| 摘 要： | 禽流感病毒的血凝素(hemagglutinin,HA)和神经氨酸酶(neuraminidase,NA)均易发生抗原漂移和抗原转换,可突变出快速感染人类并致病的亚型,特别是H5N1型具有从感染其他动物种属的流感病毒中获得基因并迅速转变的能力,威胁人类健康。世界候鸟的迁徙更使全球面临禽流感危急,本文就禽流感的病毒特征、感染机制及其防治和鸟类迁徙对禽流感传播的影响进行综述。

| Abstract: | Hemagglutinin(HA) and Neuraminidase(NA) of influenza viruses are easy to have antigenic drift and antigenic shift, and new pathogenic subtype which is able to infect humans can be formed by such viral mutations.Genetic reassembly which always happens in H5N1 subtype accelerates the threat of avian influenza Aviruses to human being.In addition, bird migration contributes to the global spread of emerging infectious disease.Therefore, we review current knowledge regarding the harm, pathological properties, pathogenicity of avian influenza viruses and discuss the influence of bird migration to the global spread of the viruses. |
