【摘要】 目的对2004-2007年江西省流行性感冒(流感)病原学监测结果进行分析,进一步了解流感病毒的流行趋势,探索流感流行的规律。方法采集国家级监测哨点医院流感样患者的鼻咽拭子标本,用MDCK细胞分离流感病毒,用常量红细胞凝集抑制法(HI)鉴定病毒。结果2004-2007年共采集标本4564份,分离出流感病毒576株,分离率12.62%。其中A型H1N1亚型118株,占阳性株的20.49%,H3N2亚型238株,占阳性株的41.32%;B型V ictoria系108株,占18.75%,B型Yamagata系114株,占19.79%。结论2004-2007年江西省有A型H1N1亚型、H3N2亚型和B型V ictoria系、Yamagata系流感病毒流行,H3N2亚型流感病毒为主要流行优势株。更多还原

【Abstract】 Objective To analyze the results of etiological surveillance of influenza in Jiangxi from 2004 to 2007,find out the circulating trend of influenza virus and explore the epidemic pattern of influenza.Methods The nasopharyngeal swabs were taken from the influenza patients in sentinel hospitals at national level,influenza virus was isolated by using MDCK cell and identified by hemagglutination inhibition(HI) test.Results From 2004 to 2007,4564 samples were taken,and 576 strains of influenza virus were isolated(12.62%).Of these strains,118 were H1N1(20.49%),238 were H3N2(41.32%),108 were B/Victoria lineage(18.75%),114 were B/Yamagata lineage(19.79%).Conclusion From 2004 to 2007,influenza virus H1N1,H3N2,B/Yamagata lineage and B/Victoria lineage circulated in Jiangxi province,and H3N2 virus was predominated.更多还原
