摘要: 应用马来丝虫成虫及牛丝虫成虫冰冻切片作荧光抗体试验(IFAT)及免疫酶染色试验(IEST),以检测对丝虫病人及健康人的敏感性、特异性和交叉反应性。两种抗原IFAT的敏感性和特异性分别为84.9~97.1%和90.3~97.1%;对钩虫、蛔虫感染者均无交叉反应。两种抗原IEST的敏感性和特异性分别为94.3~94.9%和97.1~100%;用牛丝虫成虫冰冻切片抗原更具有实用价值:IEST适用于现场。

Abstract: This article deals with the diagnostic values of IFAT and IEST in human filariasis with both frozen sections of Brugia malayi and Setaria cervi adult worms as antigens. The average positive and the false positive rates of IFAT with two antigens were 84.9-97.1%(45/53-102/105)and 2.9-9.7%(1/35-3/31) respectively, while no cross-reaction was observed in subjects infected with ascaris or hookworm. The average positive and the false positive rates of IEST with two antigens were 94.3-94.9% (99/105-56/59) and 0-2.9% (0/35-l/35) respectively. Both IFAT and IEST with two antigens for the diagnosis of human filariasis were considered to be of higher sensitivity and specificity, frozen sections of adult Setaria cervi being more economical and effective.
