Streptococcus gordonii invading host cells

The non-pathogenic non-invasive Streptococcus gordonii (red) is a common and harmless commensal bacterium of the oral human mucosa. By membrane-bound expression of the pathogenicity factor SfbI (Streptococci Fibronectin-binding Protein I) S. goordonii becomes an invasive bacterium.
