The quantification of colony forming units (cfu), turbidity, and optical density at 600 nm (OD600) measurements were used to evaluate Mycobacterium tuberculosis growth. Turbidity and OD600 measurements displayed similar growth curves, while cfu quantification showed a continuous growth curve. We determined the cfu equivalents to McFarland and OD600 units.
采用集落形成单位（cfu）计数、浊度和 600nm 吸光度（OD600）测量来评估结核分枝杆菌的生长情况。浊度和 OD600 测量显示出相似的生长曲线，而 cfu 定量则显示出连续的生长曲线。我们确定了 cfu 与麦氏和 OD600 单位的等效值。
