摘要
目的：及时了解长春市流感病毒优势株的变化,分析预测流感流行的趋势和特点,为流感防治提供科学依据。方法：采集门诊流感样病人的咽拭子和漱口液,接种于MDCK细胞进行病毒分离和分型鉴定。结果：2007年10月～2008年3月长春市CDC从299例流感样病例标本中分离到94株流感病毒,分离阳性率为31.44%,其中H3N2型41株（占43.62%）,B-victoria系36株（占38.30%）,B-yamagata系17株（占18.08%）。结论：2007～2008年度长春市流感的流行情况较为平静,H3N2型,B-victoria系,B-yamagata系成为流感流行的优势株,与上一监测年度（H1N1型,H3N2型）不同。
Objective：To detect the changes of the predominant strains of influenza and forecast the trends and characters of influenza so as to provide scientific bases for the prevention of influenza.Methods：Throat swab and gargling specimens were collected from influenza-like patients.Influenza viruses were isolated by MDCK cells and typed by hemagglutination inhibition（HI） test.Results：From October 2007 to March 2008,299 specimens were collected from influenza-like patients,from which 94 strains of influenza viruses were isolated with the isolation rate of 31.44%.Thereinto,41 strains were identified as H3N2（account for 43.62%）,36 strains as B-victoria（account for 38.30%） and 17 strains as B-yamagata（account for 18.08%）.Conclusion：The case is calm in Changchun during 2007-2008.The predominant strains are H3N2,B-victoria and B-yamagata which are different from the predominant strains（H1N1and H3N2） of the past.
