摘要: The adherence of three clinical isolates Staphylococcus epidermidis to model polystyrene surfaces was studied in vitro using epifluorescent image analysis. A series 16 Pluronic surfactants (A-B-A block copolymers where is poly(ethylene oxide) (PEO) and B poly(propylene (PPO)) were used as surface modifiers for the surfaces. Substantial reductions (up 97%) bacterial adhesion levels achieved with all tested, irrespective PPO or PEO lengths. It appears likely that such treatments create a sterically stabilized adsorbed chains, conferring non-specific anti-adhesive properties which can limit attachment.
