盘锦地区候鸟禽流感调查研究

Invstigation research on avian influenza infection of Migratory bird in Panjin

候鸟是禽流感病毒的自然宿主,对流感病毒的储存和蔓延起重要作用。本研究对辽河口湿地的迁徙候鸟进行了禽流感流行病学分析,在2012~2017年间,从双台子河口自然保护区内采集了各种野生水鸟,共采集野鸟样品棉拭384份、野鸟尸体脏器39份、环境水样500份、野鸟粪便3 355份,通过荧光定量RT-PCR方法进行检测(通用型、H5、H7和H9亚型),结果在多种候鸟粪便样品中检测到H5、H9亚型流感病毒。

Migrant is the natural host of avian influenza virus;it plays an important role of the storage and spread of influenza virus.The migrate of marsh of Liao estuary has been analyzed in this study.During 2012~2017,the samples of a series of wild waterfowl were collected,including cotton swabs of 384 wild bird,39 organs samples of dead wild bird body,500 water samples of environment,3 355 excrement samples from wild bird.The florescence quantitative RT-PCR method(universal,H5,H7 and H9 subtypes)was used to detect whether those samples contain avian influenza virus.The results showed H5 and H7 subtypes were detected in excrement samples from different species of migrate.
