曼氏血吸虫尾蚴在向童虫转化时,伴有多层表膜的形成,表膜可与ConA结合。这一转变通常发生在尾蚴钻穿哺乳类宿主健康皮肤时,但也可通过旋涡振荡,在37℃培养于复合培养基内的尾蚴来完成。作者用实验室培养的扁卷螺,曼氏血吸虫波多黎各株和CFi鼠作为研究材料,用荧光结合的ConA作表面标记,用透射电镜来观察表膜成熟的始发过程及其变化。 Schistosoma mansoni cercariae in the transformation to the squirrels, accompanied by the formation of multi-surface membrane, membrane binding with ConA. This shift usually occurs when cercariae penetrate the healthy skin of mammalian hosts, but can also be accomplished by vortexing and culturing cercariae in a complex medium at 37 ° C. The authors used laboratory-cultured flat snails, S. mansoni Puerto Rico and CFi mice as experimental materials, and fluorescence-conjugated ConA as surface markers. Transmission electron microscopy was used to observe the maturation process and its changes.
