摘　　要：目的：通过对2014-10~2015-03佳木斯市流感病毒分离结果进行分析,了解我市流感病毒的型别和亚型,评估流感的流行态势,为流感防治提供科学依据。方法：采集流感样病例（ILI）咽拭子标本,接种狗肾传代（MDCK）细胞分离培养,采用血凝抑制方法（HAI）进行流感病毒型别鉴定。结果：2014-10~2015-03共检测ILI咽拭子标本1040份,MDCK细胞分离到流感病毒37株,阳性分离率为3.56%,经分型鉴定A型H3N2亚型28株（2.69%）,B型Yamagata系9株。结论：2014-10~2015-03佳木斯市流感优势毒株为A型H3N2亚型,同时有B型Yamagata系毒株的存在。Objective： To analyze the data of influenza virus isolation from Jiamusi City during 2014- 2015 and to understand the subtypes of influenza virus and to assess the epidemic situation in Jiamusi so that a scientific basis can be provided for the prevention and treatment of influenza. Methods： The specimens from influenza like illness（ ILI） were collected. The Viruses were isolated with MDCK cell and identified with HAI. Results： 1040 ILI pharyngeal swab specimens were detected in October 2014- March 2015. A total of 37 influenza strains were obtained from MDCK and the positive rate was 3. 56%. 28 of them were identified as subtype A（ H3N2）,and 9 of them were identified as subtype B（ Yamagata）. Conclusion： The main type is influenza type A（ H3N2） in Jiamusi City. Subtype B（ Yamagata） is also detected.
