目的：探究缩小膜壳绦虫的生长发育和形态演变过程。方法：在大鼠和赤拟谷盗间建立缩小膜壳绦虫生活史循环。用光镜和扫描电镜观察似囊尾蚴形态及体表超微结构。结果；光镜下发现似囊尾蚴的发育包括成熟期、有泡期和保护性外膜形成期三个阶段。扫描电镜下感染后２ｗｋ的成熟期体表有筛状微孔。感染３ｗｋ后，有泡状隆起，感染后４ｗｋ，体表外膜形成所覆盖，由泡状表膜逐渐形成表面光滑的囊壁。结论：本研究建立了缩小膜壳绦虫感染动物模型。首次报道似囊尾蚴的发育包括成熟期、有泡期和保护性外膜形成期。
Objective: To explore the narrowing of tapeworm growth and development and morphological evolution. METHODS: A cycle of narrowing the life cycle of tapeworm was established between rats and red moth. Observation of Cysticercus cellulosae morphology and body surface ultrastructure with light microscope and scanning electron microscope. Results; Under the light microscope, the development of Cysticercus cellulosae was found to include three stages of maturation, bubbling and protective outer membrane formation. Scanning electron microscopy 2wk after the maturity of the body surface with sieve-like micropores. After infection 3wk, bubbly bulge, 4wk infection, the formation of the surface of the outer membrane covered by the bubble-shaped surface membrane gradually formed a smooth surface. Conclusion: This study established a narrowing of tapeworm infected animal models. For the first time reported cysticercosis development, including maturation, there is a bubble period and the formation of protective outer membrane.
