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.
中國(guó)某生物實(shí)驗(yàn)室已經(jīng)追蹤到H7N9禽流感病毒源，該病毒的產(chǎn)生是因?yàn)闁|亞野鳥(niǎo)與華東家雞基因重組。
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.
中國(guó)科學(xué)研究院的專(zhuān)家未在豬身上追蹤到H7N9病毒，因此可以排除豬作為本次禽流感病原體的可能性。
