要有针对性的干预措施，如改进管理做法、提高农民意识以及更好地了解和指导埃塞俄比亚的牛结核病防控策略。未来的研究应在研究区域分离并鉴定[病原体名称未给出]。
