采用ELISA检测蛔虫病流行区血清259例,其中193例粪检蛔虫卵阳性者,血清抗体的阳性符合率为93.8％:112例健康胎儿血清的阴性符合率为96.4％;56例肠道蠕虫卵阴性者血清的阴性率为82.1％;10例蛔虫卵阴性而肠道其它线虫卵阳性者血清的阳性率达30％。结果表明,此法诊断蛔虫感染具有较高的敏感性,但与肠道其它线虫感染血清有一定交叉反应。
Serum samples of 259 cases of ascariasis were detected by ELISA. The positive coincidence rate of 93 cases was 93.8% in 193 cases of fecal ascaris avian eggs: 96.4% in 112 healthy fetuses; 56 cases of intestinal worms eggs Negative serosal negative rate was 82.1%; 10 cases of ascaris egg negative and other intestinal nematode egg positive serum positive rate of 30%. The results show that this method is highly sensitive to diagnosis of Ascaris infection, but has some cross-reaction with the serum of other intestinal nematodes.
