摘要:   目的: 探讨重组日本血吸虫26 k Da G S T 抗原免疫家兔后抗体水平动态变化。方法: 家兔随机分为免疫组与佐剂对照组,免疫组用纯化重组日本血吸虫 26 k Da G S T 抗原加福氏佐剂免疫;佐剂对照组用0.85% 盐水加福氏佐剂免疫。免疫后,每兔逐周取耳静脉血,采用酶联免疫吸附试验( E L I S A) 检测血清中特异性抗体水平。结果: 免疫组家兔从免疫后第4 w k 起血清中特异性抗 G S T 抗体升高,且维持在较高的水平达65 w k。结论: 重组日本血吸虫 26 k Da G S T 抗原免疫家兔后,特异性抗 G S T 抗体水平较对照组明显升高,且至少能维持 1 年。

Abstract:  AIM: To investigate the dynamics of the anti GST antibodies in rabbits immunized with recombinant 26 kDa GST of Schistosoma japonicum . METHODS: The specific antibodies were detected weekly by GST ELISA in rabbits vaccinated with purified recombinant 26 kDa GST antigen of S.japonicum plus FCA/IFCA;rabbits immunized with 0.85% saline plus FCA/IFCA served as control group. RESULTS: The specific anti GST antibodies began to increase at week 4 post immunization,the mean OD value in rabbits vaccinated with recombinant GST could reach 1.03±0.46(adjuvant control group only 0.42±0.04).The experiment was completed at week 65 post immunization when the mean OD values for specific anti GST antibody in immunized rabbits were 0.94±0.26(0.29±0.16 in the control group). CONCLUSION:Strong anti GST antibody responses could be induced in rabbits vaccinated with recombinant 26 kDa GST of S.japonicum.
