A total of 100 strains of Proteus, clinically isolated, were tested for sensitivity to ovotransferrin and CrCl3. Only a minority of the tested strains were not capable of growing in the presence of these iron chelating substances. Significant differences in the resistance among the four species of Proteus were noticeable only by addition to the culture medium of CrCl3 5 mM. The fact that sensitive strains were capable of growing after addition of citrate to culture medium containing ovotransferrin or CrCl3 suggests the presence in the genus Proteus of a citrate-dependent iron transport system.
对临床分离出的100株变形杆菌进行了对卵转铁蛋白和氯化铬（CrCl3）敏感性的测试。只有少数受试菌株在这些铁螯合物质存在的情况下无法生长。仅在培养基中添加5 mM氯化铬（CrCl3）后，变形杆菌四种菌之间的耐药性才有显著差异。敏感菌株在向含有卵转铁蛋白或氯化铬（CrCl3）的培养基中添加柠檬酸盐后能够生长，这一事实表明变形杆菌属中存在一种依赖柠檬酸盐的铁转运系统。
