摘要: 以恶性疟原虫可溶性抗原进行斑点免疫结合试验,检测53份恶性疟病人血清,结果有96.2%(51/53)阳性。检查非疟疾流行区宁夏的健康居民29人和上海献血员13人的血清,均属阴性。此法与内脏和什曼病、血吸虫病、肺吸虫病和姜片虫病等均无交义反应,表明此法对疟疾有较高的特异性。用恶性疟病人参改阳性血清作不同稀释度的反应观察发现,出现阳性反应的最高滴度为1:655 360,表明其敏感性亦很高。结果还表明,在同一批血样,此法的验出效果比常规微量ELISA和IFA的均高。

Abstract: In this paper, the results of dot-immunobinding assay (DIA) in tne diagnosis of falciparum malaria were reported. Among 53 sera from confirmed falciparum malaria cases from Hainan, 96,2%(51/53) showed positive reactions, while none of the 42 serum samples from blood donors in Shanghai and Ningxia Hui Autonomous Region where malaria was absent was found positive (Table 1). No cross reaction was observed with sera from cases of schistosomiasis, visceral leishmaniasis, paragonimiasis and fasciolopsiasis buski. The positive rate of DIA is higher than that of conventional ELISA(84.9%) or IFA(83.0%). It is recommended as a serological test of choice for the diagnosis of fal-ciparum malaria.
