　　US - A veterinary researcher at Iowa State University has discovered a novel virus in the central nervous tissues of young pigs with polio-like weakness in their hind legs.Paulo Arruda, an assistant professor of veterinary diagnostic and production animal medicine, led a team of diagnosticians from Iowa State, the University of Minnesota and Kansas State University in an effort to investigate samples from 11-week-old pigs that couldn’t walk due to a mysterious weakness in their hind legs.The diagnostic team found microscopic lesions in the pigs’ central nervous tissues containing a novel sapelovirus that researchers hadn’t previously encountered. Sapeloviruses belong to a family of viruses commonly found in pigs, but this particular strain was different from all other sapeloviruses previously described, Mr Arruda said.

　　爱荷华州立大学的一名兽医学研究人员在仔猪中枢神经组织发明了一种新型病毒，它类如小儿麻痹症，会使仔猪后腿软弱无力。由于仔猪后腿上乏力的未解之谜，导致11周大的猪不能行走，兽医诊断与动物医药创造学的助理教授Paulo Arruda领导了一支来自爱荷华州立大学、明尼苏达大学和堪萨斯州立大学的诊断能手组，对有这些症状的仔猪抽样调查。Arruda说：“能手组发明猪的中枢神经组织存在微观病变，含有一种研究人员从未遇到过的新型萨佩罗病毒。萨佩罗病毒从属于猪的常见病毒组，但这种特别的病毒菌株却与其他先前发明的萨佩罗病毒不一样。”
