支原体的大小为0.1~0.3μm,可通过滤菌器,常给细胞培养工作带来污染的麻烦。菌落小(直径0.1~1.0 mm),在固体培养基表面呈特有的“油煎蛋”状。无细胞壁,不能维持固定的形态而呈现多形性,对渗透压敏感,对抑制细胞壁合成的抗生素不敏感。革兰氏染色不易着色,故常用Giemsa染色法将其染成淡紫色。细胞膜中胆固醇含量较多,约占36%,对保持细胞膜的完整性具有一定作用。细胞膜含甾醇,比其他原核生物的膜
Mycoplasma size of 0.1 ~ 0.3μm, through the bacteria filter, often bring the trouble of cell culture work. Small colony (diameter 0.1 ~ 1.0 mm), in the solid medium surface was unique “fried egg ” shape. No cell wall, can not maintain a fixed shape and showing pleomorphic, osmotic pressure sensitive to antibiotics that inhibit cell wall synthesis is not sensitive. Gram stain is not easy to stain, it is often dyed with Giemsa staining lavender. Cell membrane cholesterol content, accounting for about 36%, to maintain the integrity of the cell membrane has a role. Cell membranes contain sterols, more than other prokaryotic membranes
