为了进一步探讨间接荧光抗体试验在疟疾血清流行病学调查中的实用价值,对宝鸡市疟疾流行情况有一个概括的了解,我们于1990年9～10月在对宝鸡市疟疾发病情况进行流行病学调查的同时,采血测定了9 211名7～12岁儿童疟疾抗体水平。材料与方法一、调查对象全市十二个县区主要发病乡镇的7～12岁儿童进行了疟疾抗体测定。测试前调查均无疟疾感染史和近期患病史。二、标本采集耳垂采血制成直径1. 2cm滤纸血膜(浸透),含血量约20μl(内含血清10μl),编号,吹
In order to further explore the practical value of the indirect fluorescent antibody test in the epidemiological investigation of malaria, we have a general understanding of the prevalence of malaria in Baoji City. From September to October 1990, we conducted an epidemiological study on the incidence of malaria in Baoji City At the same time of the survey, blood samples were collected to determine malaria antibody levels in 9,211 children aged 7 to 12 years. MATERIALS AND METHODS A. Survey The malaria antibody test was conducted in children aged 7 to 12 years in the towns and townships in the twelve county districts of China. There was no history of malaria infection and recent history of illness before the survey. Second, specimens collected earlobe blood made diameter 1. 2cm filter paper blood film (soaked), containing blood about 20μl (containing serum 10μl), number, blow
