Abstract

To observe ultrastructure of rabbit Cysticercus pisiformis. Cysticercus pisiformis of naturally infected rabbit was collected and prepared for Transmission Electron Microscope (TEM) examinations. Under TEM, Cysticercosis pisiformis appeared to be ovoid form which comprised cyst wall, cyst fluid, scolex and cervical segment from outer to inner side. The structure of cyst wall was 3 layers (cortex, mesenchyina and parenchyma) of which the cortex was composed of 3 layers regular long strip shape cells the mesenchyina included a large number of glycogen granules and some bunches of fiber and the parenchyma included two kinds of cells besides glycogen granules and fiber. One kind was calcareous corpuscles cell and the other was spindle cell with bigger nuclear. The scolex comprised cortex, mesenchyina and parenchyma from outer to inner side of which the outside cortex laid a large number of regular microvilli the mesenchyina laid a large number of structureless fibrous material and glycogen granules and the parenchyma laid parenchymal cells, cortical cell, myoblast, flame cell, calcareous corpuscles cell, hamulus, collecting duct and excretory duct. The structure of cervical segment was similar with that of the scolex which included collecting duct and gather duct net.
