摘要: 应用成虫冰冻切片抗原作免疫酶染色试验(IEST)及间接免疫荧光抗体试验(IFAT),对比检测了 51份华支睾吸虫病患者和 50份健康人血清,两法的阳性率分别为 92%和 88%;假阳性率分别为 2%和4%,应用 IEST和IFAT对比检查 22份急性血吸虫病患者血清、20份慢性血吸虫病患者血清及 15份并殖吸虫病患者血清。IEST 出现的交叉反应率分别为 14%、5%和0;IFAT出现的交叉反应率分别为 14%、10%和0。表明两法诊断华支睾吸虫病均有较高的敏感性和特异性,并且抗原定位好。而 IEST不需要特殊仪器,更适合于现场应用。

Abstract: Both immunoenzymatic staining technique (TEST) and indirect fluorescent antibody test (IFAT) with frozen sections of adult Clonorchis sinensis as antigen were employed for detecting 51 cases with clonorchiasis and 50 healthy persons. The positive rate was 92% with I-EST and 88% with IF AT. The results showed no significant statistic difference (P0. 05). The false positive rates were 2% with the former and 4% with the latter. When sera from 22 cases with acute schistosomiasis, 20 cases with chronic schistosomiasis and 15 cases with paragonimiasis were examined by IEST and IF AT, cross-reactions were 14%, 5%and 0% with IEST, and 14%,10%and 0% with IFAT, respectively. The results showed that both IEST and IFAT are useful methods for serological diagnosis of clonorchiasis and the antigen on the gut was well demonstrated, while IEST might be more suitable in field surveys.
