细粒棘球蚴实验感染鼠体液免疫动态的初步结果

采用胶乳凝集试验(LA)、酶联免疫电转移印斑试验(EITB)、酶联免疫吸附试验(ELISA)、斑点-ELISA试验(Dot-ELISA)以及免疫荧光试验(IFA)5种免疫血清学方法,对细粒棘球蚴实验感染鼠的抗体进行了动态观察,结果表明这5种检测方法均能检出抗体,其中以Dot-ELISA及IFA最敏感,于感染后2周即有部分鼠测到抗体。ELISA、EITB和LA出现阳性反应的时间依次为4周、2月和3月。感染8月及1年的病鼠全部阳性,而对照鼠则全部阴性。

Immunological humoral response in mice experimentally infected with Echinococcus granulosus, preliminary result of kinetic observation

5 serological methods included latex agglutination test (LA), enzyme-linked immunoelectrotransfer blot (EITB), enzyme-linked immunosorbent assay (ELISA), dot-enzyme-linked immunosorbent assay (Dot-ELISA) and immunofluorescence antibody test (IFA) were used to trace the kinetic changes of the humoral response in NIH mice experimentally infected with protoscolex of Echinococcus granulosus. Results showed that Dot-ELISA and IFA were able to detect antibodies 2 wk after infection while ELISA, EITB and LA gave positive reactions 4 wk, 2 mos and 3 mos after infection respectively. Therefore Dot-ELISA and IFA were considered to be the most sensitive ones among the 5 methods used. All infected mice gave positive reactions at 8 and 12 mos but none of the normal control mice showed any reaction throughout the period of observation (Fig. 1).
