Fig. 1 Cumulative percentage of graft fragments according to colony counts per fragment. Fragments were stratified according to the number of trapped bacteria per fragment, expressed as log10 colony forming units per square centimeter of graft material. Grafts were challenged with Staphylococcus aureus 209P-R after durations of graft function of 2 hours (○——○), 8 days ( ), 1 month (), 2 months (•-· -·•), 6 months (▵——▵).

Fig. 3 Scanning electron micrographs of Dacron graft implanted for 8 days and exposed to bacteremia for 2 hours. A, In areas with bare filaments one can observe clusters (arrow) of staphylococci (original magnification × 1000). B, Bacteria can also be observed almost individually (arrow) where flow surface is made of packed fibrin (original magnification × 1000).

Fig. 4 Scanning electron micrographs of Dacron graft implanted for 1 month and exposed to bacteremia for 2 hours. A, Bacterial clusters are visible only in areas with strands of fibrin (original magnification × 1300). B, Smooth and glistening areas do not retain any bacteria (original magnification × 1000).

Fig. 5 Scanning electron micrographs of Dacron graft implanted for 2 months and exposed to bacteremia for 2 hours. A, Numerous staphylococci are trapped in unorganized fibrin including in the vicinity of endothelial-like cells (arrow)(B). (A, original magnification × 1000; B, original magnification × 780.)
