Abstract

The ferric enterobactin receptor protein (81 kDal) of O111 was purified by preparative sodium dodecyl sulphate-polyacrylamide gel electrophoresis and used to raise polyclonal antiserum in rabbits. This antiserum was used in conjunction with the immunoblot technique to examine the degree of antigenic homology of the ferric enterobactin receptor protein among 17 pathogenic and laboratory strains of Both the molecular weight and the antigenic properties of the enterobactin receptor were highly conserved. However, the laboratory strain C and a pathogenic enteroinvasive strain, O164, were unusual in not producing the 81 kDal protein. The antiserum also recognized an 81 kDal protein from iron-restricted and an 83 kDal protein from iron-restricted
