Cross-reactions between Staphylococcus epidermidis and 23 other bacterial species

F Espersen, J B Hertz, N Høiby


By quantitative immunoelectrophoretic methods, 43 antigens were found in a mixture of sonicated preparations of four Staphylococcus epidermidis strains, using corresponding rabbit antiserum. Two of the antigens were identified as cell wall teichoic acid and a peptidoglycan antigen, respectively. Using this antigen/antibody reference system, cross-reactions between S. epidermidis antigens and antigens from other bacterial species were investigated. Fourteen of the S. epidermidis antigens cross-reacted with antigens from all S. aureus strains investigated. Only few cross-reactions were found between S. epidermidis and bacteria not belonging to the Micrococcaceae. The antigenic relatedness, expressed as a matching coefficient, seems promising for taxonomic work.
