Adherence of methicillin-resistant Staphylococcus aureus isolates causing persistent bacteremia (PB; black bars) and those causing resolving bacteremia (RB; white bars) to fibrinogen, fibronectin, platelets, and endothelial cells. Fibrinogen, fibronectin, and platelet binding values represent comparisons of the entire strain set cohort; endothelial cell binding represents comparison of the 2 strains used for in vivo analyses. Data represent findings from at least 2 independent assays performed on different days. *P < .05, compared with RB isolates.
