摘　　要：目的采用血清学试验和RT-PCR方法在2006-2008年5月期间从华东地区家禽中分离到473株禽流感病毒(AIVs),其中家鸭AIVs的分离率最高(14.7%),鸡AIVs分离率最低(2.92%)。共分离到H1、H3、H4、H6、H9、H10、H11七种HA亚型低致病性禽流感病毒(LPAIVs),其中H3亚型LPAIVs在家禽中的分布占优势。禽流感病毒的分离呈现一定的季节性,一般春秋冬三个季节分离率相对较高。From 2006 to 2008, 473 strains of low pathogenicity avain influenza viruses （LPAIVs） with different HA subtypes were isolated from poultry in eastern China, in which the isolation rate of LPAIVs appeared to be the highest in do- mestic ducks （14.7%） and lowest in chicken （2.92%）. In these LPAIVs isolated, there were 7 HA subtypes, including H1, H3, H4, H6, H9, H10 and Hll, among which H3 was the predominant subtype in poultry. In addition, seasonal variations on the isolation rate could be demonstrated with a peak of the isolation rate from October to March.
