本文报道小鼠感染曼氏血吸虫过程中控制免疫抑制的刺激物的性质。已证明免疫抑制是由成虫而非虫卵引起的,并在有效治疗后完全消失。此外,有间接证据表明参与免疫抑制的抗原来源于血吸虫体表外膜。实验及对照组用相同年龄、重25～35克的雄性小鼠。经皮下注射40条曼氏血吸虫尾蚴进行感染。灌洗肝及肠系膜血管,每鼠平均发现14±6条虫。扁卷螺的单性感染是1只扁卷螺仅用1个毛蚴进行感染。对绵羊红细胞(SRBC)的空斑形成细胞
This article reports the nature of stimuli that control immunosuppression in mice infected with Schistosoma mansoni. Immunosuppression has been shown to be caused by adult but not insect eggs and disappears completely after effective treatment. In addition, there is indirect evidence that the antigens involved in immunosuppression originate from the outer membrane of the schistosome. Experimental and control groups with the same age, weighing 25 to 35 grams of male mice. Subcutaneous injection of 40 S. mansoni cercariae infection. Irrigation of liver and mesenteric vessels resulted in an average of 14 ± 6 worms per mouse. Flat snails unilateral infection is a flat snail with only 1 miracidia infection.
