The Antigenic Composition of Streptococcus Faecalis Associated with Ineffective Endocarditis

Abstract

The composition of the cell wall of Streptococcus faecalis was examined for the presence of specialised structures or components responsible for attachment to host endocardial tissue in infective endocarditis (IE). Analysis of cells by sodium dodecylsulphate-polyacrylamide gel electrophoresis (SDS-PAGE), crossed immunoelectrophoresis (CIE) and immunoblotting revealed that the protein and antigenic profiles of cells grown in complex laboratory medium were different to those of cells grown in conditions approximating to the in vivo environment. The antigenic pattern of S. faecalis was more complex after growth in brain-heart infusion than after growth in serum. Growth in serum resulted in expression of three major protein antigens, 73, 40 and 37K, which were characteristic of S. faecalis species and were absent from other streptococcal species and Staphylococcus aureus...
