Usually, tiny colonies of ureaplasma urealyticum on the agar plate are counted under microscope for obtaining colony formation unit/ml ( CFU/ml ) and the pH change of the media is determined with color change unit/ml ( CCU/ml ).

• 脲支原体的定量计数,因其个体微小,一般需要在光学显微镜下计数平板上生长的菌落,得出菌落形成单位(CFU/ml)和在试管中观察液体培养基pH改变,依颜色变化程度确定颜色变化单位(CCU/ml)。
