摘要: 应用辣根过氧化物酶联葡萄球菌A蛋白(HRP-SPA)为第二抗体作酶联免疫吸附试验(ELISA),华支睾吸虫卵阳性病人血清的检出率为88.8%,滤纸干血的检虫率为95.7%。138份健康人血清和滤纸干血的阴性符合率分别为95.7%和98.6%,与羊抗人IgG检测的结果相近。在现场普查中,HRP-SPA-ELISA检测滤纸干血样本与粪检虫卵的阳性符合率为90.3%,本法检测滤纸干血,可用于华支睾吸虫病的普查。

Abstract: Serum tests were made on 116 confirmed cases of clonorchiasis, 103(88.8%) of them showed positive, while only 6 (4.4%) were positive among 138 healthy people. Samples were collected on filter paper stripes. 111 (95.7%) cases were positive among 116 confirmed cases tested, but only 2 (1.5%) were positive out of 138 healthy persons. The results were similar to those obtained by sheep anti-human IgG.Animal experiment also showed that the SPA-ELISA can be used for the diagnosis of clonorchiasis.In an endemic area, stool positive rate was 8.8% (62/703). When checked with SPA-ELISA, the rate of conformity in both filter paper stripes and stool examinations was 90.3% (56/62). Among 641 serum tests from individuals negative in stool examinations, only 35 (5.5%) reacted positively. The authors suggested that SPA-ELISA with soluble clonorchis antigens could be used in a large scale seroepidemiological survey in endemic areas.
