美國科學家發(fā)現(xiàn)豬身上存在能引起類似小兒麻痹癥癥狀的病毒


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(yī)學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(yī)診斷與動物醫(yī)藥創(chuàng)造學的助理教授Paulo Arruda領(lǐng)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(diào)查 。Arruda說:“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(fā)明的薩佩羅病毒不一樣 ?!?br />
