本文用人、羊、牛肝棘球蚴液抗原对４３例泡球蚴病，８１例非泡球蚴病患者和７５例健康人进行了斑点免疫结合试验（ＤＩＢＡ）。结果显示：人、羊、牛棘球蚴液抗原检测的阳性率各为１００％、１００％和８６．０％，前二者与后者差异显著（Ｐ均＜０．０５）；假阳性率分别为０．６％、０．６％和０％，三者无显著差别。泡球蚴患者抗体滴度在１∶４００～１∶６４００范围者，前两者均占９７．７％，显著高于后者的５６．１％（Ｐ均＜０．０１）。抗体几何平均滴度前两者分别是后者的５．１８倍和４．６２倍，差异均有高度显著性（Ｐ均＜０．０１）。说明在诊断泡球蚴病时宜用前两种抗原。
In this study, 43 cases of alveolar echinococcosis, 81 cases of non-alveolar echinococcosis and 75 healthy persons were immunized with DIBA by using human, sheep and Echinococcus granulosus antigen. The results showed that the positive rates of human, sheep, and Echinococcus granulosus were 100%, 100% and 86.0%, respectively, with significant difference (P <0.05). The false positive rate Respectively, 0.6%, 0.6% and 0%, no significant difference between the three. Patients with metacercariae antibody titer in the range of 1: 400 ~ 1: 6400, the former two accounted for 97.7%, significantly higher than the latter 56.1% (P all <0.01). The first two geometric mean titers of antibody were 5.18 times and 4.62 times higher than the latter respectively, the differences were highly significant (all P <0.01). Description in the diagnosis of alveolar disease should be the first two antigens.
