Quality Level

Application

用于分化尿素代谢微生物。弱的脲酶生产者如克雷伯氏菌、肠杆菌等也可以分化。根据 Thal 和 Chen(1955)的研究,假结核耶尔森菌(尿素阳性)来自鼠疫耶尔森氏菌(尿素阴性)。

Other Notes

从粪便样本中筛选肠道致病菌
我们现提供两种类型的培养基:GranuCult®优质颗粒状培养基和NutriSelect®高性价比粉末状培养基,满足用户不同层次的需求。
商标后的品级称号basic(基础)、plus(加强)或prime(特级)代表产品的不同质控水平,从基础的质控到标准质控加强版到全面合规的特级质控水平。

Preparation Note

将21g 溶解在960 mL蒸馏水中。在121°C下高压蒸汽灭菌15分钟。冷却至后50°C,通过无菌操作添加50ml(10 小瓶)无菌过滤的40% 尿素溶液(货号08582)并冷却为斜面。
