[目的 ]比较食蟹猴疟原虫 (P c.)和恶性疟原虫 (P f.)两种抗原在不同疟区人群疟疾抗体检测的实用性。 [方法 ]1997年 5～ 10月在海南省间日疟和恶性疟混合流行区及河南省单纯间日疟区用P c 和P f 两种抗原测试人群疟疾抗体。 [结果 ]在海南省间日疟和恶性疟混合流行区P c 和P f 两种抗原检测人群疟疾间接荧光抗体阳性率分别为 37 4%和 31 3% ,其阳性符合率为 83 9% ;河南省单纯间日疟流行区的P f和P c两种抗原阳性率分别为 2 3 0 %和 9 7% ,阳性GMRT分别为 42 9%和 2 9 3%。 [结论 ]间日疟和恶性疟混合流行区P f和P c两种抗原均可用于人群疟疾抗体的检测 ,而单纯间日疟地区则以P c 抗原为优。
[Objective] To compare the practicability of malaria antibody detection in two populations of Plasmodium macaque (P c.) And Plasmodium falciparum (P f.) In different malaria endemic areas. [Method] From May to October 1997, malaria antibodies were tested in two populations of P. falciparum and P. falciparum in Hainan Province. [Results] The positive rates of indirect fluorescent antibody of malaria were 37 4% and 31 3%, respectively, with a positive coincidence rate of 83 9% in Hainan Province for the detection of both P c and P f antigens in the mixed epidemic area of Vivax malaria and Plasmodium falciparum. The positive rates of P f and P c in the endemic areas of V. vivax in Henan Province were 230% and 97% respectively, and the positive GMRTs were 42.9% and 293% respectively. [Conclusion] Both P f and P c antigens of P. vivax and P. falciparum can be used for the detection of malaria antibodies in humans, while p c antigen is superior in P. vivax alone.
