一般說明
Middlebrook 7H10琼脂培养基推荐用于结核分枝杆菌的分离、培养和敏感性试验。Middlebrook培养基由许多无机盐组成,有助于分枝杆菌的生长。由柠檬酸钠形成的柠檬酸有助于保留溶液中的无机阳离子。甘油可提供碳和能量。Middlebrook OADC生长补充剂(M0678)含有油酸、牛白蛋白、氯化钠、葡萄糖和过氧化氢酶。油酸和其他长链脂肪酸是分枝杆菌代谢所必需的。一些游离脂肪酸对分枝杆菌是有毒的,但白蛋白与这些脂肪酸结合后,防止了对分枝杆菌的毒性作用。葡萄糖是一种能量来源。过氧化氢酶中和有毒过氧化物。孔雀石绿部分抑制其他细菌。
應用
Middlebrook 7H10琼脂培养基是结核分枝杆菌分离、培养和敏感性试验的选择性培养基。分枝杆菌在肉汤培养基中生长最快,因此可以进行细菌种类的初步分离。它经济、易于制备,可以帮助早期检测抗酸性,培养分枝杆菌种类。

準備報告
将19.47 g Middlebrook 7H10 Agar Base 悬浮 900 ml蒸馏水中。加入5 ml甘油(Cat.No. 49767).加热至沸腾以完全溶解培养基。以180 ml的量分配至每个锥形瓶,并在121°C,15 磅的压力下高压灭菌10分钟。冷却至45°C,无菌添加20 ml的 Middlebrook OADC 生长补充剂(Cat.No.M0678)。充分混合,倒入带螺旋盖的试管。注意:制备好的培养基,在接种前、后均需放置在暗处。
