To compare seroprevalence of antibodies against equine arteritis virus (EAV) in horses residing in the United States with that of imported horses.
Serologic survey.
Serum samples from 364 horses on 44 equine operations in California and 226 horses imported from various countries.
Serum samples were collected from each imported horse and from up to 20 horses on each operation. For resident horses, the number of sampled horses on each operation was determined on the basis of the number of horses on the operation. Samples were tested for antibodies against EAV by use of a serum neutralization test.
1.9% of resident horses and 18.6% of imported horses were seropositive to EAV, including 16.1% of imported stallions.
Results indicate that the EAV seroprevalence of horses residing in California is considerably lower than that of imported horses, including imported stallions.
比较美国本土马匹与进口马匹中抗马动脉炎病毒(EAV)抗体的血清流行率。
血清学调查。
来自加利福尼亚州44个马场的364匹马以及从各国进口的226匹马的血清样本。
从每匹进口马以及每个马场最多20匹马中采集血清样本。对于本土马匹,每个马场采样马匹数量根据该马场马匹数量确定。样本采用血清中和试验检测抗EAV抗体。
1.9%的本土马匹和18.6%的进口马匹EAV血清学检测呈阳性,其中包括16.1%的进口种公马。
结果表明,加利福尼亚州本土马匹的EAV血清流行率显著低于进口马匹,包括进口种公马。
