Birds in the order Charadriiformes were sampled at multiple sites in the eastern half of the continental USA, as well as at Argentina, Chile, and Bermuda, during 1999-2005, and tested for avian influenza virus (AIV). Of more than 9,400 birds sampled, AIV virus was isolated from 290 birds. Although Ruddy Turnstones (Arenaria interpres) comprised just 25% of birds sampled, they accounted for 87% of isolates. Only eight AIV isolations were made from birds at four locations outside of the Delaware Bay, USA, region; six of these were from gulls (Laridae). At Delaware Bay, AIV isolations were predominated by hemagglutinin (HA) subtype H10, but subtype diversity varied each year. These results suggest that AIV infection among shorebirds (Scolopacidae) may be localized, species specific, and highly variable in relation to AIV subtype diversity.
1999年至2005年期间，在北美洲大陆东半部的多个地点以及阿根廷、智利和百慕大对鸻形目鸟类进行了采样，并检测了禽流感病毒（AIV）。在超过9400只采样鸟类中，从290只鸟类中分离出了AIV病毒。尽管翻石鹬仅占采样鸟类的25%，但它们却占分离株的87%。在美国特拉华湾地区以外的四个地点，仅从鸟类中分离出8株AIV；其中6株来自鸥类（鸥科）。在特拉华湾，血凝素（HA）亚型H10在AIV分离株中占主导地位，但每年亚型多样性有所不同。这些结果表明，滨鸟（鹬科）中的AIV感染可能是局部性的、具有物种特异性，并且在AIV亚型多样性方面高度可变。
