美國科學家發現豬身上存在能引起類似小兒麻痹癥癥狀的病毒

病毒


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.

愛荷華州立大學的一名獸醫學研究人員在仔豬中樞神經組織發明了一種新型病毒，它類如小兒麻痹癥，會使仔豬后腿軟弱無力 。由于仔豬后腿上乏力的未解之謎，導致11周大的豬不能行走，獸醫診斷與動物醫藥創造學的助理教授Paulo Arruda領導了一支來自愛荷華州立大學、明尼蘇達大學和堪薩斯州立大學的診斷能手組，對有這些癥狀的仔豬抽樣調查 。Arruda說：“能手組發明豬的中樞神經組織存在微觀病變 ， 含有一種研究人員從未遇到過的新型薩佩羅病毒 。薩佩羅病毒從屬于豬的常見病毒組，但這種特別的病毒菌株卻與其他先前發明的薩佩羅病毒不一樣 ?！?br />
