Abstract:
In the present study, we tried to investigate immunoreactivity of iron-repressible cell wall proteins and exoproteins of Staphylococcus aureus when the convalescent serum obtained from the patient with septicemia was applied. On SDS-PAGE and western blot analysis, several iron-repressible cell wall proteins expressed in iron-deficient BHI showed strong immunoreactivity, whereas no or relatively weak immunoreactivity was shown in iron-sufficient BHI. Several exoproteins were expressed only in iron-deficient BHI and these exoproteins showed strong immunoreactivity. These results indicate that several iron-repressible cell wall proteins and exoproteins are expressed and are immunogenic in vivo. Since in vivo state is an relatively iron-restricted condition, we recommend the use of iron-deficient media for studies concerning pathogenicity of staphylococcal in human.
