The distribution of antibodies against swine and Hong Kong influenza viruses among hogs in Miyagi Prefecture was examined. Of 456 serum specimens collected since July 1977, 12 were found to be positive against swine influenza virus and 6 against Hong Kong influenza virus. Such serological results reveal that swine and Hong Kong influenza viruses coexist in Japanese hogs and suggest that swine influenza virus reappeared in mid-1977.
对宫城县猪群中抗猪流感病毒和香港流感病毒抗体的分布情况进行了检测。自1977年7月以来采集的456份血清样本中,有12份对猪流感病毒呈阳性反应,6份对香港流感病毒呈阳性反应。这些血清学检测结果表明,猪流感病毒和香港流感病毒在日本猪群中并存,也提示猪流感病毒于1977年年中再次出现。
