Equine coronaviruses (ECoV) are the only coronavirus known to infect horses. So far, data on ECoV infection in horses remain limited to the USA, France and Japan and its geographic distribution is not well understood. We carried out RT-PCR on 306 nasal and 315 rectal swabs and tested 243 sera for antibodies to detect coronavirus infections in apparently healthy horses in Saudi Arabia and Oman. We document evidence of infection with ECoV and HKU23 coronavirus by RT-PCR. There was no conclusive evidence of Middle East respiratory syndrome coronavirus infection in horses. Serological data suggest that lineage A betacoronavirus infections are commonly infecting horses in Saudi Arabia and Oman but antibody cross-reactivities between these viruses do not permit us to use serological data alone to identify which coronaviruses are causing these infections.
马冠状病毒（ECoV）是已知唯一感染马的冠状病毒。迄今为止，关于马感染 ECoV 的数据仅限于美国、法国和日本，其地理分布尚不清楚。我们对沙特阿拉伯和阿曼的 306 份鼻腔和 315 份直肠拭子进行了 RT-PCR 检测，并对 243 份血清进行了冠状病毒抗体检测，以检测无症状马匹的冠状病毒感染情况。我们通过 RT-PCR 检测到 ECoV 和 HKU23 冠状病毒感染的证据。没有确凿的证据表明马感染了中东呼吸综合征冠状病毒。血清学数据表明，A 谱系β冠状病毒感染在沙特阿拉伯和阿曼的马匹中普遍存在，但这些病毒之间的抗体交叉反应性不允许我们仅使用血清学数据来确定哪些冠状病毒引起这些感染。
