禽流感病毒在野鸟种群中的分布特点

流感病毒在野生鸟类中分布广泛,特别是野生水禽被认为是流感病毒的天然储库,因此,野生鸟类在禽流感传播过程中具有不容忽视的作用.在总结分析以往有关禽流感病毒的研究文献资料的基础上,对全球各亚型禽流感病毒在野生鸟类中的流行情况、流感病毒在野鸟中的分布特点、野鸭中的流感病毒、候鸟迁徙与流感病毒传播、野鸟禽流感病毒感染的季节性特征和自然环境介质在流感病毒传播中的作用等几个方面情况进行初步的探讨,旨在能够对禽流感病毒在野生鸟类中的生态分布情况、特点规律及其野生鸟类在禽流感传播和流行方面的作用有更深入的了解.

Distribution Characteristics of Avian Influenza Viruses in Wild Birds

Avian influenza viruses (AIV) are widely distributed on wild birds. The wild waterfowls are particularly natural reservoirs of avian influenza virus. Migration of wild birds could not be overlooked during the prevalence of avian influenza virus. The paper discussed some questions based on the research data of AIV,including the prevalence of each subtype of AIV in global wild birds,distributing characteristic of AIV in wild birds,influenza viruses in ducks,the migratory birds and AIV transmission,season char...
