用小鼠泡球蚴(MAH)和沙鼠泡球蚴(GAH)抗原ELISA对-20℃贮存3.5～6年的泡球蚴患者抗体作了检测。结果两种抗原敏感性各为98.1％和100％,与3.5～6年前的敏感性100％无统计学差异。用GAH抗原检测,50％病例抗体滴度下降,但38.5％病例抗体滴度增加,还有11.5％抗体滴度相同。在滴度下降病例中,76.9％下降1～2个滴度。贮存3.5～6年的抗体,其滴度在1:1600以上者仍占71.2％,且几何均数为原来用细粒棘球蚴液的1.1746倍,说明沙鼠泡球蚴抗原是检测泡蚴病的最适抗原。
Antibodies against hydatid cyst were stored at -20 ° C for 3.5-6 years using the mouse cysticercus (MAH) and the germ-cell cyst (GAH) antigen ELISA. Results The sensitivity of the two antigens were 98.1% and 100%, respectively, with no significant difference from the sensitivity of 3.5-6 years ago 100%. With GAH antigen test, 50% of cases of antibody titer decreased, but 38.5% of cases increased antibody titer, and 11.5% antibody titer the same. In the cases of decreased titer, 76.9% decreased by 1 or 2 titers. Antibody stored for 3.5-6 years showed a titer of 71.2% with the titer of 1: 1600, and the geometric mean was 1.1746 times that of the original Echinococcus granulosus solution The optimal antigen for the disease.
