摘　　要：目的研究2006-2010年盐城市恙虫病流行病学及病原学特点,探讨防制对策。方法系统收集恙虫病疫情,检测病人血液中恙虫病东方体及进行相关分子生物学研究,开展人群及动物恙虫病血清流行病学调查。结果盐城市2006-2010年共报告399例恙虫病病例,各县(市)均有疫情发生。每年疫情始于10月,11月为高峰,终于12月。病人以中老年为主。从1例病人血液中分离出恙虫病东方体,经分子技术测定及目的基因同源性比较,基因型别属Kawasaki。15岁以上人群血清抗恙虫病东方体IgG阳性率为1.85%,牛的血清阳线率为3.40%。结论盐城市各县(市)均发现恙虫病疫源地,疫情将持续流行,病原体基因型别未发生变化。Objective To analyze the epidemiological and etiological characteristics of scrub typhus during the past 5 years in Yancheng city,and investigate the prevention and control measures.Method Collecting the information about the epidemic of scrub typhus,detecting the Orientia tsutsugamushi in the patients＇ blood and conducting the related molecular biological study,carrying out the seroepidemiological study for people and animal scrub typhus.Results From 2006 to 2010,there were 399 scrub typhus patients in Yancheng city and distributing in all the counties（cities）.The epidemic started at October and ended at December,the peak time was November.The major patients were quinquagenarian.Orientia tsutsugamushi was isolated from 1 patient＇s serum and the genotype was Kawasaki determination by molecular techniques and comparison of gene homology.The IgG positive rate of Anti-Orientia tsutsugamushi in serum of people over the age of 15 was 1.85% and the IgG positive rate of cattle was 3.4%.Conclusions The epidemic focus of scrub typhus distributed in all the counties（cities） of Yancheng city and would last for long time,but the genotype hadn＇t changed.
