一般說明
MH 肉汤2推荐用于测试食品和临床材料中最常见的好氧和兼性厌氧细菌，用于抗微生物敏感性测试。该培养基具有良好的批次间重复性。磺胺、甲氧苄啶和四环素抑制剂的浓度较低，大部分非苛养性病原菌生长良好。酸水解酪蛋白和牛肉浸膏提供氨基酸和其它含氮物质、矿物质、维生素和碳，以维持微生物的生长。为了以粪肠球菌（Enterococcus faecalis）和磺胺甲唑-甲氧苄啶测定MIC值，氨基酸源中的胸腺嘧啶和胸苷含量必需特别低。淀粉中和了培养基中可能存在的有毒物质，并且对抗生素和微生物的生长有抑制作用。在高压蒸汽灭菌过程中，淀粉水解产生少量葡萄糖，葡萄糖是一种能量来源。添加钙和镁盐是为了调节培养基的离子浓度。
應用
阳离子调节的Mueller Hinton Broth 2 用于从临床标本中分离出的快速生长的需氧和兼性厌氧细菌的敏感性测试的定量程序。它已用于培养大肠杆菌、枯草芽孢杆菌、金黄色葡萄球菌和多西环素的连续稀释。
特點和優勢
NutriSelect® Plus 是粉末状培养基产品。
- 根据行业标准进行质量控制和生长促进测试。
- 符合 ISO 9001 标准的质量保证
- 高成本效益的粉末培养基
準備報告
将22 g悬浮于1000 ml蒸馏水中。必要时可加热使培养基完全溶解。分装，并在10-15lbs.压力下（115-121°C）高压蒸汽灭菌10分钟。不可过热。倒入前混匀。
注意：该培养基添加了适当的盐，以提供 20-25 mg/l 的钙和 10-12.5 mg/l 的镁，并且还需要针对性能参数进行调整。

While the infection rate of orthopedic implants is low, the required treatment, which can involve six weeks of antibiotic therapy and two additional surgical operations, is life threatening and expensive, and thus motivates the development of a one-stage re-implantation procedure.
Wall teichoic acid protects Staphylococcus aureus against antimicrobial fatty acids from human skin.

Skin-colonizing gram-positive bacteria produce wall teichoic acids (WTAs) or related glycopolymers for unclear reasons. Using a WTA-deficient Staphylococcus aureus mutant, we demonstrated that WTA confers resistance to antimicrobial fatty acids from human sebaceous glands by preventing fatty acid binding. Thus
