　　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.

　　愛(ài)荷華州立大學(xué)的一名獸醫(yī)學(xué)研究人員在仔豬中樞神經(jīng)組織發(fā)明了一種新型病毒，它類如小兒麻痹癥，會(huì)使仔豬后腿軟弱無(wú)力。由于仔豬后腿上乏力的未解之謎，導(dǎo)致11周大的豬不能行走，獸醫(yī)診斷與動(dòng)物醫(yī)藥創(chuàng)造學(xué)的助理教授Paulo Arruda領(lǐng)導(dǎo)了一支來(lái)自愛(ài)荷華州立大學(xué)、明尼蘇達(dá)大學(xué)和堪薩斯州立大學(xué)的診斷能手組，對(duì)有這些癥狀的仔豬抽樣調(diào)查。Arruda說(shuō)：“能手組發(fā)明豬的中樞神經(jīng)組織存在微觀病變，含有一種研究人員從未遇到過(guò)的新型薩佩羅病毒。薩佩羅病毒從屬于豬的常見(jiàn)病毒組，但這種特別的病毒菌株卻與其他先前發(fā)明的薩佩羅病毒不一樣?！?/p>
