伯氏疟原虫(Plasmodium berghei)裂殖子前端有微线体及棒状体,二棒状体的小管汇合成总管通到类锥体。棒状体的内含物与裂殖子入侵红细胞有关。光学显微镜(简称光镜)下环形体中央的“空泡”实质上是红细胞胞质。滋养体质膜与红细胞膜形成镶嵌结构,有利虫体与宿主细胞物质交换。质膜上先有深色带状物质沉积,进而内凹形成胞口。虫体经胞口摄食,食物泡由单层膜包绕,内有疟色素。宿主胞质内凹有二层膜包绕,无疟色素,由虫体阿米巴运动形成。核分裂及细胞器分化是裂殖体期特征。雌配子体胞质核糖体多,内质网发达;雄配子体核糖体稀少,内质网贫乏。
Plasmodium berghei has microtubules and rods on the front of the merozoites. The tubules of the two rods merge to form a common tube that leads to the pyramids. The contents of the rod are related to the invasion of red blood cells by merozoites. Optical microscope (referred to as light microscopy) under the central ring “vacuole” is essentially the cytoplasm of red blood cells. Nourish the plasma membrane and the erythrocyte membrane inlaid structure, the beneficial host and host cell material exchange. The first dark plasma membrane material deposition, and then concave into the mouth. Insect by the oral feeding, food bubble surrounded by a single membrane, there are malaria pigment. The host cytoplasm concave with a two-layer membrane wrap, no malaria pigment, formed by the movement of the amoeba. Nuclear fission and organelle differentiation is a schizont stage feature. Female gametophyte cytoplasmic ribosome, endoplasmic reticulum; male gametocyte ribosome rare, poor endoplasmic reticulum.
