UK - The wide diversity of flu in pigs across multiple continents, mostly introduced from humans, highlights the significant potential of new swine flu strains emerging, according to a study to be published in eLife.While swine flu viruses have long been considered a risk for human pandemics, and were the source of the 2009 pandemic H1N1 virus, attention has recently turned to the transmission of flu viruses from humans to pigs."Once in pigs, flu viruses from humans continue to evolve their surface proteins, generically referred to as antigens, resulting in a tremendous diversity of novel flu viruses that can be transmitted to other pigs and also to humans," explains first author Nicola Lewis from the University of Cambridge.
根據(jù)eLife發(fā)布的一篇研究顯示，許多大洲分布的多樣性豬流感主要通過人類引入，新型生豬流感菌株有追守要的潛在風險。生豬流感病毒在很長一段光陰被以為是人類大型流行病的風險源，而2009年流行性HIN1病毒的來源讓人們把注意轉(zhuǎn)向從人類到豬的流感病毒傳播。劍橋大學的首席作者尼古拉·劉易斯(Nicola Lewis)解釋說：“人類身上的流感病毒一旦到了豬身上會讓病毒的表面蛋白發(fā)展，普通稱為抗原，繼而引起大量各種各樣的新型病毒，新型病毒可以傳染贈其他的豬或者人類?！?/p>
