1985 ~ 1988年，用血凝抑制试验（HI）对日本本州岛东北地区60个猪场的2496份猪血清进行了猪血凝性脑脊髓炎病毒（HEV）、人冠状病毒（HCV）和牛冠状病毒（BCV）抗体的检测。抗HEV 67 N株和HCVOC 43株抗体阳性率分别为82.1%和91.4%，抗BCV卡克川株抗体阳性率为44.2%。在所有农场（包括血清阳性率相对较高的农场）中均未发现HEV感染的临床体征。结果表明，HCV或抗原相关病毒以及HEV可能在东北地区的猪中持续存在。
From 1985 to 1988, a total of 2496 swine sera from 60 farms in the Tohoku District of the Honshu Island of Japan were examined for antibodies to swine haemagglutinating encephalomyelitis virus (HEV), human coronavirus (HCV) and bovine coronavirus (BCV) by haemagglutination-inhibition (HI) test. Antibodies to HEV 67N strain and HCV OC43 strain were highly prevalent with positivity rates of 82.1 and 91.4%, respectively, while seropositivity rate to BCV Kakegawa strain was 44.2 %. No clinical signs of HEV infection were noticed in any farms including farms with relatively high seropositivity. The results suggested that HCV or antigenitically related virus(es) as well as HEV might be perpetuated in swine in the Tohoku District.
