Fibronectin is more active than fibrin or fibrinogen in promoting staphylococcus aureus adherence to inserted intravascular catheters

Abstract

To further define the role of fibrin(ogen) and fibronectin in Staphylococcus aureus adherence to central venous catheters, the amount, chemical integrity, and biologic activity of these proteins adsorbed on lines inserted in hospitalized patients were prospectively studied. Polyurethane cannulas promoted a significantly lower adherence of S. aureus than polyvinyl chloride (P
