在透射电子显微镜下观察时,裂殖子的表膜呈现电子致密、结实而具有微纤维,从浆膜扩展约20毫微米。在免疫血清里,表膜变厚,内容疏松。疟原虫侵袭红细胞期间,裂殖子通过寄生原虫的红细胞空泡孔口时,它的表膜不能通过小孔而被留在细胞外的液体内。表膜由蛋白质或糖蛋白组成,可为胰蛋 When viewed under a transmission electron microscope, the merozoite’s mesenchyme appears electron dense, strong and has microfibrils, spreading about 20 nanometers from the serosal. In the immune serum, the surface of the film becomes thick and loose. During the invasion of erythrocytes by malaria parasites, the merozoites pass through the orifice of the parasite’s erythrocyte cavities and their superficial membranes can not remain in the extracellular fluid through the pores. Epithelial membrane composed of protein or glycoprotein, can be egg
