附红细胞体的形态学研究

Morphological observation of Eperythrozoon

目的对附红细胞体形态学特点进行研究。方法通过光学显微镜、电子显微镜对附红细胞体的超微结构进行观察。结果光镜下对附红细胞体进行血液悬滴压片,发现附红细胞体以前、后、左、右、上、下等不同的方向翻滚、扭转运动;附红细胞体细胞体单个或聚合在一起存在于血浆中或附着在红细胞上。在透射电镜和扫描电镜下观察,附红细胞体是一种典型的原核生物,为环状、球状、盘状等多种形态,直径0.2-2.6μm不等;无细胞壁,仅有一层单层限制膜包裹,无明显细胞器和细胞核。结论附红细胞体属原核生物,为环状、球状、盘状等多种形态,无细胞壁,无明显细胞器和细胞核。

Objective To study the morphology of Eperythrozoon. Methods Ultrastructure of Eperythrozoon were observed by optic microscope and electron microscope in this study. Results Eperythrozoon was completely free organism, running with roll and twist in various directions in the plasma with microscopy. Eperythrozoon was single or aggregate that existed in blood plasma or attached to erythrocyte. Under scanning electron microscopy and transmission electron microscopy, Eperythrozoon was typical prokaryote （ranging in size from 0.2 to 2.6 μm） with form of ring, sphere, disk etc. Eperythrozoon had not cytoderm, obvious organellae and nucleus, and had only a single limited membrane. Conclusion Eperythrozoon was prokaryote with form of ring, sphere, disk etc. Eperythrozoon had not cytoderm, obvious organellae and nucleus.
