(1) Background: Anaplasmosis is an infectious disease in camels caused by an obligate intracellular bacterium that is transmitted by ticks. (2) Methods: A cross-sectional study was conducted during 2020 to study the seroprevalence of spp. among in three governorates in Egypt and assess the associated risk factors. Serum samples from 365 camels were examined by a competitive enzyme-linked immunosorbent assay (cELISA) test. (3) Results: Overall, the seroprevalence of anaplasmosis among camels was 18.6%. Multivariable logistic regression was performed, and it was discovered that tick infestation, application of acaricides, grooming practice and body condition were potential risk factors for spp. infection (odds ratio > 1) in dromedary camels. In contrast, the locality in which the camels lived and their age were not significant effects with regard to the occurrence of anaplasmosis. (4) Conclusions: The current findings suggest that improvement of protective measures to limit the effects of the identified risk factors can help to reduce the spread of anaplasmosis among camels in Egypt.
(1) 背景：无形体病是骆驼的一种传染病，由一种专性细胞内细菌引起，通过蜱传播。(2) 方法：2020年开展了一项横断面研究，以研究埃及三个省份的骆驼中无形体属的血清流行率，并评估相关风险因素。通过竞争酶联免疫吸附测定（cELISA）试验检测了365头骆驼的血清样本。(3) 结果：总体而言，骆驼中无形体病的血清流行率为18.6%。进行了多变量逻辑回归分析，发现蜱虫感染、使用杀螨剂、梳理习惯和身体状况是单峰骆驼感染无形体属的潜在风险因素（比值比>1）。相比之下，骆驼生活的地点及其年龄对无形体病的发生没有显著影响。(4) 结论：目前的研究结果表明，改进保护措施以限制已确定风险因素的影响有助于减少埃及骆驼中无形体病的传播。
