EDTA as a potential agent preventing formation of Staphylococcus epidermidis biofilm on polichloride vinyl biomaterials.

Polichloride vinyl (PCV) is a widely used thermoplastic polymer, also in the production of medical devices. In the present study we assess the influence of EDTA in vitro on the biofilm structure formed by Staphylococcus epidermidis isolates on PCV biomaterials (Nelaton and Thorax catheters). The 6 strains of S.
