摘要
目的对郴州市2006年流行性感冒的病原学监测结果进行分析。方法采用流感样病例(ILI)的咽拭子标本用狗肾细胞(MDCK)进行病毒分离培养,采用血凝(HA)及血凝抑制(HI)方法进行流感病毒初筛及分型鉴定。结果全年共检测4所医院ILI咽拭子标本665份,分离到流感病毒40株,阳性分离率6.02%,经分型鉴定:A(H1N1)亚型35株,B型5株;疑似流感疫情ILI咽拭子标本29份,分离到流感毒株18株,阳性分离率62.07%,均为B型。结论2006年湖南省郴州市流感流行株为A(H1N1)亚型,有B型存在,未检测出A(H3N2)亚型。
Objective To analyze the pathogen of influenza- like illnesses （IL1） in Chenzhou City in 200.6. Methods The throat swab specimens of IL1 were cultivated with MDCK cells and the isolates of influenza viruses were identified by HA and HI, and then screened their genetic typings. Results All the year round, 665 throat swab spcimens of IL1 were collected from 4 sentinel hospitals, 40 influenza virus strains were isolated, the positive rate was 6.02 %. There were 35 A（HI- NI）subtype, and 5 B subtype. Furthermore, there were 29 IL1 spcimens from suspect epidemic influenza during 2006; 18 strains were isolated which were all B subtype, the positive rate was 62.07 %. Conclusion The epidemical influenza virus in Chenzhou in 2006 was A（H1N1） subtype and B subtype no A（H3N2） was found.
