近年来华东地区家鸭中禽流感病毒的亚型分布

目的]为了研究近年来华东地区家鸭中禽流感病毒的亚型分布情况.方法]对2002-2006年分离自华东地区家鸭的180株禽流感病毒的HA亚型和其中88株禽流感病毒的NA亚型分别进行了测定.结果]近年来华东地区家鸭中至少存在9种HA亚型和6种NA亚型组成的H1N1,H3N1,H3N2,H3N8,H4N6,H5N1,H5N2,H6N2,H6N8,H8N4,H9N2,H10N3,H11N2共13种亚型的禽流感病毒.结论]华东地区家鸭中有多种亚型的禽流感病毒分布,应加强家鸭禽流感的监测和防制工作.

Distribution of Avian Influenza virus Subtypes amongDomestic Ducks in Eastern China

Objective] To identify the distribution of avian influenza virus subtypes among domestic ducks in eastern China. Methods] One hundred and eighty avian influenza viruses isolated from domestic ducks between 2002 and 2006 were tested for their Hemagglutinin subtypes, and 88 of them were followed by monitoring for Neuraminidase (NA) subtypes. Results] At least 9 HA subtypes and 6 NA subtypes, which constituted 13 subtypes of avian influenza viruses in domestic ducks, including H1N1, H3N1, H3N2, H3N8, H4N6, H5N1, H5N2, H6N2, H6N8, H8N4, H9N2, H10N3 and H11N2, were circulating in eastern China in recent years. Conclusion] Multiple subtypes of avian influenza viruses were distributed among domestic ducks in eastern China in recent years. The surveillance and prevention of avian influenza viruses in domestic ducks must be strengthened.
