A top Chinese biology lab has ascribed the H7N9 avian influenza to genetic reassortment of wild birds from east Asia and chickens from east China.
中国某生物实验室已经追踪到H7N9禽流感病毒源,该病毒的产生是因为东亚野鸟与华东家鸡基因重组。
The researchers from the Chinese Academy of Sciences found that no genes in H7N9 were traceable to pigs, thus excluding pigs as intermediate hosts for the deadly new strain of bird flu.
中国科学研究院的专家未在猪身上追踪到H7N9病毒,因此可以排除猪作为本次禽流感病原体的可能性。
