中国2013年新型禽源H7N9甲型流感病毒的起源和进化基因组学:早期发现

Origins and evolutionary genomics of the novel 2013 avian-origin H7N9 influenza A virus in China: Early findings

Jiankui He, Luwen Ning, Yin Tong

摘要:

2013年3月和4月初,中国东部出现了一种新的禽源性甲型H7N9流感病毒(A-OIV)。在4月的第一周,18例感染病例已得到确认,自3月以来已有6人死亡。这种病毒作为一种潜在的大流行威胁已引起全球关注。在这里,我们使用进化分析来重建A-OIV病毒的起源和早期发展。我们发现A-OIV是由三种禽流感病毒株的重配衍生的,并且已经检测到大量的突变。我们的研究结果强调了对鸟类流感进行系统监测的必要性,并提供了证据表明,在禽类中混合新的遗传因子可能导致出现具有人类大流行潜力的病毒。

英文摘要:

In March and early April 2013, a new avian-origin influenza A (H7N9) virus (A-OIV) emerged in the eastern China. During the first week of April, the 18 infection cases have been confirmed and 6 people have died since March. This virus has caused global concern as a potential pandemic threat. Here we use evolutionary analysis to reconstruct the origins and early development of the A-OIV viruses. We found that A-OIV was derived from a reassortment of three avian flu virus strains, and substantial mutations have been detected. Our results highlight the need for systematic surveillance of influenza in birds, and provide evidence that the mixing of new genetic elements in avian can result in the emergence of viruses with pandemic potential in humans.
