目的 :了解鼠疫在人群中抗体滴度的消涨和阳性转归变化。方法 :应用间接血凝实验对耿马县1990年12月确诊鼠疫感染者(显性感染和隐性感染) ,进行了血清学追踪观察。结果 :鼠疫感染者F1抗体滴度和几何平均滴度1990年12月为1∶20～20480 ,GMT104 ,1991年6月下降1∶20～1280 ,GMT64 02 ,9月1∶20～1280 ,GMT63 49 ,呈逐渐下降趋势。鼠疫感染者78 38 %在1年内仍有F1抗体存在 ,21 62 %1年内F1抗体消失。结论 :间接血凝实验在鼠疫流行现疫区对鼠疫感染者具有实用的追溯诊断价值
Objective: To understand the drop in antibody titer and the positive outcome of the plague in the population. Methods: Indirect hemagglutination tests were performed on serological tracing of plague-infected patients (dominant infection and recessive infection) in Gengma County in December 1990. Results: The titer and geometric mean titer of F1 antibody in plague patients were 1:20 ~ 20480 in December 1990, 1:20 ~ 1280 in June 1991, GMT64 02, September 1:20 ~ 1280, GMT63 49, showing a gradual downward trend. 78% of plague-infected persons still had F1 antibody within 1 year, and 21 62% of F1 antibody disappeared in 1 year. Conclusion: The indirect hemagglutination test has practical retrospective diagnostic value in plague-infected areas
