中文摘要:
為了早期預警高病原性家禽流行性感冒H5N1病毒經由遷徙性水禽帶毒入境及持續性監測禽流感在台灣野鳥的帶毒情形,2007年全年度自台北、台中、彰化、嘉義、台南、高雄、宜蘭、花蓮及金門的水鳥棲地主動性監測野鳥排遺檢體及少數死亡鳥體之被動性監測。共計進行4,150個採集樣本檢測,分離得24株禽流感病毒(分離率0.58%)及10株禽類副黏液病毒,24株禽流感病毒的亞型包括包括H1N1(n=2)、H1N2(n=1)、H3N8(n=4)、H4N6(n=10)、H6N1(n=1)、H7N6(n=3)、H7N7(n=1)、H8N4(n=1)、H10N7(n=1)等9個不同亞型的病毒,皆分離自鴨科鳥類的排遺檢體。監測之樣本來自鴨科鳥類為最多(n=2,645),鷸?科鳥類次之(n=1,147),再其次為鷺鷥科(n=317)、鷗科(n=20)及其他鳥類(n=21)。1月份在台南的四草溼地的一群野鴨排遺檢體中分離到3株H7N6亞型病毒,12月份同樣在台南四草溼地的野鴨排遺分離到1株H7N7亞型病毒,這些病毒經雞隻靜脈接種及病毒H基因蛋白酵素切割位分析鑑定病原性結果確定均為弱毒株。本監測結果發現,本年度候鳥季期間遷徙水鳥帶毒仍屬常見的弱毒型家禽流行性感冒病毒,沒有高病原性H5N1帶毒鳥禽之發現,顯示當前經由候鳥帶H5N1病毒入侵臺灣的風險仍低。
英文摘要:
The purpose of this surveillance is to make an early warning of highly pathogenic H5N1 and to realize the epidemiology of avian influenza in Taiwan’s wild birds. In 2007, a total of 4,150 specimens collected from wild birds of Taipei, Taichung, Chunghua, Chayi, Tainan, Koushong, Yielan, Hwalien, and Kingmen were examined for avian influenza viruses. Twenty-four viruses were isolated (0.58% isolated rate) and subtyped as H1N1 (n = 2), H1N2 (n = 1), H3N8 (n = 4), H4N6 (n = 10), H6N1 (n = 1), H7N6 (n =3), H7N7 (n =1), H8N4 (n = 1) and H10N7 (n = 1). All of these viruses were isolated from fecal specimens of duck species. Three H7N6 and one H7N7 viruses of low pathogenic strains (IVPI 0.0) were isolated from field ducks in wetland of Tainan. In conclusion, H5N1 did not been isolated in this study. This results indicated that the spread of H5N1 virus into Taiwan via the migratory birds was not occurred in 2007.
