Abstract

The indirect ELISA was used to detect antibodies to influenzavirus A in the sera of wildfowl from the Donana National Park. Of the 712 birds examined, 44 (6.2%) were seropositive. Positive birds belonged to 10 of the 13 species studied. Infection rates varied widely: spoonbill (Platalea leucorodia, 32.2%), mallard (Anas platyrhynchos, 9.9%), gadwall (Anas strepera, 8.6%), red-crested pochard (Netta rufina, 8.1%), pochard (Aythya ferina, 6.4%), shoveler (Anas clypeata, 5%), great crested grebe (Podiceps cristatus, 4.3%), avocet (Recurvirostra avosetta, 3.1%), grey heron (Ardea cinerea, 3.1%) and coot (Fulica atra, 0.8%). Although infection rates were not high, the wide range of avian species susceptible to influenzavirus A suggests circulation of the virus amongst wildfowl at Donana.

摘要

采用间接酶联免疫吸附测定法检测多纳纳国家公园野生禽类血清中的甲型流感病毒抗体。在检测的712只鸟类中，44只（6.2%）血清呈阳性。阳性鸟类属于所研究的13个物种中的10种。感染率差异很大：琵鹭（白琵鹭，32.2%）、绿头鸭（绿头鸭，9.9%）、赤膀鸭（赤膀鸭，8.6%）、红胸秋沙鸭（红胸秋沙鸭，8.1%）、普通秋沙鸭（普通秋沙鸭，6.4%）、琵嘴鸭（琵嘴鸭，5%）、凤头鸊鷉（凤头鸊鷉，4.3%）、反嘴鹬（反嘴鹬，3.1%）、苍鹭（苍鹭，3.1%）和白骨顶鸡（白骨顶鸡，0.8%）。虽然感染率不高，但对甲型流感病毒易感的鸟类种类繁多，这表明该病毒在多纳纳的野生禽类中传播。
