摘要：

摘要： 从辽宁省各地区采集猪血清样本，应用血凝和血凝抑制试验检测血凝性脑脊髓炎病毒(HEV)抗体。结果，910份样品中有451份呈现HEV抗体阳性反应，阳性率为49.6%；抽检了10个规模化养猪场共280份样品，阳性率高达70.0%；抽查了不同年龄阶段猪血清样品，种母猪阳性率最高，为73.8%，仔猪次之，为67.5%，育肥猪最低，为37.0%。调查证明辽宁省各地区普遍存在HEV感染，被采集血清的成年猪未表现临床症状，说明HEV在本地区的猪群中主要表现为隐性感染，仔猪有少数出现症状，诊断为HEV与猪瘟或猪繁殖与呼吸综合征等混合感染。关键词：血凝性脑脊髓炎病毒；血清学调查；猪；

Abstract:

Abstract: The swine serum samples were collected from various regions of Liaoning Province, and the investigation was carried out by the application of hemagglutination and hemagglutination inhibition test for detection of hemagglutinating encephalomyelitis virus (hemagglutinating encephalomyelitis virus, HEV) antibody. As a result, there were 451 samples with HEV positive antibodies in the total 910 samples detected, of which the positive rate reached 49.6%. Among a total of 280 samples selected from 10 large-scale swine farms, the HEV antibodies’ positive rate was as high as 70.0%, and in a sample of different age stages of pig serum samples, the highest HEV antibodies’ positive rate of sows took up 73.8%, 67.5% went to the piglets and the lowest 37.0% finishing swine. Investigating results proved that there existed the prevalence of HEV infection at the regions of Liaoning Province. In addition, adult swine, from which serum was collected, showed no clinical symptoms, which might indicate that the disease mainly expressed in implicit infections, and a small number of piglets showed clinical symptoms. Taken together, the diagnosis result was HEV mixed infection with SFV and /or such as PRRSV. Keywords: HEV; serological investigation ; swine
