原生动物分子式：CAS号：性质：单细胞、无细胞壁、能运动、通常为无色和摄食型的真核微生物的通称。它们以其细胞大(数微米至数毫米)和有真核而与细菌相区别；以其有叶绿素和无细胞壁而与藻类相区别；以其能运动和无细胞壁而与真菌(包括酵母菌)相区别。广泛分布于自然界。多数自由生活在淡水、海水、土壤、污水和动物肠道(尤其是反刍动物的瘤胃和白蚁肠道)等处。少数为寄生种，引起人类、脊椎动物和无脊椎动物的病害，如人类的疟疾、阿米巴痢疾和阴道滴虫病等。根据运动和生殖方式的不同，原生动物一般分四纲。(1)鞭毛虫纲：借鞭毛运动，无性生殖为纵裂，有性生殖有同配与异配两方式，如绿眼虫(Euglenaviridis)。(2)肉足虫纲：无一定体形，靠伪足运动，如大变形虫(Amoebaproteus)。(3)孢子虫纲：无运动胞器，均为寄生，有复杂的生活史，以产生孢子进行繁殖。如疟原虫(Plasmodium spp)。(4)纤毛虫纲：体表有大量具运动和取食能力的纤毛；细胞核有大、小之分，大核一个，小核数量不等；无性生殖为横裂，有性生殖为接合。如大草履虫(Parameciumcaudatum)。已知原生动物约3万种，与人类关系密切。它们是浮游生物的重要组分，可作鱼类等经济动物的直接或间接饵料；是水质、海流、污水处理或探矿(石油)的重要指示生物；部分种类是人或许多经济动物的病原体。
