猪血凝性脑脊髓炎病毒抗体的调查

Serological investigation of antibody against hemagglutinating encephalomyelitis virus in pigs

应用血凝和血凝抑制试验检测了从吉林省部分地区采集的猪血清中血凝性脑脊髓炎病毒(HEV)抗体。结果,212份样品中有94份呈现HEV抗体阳性反应,阳性率高达44.3%。被采集血清的猪未表现临床症状,说明该地区的猪群中存在HEV隐性感染。

The total of 212 swine sera from 6 districts in Jilin Province were examined for antibodies against swine hemagglutinating encephalomyelitis virus（HEV） by hemagglutination inhibition test. The antibodies against HEV were prevalent at positive rates of 44.3%. No clinical sign of HEV infection was noticed in any districts. The results showed that pigs had been infected recessively by HEV in these districts.
