作者等试用间接荧光抗体反应方法在萨尔瓦多6个疟疾低度流行地区进行监测疟疾流行的经历,补充各地区病例侦检站发现的现症病人和带虫者的资料,作为对本类型地区纵的考核疟疾防治效果的监测方法。本实验于1970年3月～1971年12月间进行,每年一般调查2次,用血清学和寄生虫学诊断方法检查各年龄组,重点为学龄儿童。血清样本分别与恶性疟、间日疟和三日疟等3种原虫制成的抗原进行间接荧光抗体试验,滴度在1∶20或更高者为阳性;厚血片样本经镜检100个视野找不到疟原虫者为阴性。
Authors tested Indirect fluorescent antibody responses Six malaria-endemic areas in El Salvador were monitored for malaria epidemics and were supplemented with information on patients and worms found in case-detection posts in various districts as an assessment of regional verticals Methods of monitoring the effectiveness of malaria control. The experiment was conducted between March 1970 and December 1971, and the general survey was conducted 2 times a year. Serum and parasite diagnostic methods were used to examine all age groups, with a focus on school-aged children. Serum samples were indirect fluorescent antibody test against the antigens of three species of Plasmodium falciparum, Plasmodium vivax and Plasmodium malariae, respectively, with a positive titer of 1:20 or higher; Vision can not find the negative for Plasmodium.
