摘要:

目的:探讨鼠伤寒杆菌核糖体制剂对血吸虫抗原的佐剂作用。方法:小鼠分别用鼠伤寒杆菌核糖体制剂(STRP)加日本血吸虫成虫抗原(SWA)和日本血吸虫成虫抗原免疫后,其体液免疫水平用ELISA检测,保护性免疫力用减虫率表示。结果:用STRP+SWA免疫的小鼠的抗体水平显著高于单用SWA免疫的小鼠。尾蚴攻击感染后,STRP+SWA免疫组小鼠和SWA免疫组小组的减虫率,分别为47%和17%,前者高于后者。结论:STRP可以增强小鼠对血吸虫抗原的体液免疫应答反应,并且可诱导小鼠产生较强的抗尾蚴攻击感染能力。

Abstract:

AIM:To explore the adjuvant effect of Salmonella typhimurium ribosome preparation (STRP)on adult schistosome antigen (SWA). METHOD:Mice were immunized with STRP+SWA and SWA, respectively.Humoral immunity levels of mice were detected by ELISA and protective immunity of mice were indicated by worm reduction rate. RESULTS:The antibody level of mice immunized with STRP+SWA was significantly higher than that of mice immunized with SWA. After cercariae challenge infection,the worm reduction rate of mice immunized with STRP+SWA was also significantly higher than that of mice immunized with SWA. CONCLUSION:It is suggested that STRP can enhance the humoral response of mouse to SWA and elicit stronger resistance to schistosome cercariae challenge infection.
