在非易感的双脐螺体内曼氏血吸虫胞蚴最终将被血细胞包围和破坏,已有资料表明,双脐螺对血吸虫的不易感性主要源于血细胞介导的抗性。 为获得进一步证据,作者在非易感的13-16-R1螺体内植入琼脂糖微球包裹的曼氏血吸虫毛蚴,并将其与钻入双脐螺体的毛蚴转化而成的胞蚴进行比较。取8只螺,按下述方法植入毛蚴:将巴斯德管在火焰上拉出一尖细端,加入Chernin等渗盐溶液(CBSS)内的 Schistosoma mansoni in the non-susceptible endosomes will eventually be surrounded by blood cells and destruction of blood cells, data have been shown, the two snails insects susceptibility to schistosome mainly derived from blood cell-mediated resistance. To gain further evidence, the authors implanted agarose microspheres in the non-susceptible 13-16-R1 spirochete larvae of Schistosoma mansoni, and transformed them with the metacercariae transformed with miracidia Compare Take 8 spirochetes and implant the miracidia as follows: Pasteur pipettes a sharp, pointed end on a flame and is added to Chernin isotonic saline solution (CBSS)
