摘要: 本文对采自我省不同疟区162份干血滴,包括恶性疟51例与间日疟111例,采用由当地分离的恶性疟原虫可溶性抗原进行ELISA试验,并用食蟹猴疟原虫(P.cynomolgi)替代抗原作对比,结果显示使用两种抗原的阳性符合率基本一致,但是用P.f抗原的几何平均滴度显著高于用P.c抗原者(371.76,324.68;P0.05),用P.f抗原测恶性疟患者血清阳性几何平均滴度显著高于用P.c抗原(527.8,383.71:t=1.72 P0.05)。在单纯间日疟区采集的49份血样使用P.c抗原的抗体阳性几何平均滴度显著高于P.f抗原,前者为388.84,后者为250.79(t=2.91 P0.01。)

Abstract: 162 blood samples (dry blood drops) including 51 cases of falciparum malaria and 111 cases of vivax malaria were collected from malaria regions of different endemicities in Yunnan Province. Soluble antigens prepared from a strain of P. Jalciparum isolated from a male patient suffered from subtertian malaria at Simao was cultured to be used in ELISA test. P. cynomolgi antigen was used as control. The result shows that the positive rates of the two antigens are basically identical. However, the GMRT with P. Jalciparum antigen is significantly higher than that with P. cynomolgi antigen (371.76: 324.68, P0.05) and the GMRT with homologous antigen is evidently higher than that with heterogeneous antigen (527.8:317.5, P0.001). When ELISA was applied to 49 blood samples collected from exclusively vivax malaria district, the GMRT of the antibody positivity was markedly higher with P. cynomolgi antigen than with P. falciparum antigen.
