摘　　要：马病毒性动脉炎(EVA)是一种由马动脉炎病毒(EAV)引起马属动物主要通过呼吸系统和生殖系统传播的传染病,是危害养马业及赛马业的重要疾病之一。本试验应用纯化EAV全病毒为抗原建立EAV-IgG间接ELISA方法与西班牙INGEZIM-ARTERITIS试剂盒分别检测华南、华中、东北和西北地区共计383份马血清样品。其结果为:华南地区赛马动脉炎阳性率为26%,华中地区赛马动脉炎阳性率为0,东北地区役用马动脉炎阳性率为8.26%,西北地区役用马动脉炎阳性率为7.55%。鉴于此,有必要加强EVA检测,掌握EVA在我国分布,以有效的预防和控制本病传播。Equine viral arteritis （EVA） , caused by equine arteritis virus （EAV） , is a highly contagious respiratory and reproductive viral disease of equids, can have a significant economic effect on both breeding and performance sectors of the horse industry. To understand the serological prevalence of equine arteritis virus （EAV） infection among the horses from Southern, Central, Northeastern and Northwestern China in 2009, an EAV-antigen indirect enzyme-linked immunosorbent assay （ELISA） was utilized to examine 383 horse serum samples collected from the racehorses and draft horses randomly selected from the above four administrative regions in this study. Data showed that a total seropositive rate of EAV antibodies was 26% in Southern China and 0% among the race horses in Central China. And the seropositive rate of EAV antibodies among the draft horses in Northeastern and Northwestern China were 7.55% and 8.26% separately. Therefore, it is important to strengthen EVA surveillance and understand its distribution in the country in order to prevent and control its occurrence and spreading.
