金黄色葡萄球菌是一种致病细菌，需要铁来进行重要的代谢功能，导致疾病的。储层人类宿主内的铁是最丰富的血红素，这是血红蛋白的辅因子。为了获得铁血红蛋白，S.金黄色葡萄球菌利用一个复杂的系统，被称为铁规管表面的行列式（ISD）系统1。 ISD系统首次绑定主机血红蛋白的组成部分，然后提取并导入血红素，和，终于解放血红素铁在细菌胞浆2,3。通过这条途径已解剖众多的体外研究4-9。此外，ISD系统感染的贡献已被反复证明在小鼠模型中8,10-14。建立血红蛋白衍生的铁收购和增长的贡献ISD系统已被证明是更具挑战性的。生长测定血红蛋白作为唯一的铁源是复杂的by是不稳定市售血红蛋白，在生长培养基中的游离铁污染，并与铁螯合剂毒性。在这里，我们提出了一种方法，该方法克服了这些限制。从新鲜血液中制备高品质的血红蛋白，并储存于液氮中。纯化血红蛋白补充铁消耗介质模仿铁所遇到的脊椎动物宿主病原体内的恶劣环境。饥饿S.黄色葡萄球菌的最小操纵形式的血红蛋白诱导生长的方式，结合血红蛋白，提取血红素，通过血红素通过细菌的细胞壁，并降低在细胞质中的血红素的能力完全依赖于铁和补充。此法将有助于研究人员寻找阐明机制的hemoglobin-/heme-derived铁收购S.金黄色葡萄球菌和其他可能的细菌病原体。
