Abstract:
:The comparative adherence of seven strains of Staphylococcus epidermidis to plastic surfaces was measured by an agar overlay technique in which adherent organisms were counted by their ability to form colonies under an agar overlay. The degree of adherence to plastics decreased in the order polystyrene, polyvinyl chloride, Silastic, and polytetrafluoroethylene.
