A total of 150 strains of staphylococci, clinically isolated, were tested for sensitivity to ovotransferrin (conalbumin). Among these, all the 50 coagulase-positive, mannitol-positive, and deoxyribonuclease-positive staphylococci appeared to be resistant to conalbumin, i.e., capable of growing in the presence of this transferrin. Among the other 100 strains, which were not classified as S. aureus, some appeared to be resistant and some were sensitive. The different behavior toward conalbumin is related to varying degrees of efficiency of the bacterial iron transport systems and, to test this, a simple method can be used, based on the addition of CrCl3 to the culture medium. The precipitation of iron produced by chromium salts has an effect on the growth of staphylococci similar to that produced by conalbumin and reveals the differences in the iron transport systems which occur in the genus Staphylococcus.
对临床分离出的150株葡萄球菌进行了对卵转铁蛋白（伴清蛋白）敏感性的检测。其中，所有50株凝固酶阳性、甘露醇阳性和脱氧核糖核酸酶阳性的葡萄球菌似乎对伴清蛋白具有抗性，即在这种转铁蛋白存在的情况下能够生长。在另外100株未归类为金黄色葡萄球菌的菌株中，有些表现出抗性，有些则敏感。对伴清蛋白的不同反应与细菌铁转运系统的不同效率程度有关，为了验证这一点，可以使用一种简单的方法，即在培养基中添加氯化铬。铬盐产生的铁沉淀对葡萄球菌生长的影响与伴清蛋白产生的影响相似，并揭示了葡萄球菌属中铁转运系统的差异。
