Small ruminants and camels are important livestock species in the United Arab Emirates (UAE), although infection can limit their productivity. This study aimed to investigate the seroprevalence of infection and its associated risk factors in small ruminants and camels in the Emirate of Abu Dhabi. Additionally, seropositive animals were tested for the DNA of . Multispecies competitive enzyme-linked immunosorbent assay (c-ELISA) and multispecies indirect (i-ELISA) were used to test 3,086 animals from 2022 to 2023. cell surface 31 kDa protein (bcsp31) gene-based real-time polymerase chain reaction (q-PCR) was used to detect DNA. Multivariate logistic regression was used to assess the association between seroprevalence and potential risk factors. The overall seroprevalences of infection were 1.7% (95% confidence interval [CI], 1.2%-2.2%) and 5.8% (95% CI, 5.0%-6.7%) based on serial and parallel testing, respectively. The DNA of was detected in 13 of the 51 seropositive animals. The overall seroprevalence of infection was associated with the region, type of animal holding, species, and age of the animals. In conclusion, this study documented infection in small ruminants and camels in the Emirate of Abu Dhabi, warranting necessary intervention strategies to eliminate infections in livestock populations.
小型反刍动物和骆驼是阿拉伯联合酋长国（阿联酋）重要的家畜品种，尽管感染会限制它们的生产力。本研究旨在调查阿布扎比酋长国小型反刍动物和骆驼中感染的血清流行率及其相关风险因素。此外，对血清阳性动物进行了的DNA检测。采用多物种竞争酶联免疫吸附测定（c-ELISA）和多物种间接酶联免疫吸附测定（i-ELISA）对2022年至2023年的3086只动物进行检测。基于细胞表面31 kDa蛋白（bcsp31）基因的实时聚合酶链反应（q-PCR）用于检测的DNA。采用多变量逻辑回归评估血清流行率与潜在风险因素之间的关联。基于系列检测和平行检测，感染的总体血清流行率分别为1.7%（95%置信区间[CI]，1.2%-2.2%）和5.8%（95%CI，5.0%-6.7%）。在51只血清阳性动物中的13只检测到了的DNA。感染的总体血清流行率与地区、动物饲养类型、物种和动物年龄有关。总之，本研究记录了阿布扎比酋长国小型反刍动物和骆驼中的感染情况，有必要采取干预策略以消除家畜群体中的感染。
