Within a 4-year surveillance period for influenza A virus in pelagic birds, 351 influenza A strains were isolated from the trachea or cloaca of 3344 apparently healthy ducks, gulls, swans, terns and geese. The isolated influenza A viruses represent 14 subtypes. Their haemagglutinins (HA) were mainly related to avian HA, but also to the human HA H2 and to the swine HA Hswl. The neuraminidases (NA) were identified as avian, equine and human NA. The isolated influenza A strains include fowl plague-like viruses Havl Neql, strains with the surface antigen Hswl Nav4 and the subtype Hav7 Navl isolated from unconcentrated water samples. A subtype unknown to date, with the antigen formula H2 Nav4, was isolated from ducks. 8.2% of pekin ducks showed dual infections.
在对远洋鸟类甲型流感病毒进行的4年监测期内，从3344只看似健康的鸭、海鸥、天鹅、燕鸥和鹅的气管或泄殖腔中分离出351株甲型流感病毒株。分离出的甲型流感病毒代表14个亚型。它们的血凝素（HA）主要与禽HA相关，但也与人类HA H2和猪HA Hsw1相关。神经氨酸酶（NA）被鉴定为禽、马和人类NA。分离出的甲型流感病毒株包括禽瘟样病毒Hav1 Neq1、具有表面抗原Hsw1 Nav4的毒株以及从未浓缩水样中分离出的Hav7 Nav1亚型。从鸭中分离出一种迄今未知的亚型，其抗原公式为H2 Nav4。8.2%的北京鸭出现双重感染。
