Abstract
Bacterial adhesion on biomaterials is an important cause of associated infection. Many authors have studied the adhesion mechanisms of bacteria on biomaterials. These studies were useful in making materials more and more refractory to bacterial adhesion. We analysed the gas Chromatographie modifications of structural fatty acids of a Staphylococcus aureus strain after adhesion on two polymers, poly(methylmethacrylate) (PMMA), whose biological compatibility is known, and heparin-surface-modified PMMA (HSM-PMMA). We noted changes to the Chromatographie peaks peculiar to the fatty acids of S. aureus for each tested material and particularly for HSM-PMMA.
