【摘要】 目的:通过对2006年7月至2007年6月上海浦东地区流行性感冒(流感)的病原学监测数据的分析,了解上海浦东地区流感病原学特征,为今后这一地区的流行性感冒防治提供科学依据。方法:从类流感病人呼吸道采集咽拭子,接种狗肾传代(MDCK)细胞分离培养,进行红细胞凝集抑制试验和亚型的鉴定。结果:自2006年7月至2007年6月采集类流感患者标本199份,分离到61株流感病毒,总检出率为30.7%。其中A(H1N1)亚型、A(H3N2)亚型、B/Y亚型、B/V亚型分别为17株、40株、3株、1株,占总检出率的27.9%、65.6%、4.9%、1.6%。结论:上海浦东地区流感流行高峰期为夏季与冬季,2006年上海浦东地区的流行毒株以A(H1N1)亚型为主,2007年初的冬季流行毒株以A(H3N2)亚型为主。流感发病人群与性别无关。流感病毒的分离率与样本采集的质量有关。更多还原

【Abstract】 Objective: To find out the virological characteristics of influenza in Pudong Area and provide the scientific supports for influenza prevention in this area.Methods:The throat swab specimens were collected.Influenza virus was isolated with MDCK cells and then identified by hemagglutination inhibition test,HI.Results:A total number of 199 samples were collected during a period from July 2006 to June 2007,with 61 strains identified for influenza virus(30.7%).Among these strains,17 strains were A(H1N1) subtype(27.9%),40 A(H3N2) subtype(65.6%),3 B/Y subtype(4.9%) and 1 B/V subtype(1.6%).Conclusion:Summer and fall are the influenza fastigium in Pudong Area.A(H1N1) is the main influenza virus subtype in Pudong Area in 2006 and A(H3N2) is the main influenza virus subtype in winter 2007.The influenza population is independent of gender and the separation rate is correlated with the quality of samples.更多还原
