is the most prevalent piroplasm infecting cattle across Egypt. Theileriosis is transmitted by ixodid ticks of the genus . This study aimed to estimate the prevalence of theileriosis in cattle and their associated risk factors for infection.
A total of 570 blood samples were collected from cattle from five governorates (administrative districts) in Egypt and examined using a polymerase chain reaction assay to estimate the prevalence of tropical theileriosis and assess the associated risk factors.
The overall prevalence rate was 16.49%, with the Alexandria district having the highest prevalence. The results revealed that the risk of theileriosis was elevated in older cattle (odds ratio [OR]=8.9, 95% confidence interval [CI]: 3.6-21.9), especially in summers (OR=3.07, 95% CI: 1.4-6.3). Cattle heavily infested with ticks were at particular risk (OR=3.05, 95% CI: 2.1-4.5), as were those to which acaricide had not been applied (OR=13.7, 95% CI: 5.6-33.6).
Understanding the risk factors associated with infection and regular infection monitoring could reduce infection rates and economic losses and is essential for the implementation of efficient control programs.
是埃及感染牛的最普遍的梨形虫。泰勒虫病由属的硬蜱传播。本研究旨在估计牛泰勒虫病的流行率及其相关感染风险因素。
从埃及五个省份（行政区）的牛身上采集了总共570份血样，并使用聚合酶链反应检测法进行检测，以估计热带泰勒虫病的流行率并评估相关风险因素。
总体流行率为16.49%，其中亚历山大地区的流行率最高。结果显示，年龄较大的牛感染泰勒虫病的风险升高（优势比[OR]=8.9，95%置信区间[CI]：3.6 - 21.9），尤其是在夏季（OR=3.07，95%CI：1.4 - 6.3）。蜱虫大量寄生的牛面临特别的风险（OR=3.05，95%CI：2.1 - 4.5），未使用杀螨剂的牛也是如此（OR=13.7，95%CI：5.6 - 33.6）。
了解与感染相关的风险因素并定期进行感染监测可以降低感染率和经济损失，对于实施有效的防控计划至关重要。
