为了调查流感病毒在南半球野生水鸟中的流行情况，于2004年12月在澳大利亚苍鹭岛采集了燕鸥的粪便样本。共分离到6株H2N5流感病毒。这是澳大利亚首次从岸鸟中分离到H2亚型。系统发育分析表明，M基因属于美国禽流感病毒谱系，其余基因属于欧亚谱系，表明在自然界中自由飞行的鸟类中欧亚和美洲谱系病毒之间存在基因重排。
To investigate the prevalence of influenza viruses in feral water birds in the Southern Hemisphere, fecal samples of terns were collected on Heron Island, Australia, in December 2004. Six H2N5 influenza viruses were isolated. This is the first report of the isolation of the H2 subtype from shore birds in Australia. Phylogenetic analysis revealed that the M gene belonged to the American lineage of avian influenza viruses and the other genes belonged to the Eurasian lineages, indicating that genetic reassortment occurs between viruses of Eurasian and American lineages in free flying birds in nature.
