The role of migrating birds as potential vectors for avian influenza virus (AIV) was investigated. We captured 543 migrating passerines during their stopover on the island of Helgoland (North Sea) in spring and autumn 2001. These birds were sampled for avian influenza A viruses (AIV), specifically the subtypes H5 and H7. For virus detection, samples were taken from 1) short-distance migrants, such as chaffinches (Fringilla coelebs; n = 131) and song thrushes (Turdus philomelos; n = 169); and 2) long-distance migrants, such as garden warblers (Sylvia borin; n = 142) and common redstarts (Phoenicurus phoenicurus; n = 101). Virus isolation assays failed to identify AIV. Therefore, regarding the actual low number of samples, we speculate that the tested four species of passerines were not infected by AIV, indicating that the passerine species examined in this study may play only a minor role as potential vectors of AIV.
对候鸟作为禽流感病毒(AIV)潜在传播媒介的作用进行了调查。2001年春秋两季,我们在黑尔戈兰岛(北海)对543只迁徙中的雀形目鸟类进行了环志。这些鸟类被采集了甲型禽流感病毒(AIV)样本,特别是H5和H7亚型。为进行病毒检测,样本取自1)短距离迁徙鸟类,如苍头燕雀(Fringilla coelebs;n = 131)和歌鸫(Turdus philomelos;n = 169);以及2)长距离迁徙鸟类,如花园莺(Sylvia borin;n = 142)和普通红尾鸲(Phoenicurus phoenicurus;n = 101)。病毒分离试验未能鉴定出AIV。因此,鉴于实际样本数量较少,我们推测所检测的四种雀形目鸟类未感染AIV,这表明本研究中所检测的雀形目鸟类作为AIV潜在传播媒介可能仅起次要作用。
