Abstract
Stephanie F John Max R Derrick Alan E Jacob Pauline S Handley The combined effects of plasma and hydrogel coating on adhesion of Staphylococcus epidermidis and Staphylococcus aureus to polyurethane catheters FEMS Microbiology Letters Volume 144 Issue 23 November 1996 Pages 241–247 https//doiorg/101111/j157469681996tb08537xThe adhesion of three Staphylococcus epidermidis and three S aureus clinical isolates to uncoated and hydrogelcoated polyurethane catheters was tested following pretreatment of catheters with human plasma Plasma significantly decreased the adhesion of S epidermidis strains to uncoated polyurethane catheters but had no significant effect on the adhesion to hydrogelcoated catheters The influence of plasma on adhesion of S aureus strains to catheters was strain dependent Plasma significantly increased the adhesion of one strain SA6 to uncoated catheters For two other strains SA3 and SA14 plasma produced no clear effect on their adhesion to uncoated catheters adhesion values for each strain showed either a small but significant increase or a replicatedependent increase or decrease However plasma significantly increased the adhesion of all S aureus strains to hydrogelcoated polyurethane catheters Overall with the exception of one batch culture of S epidermidis strain SE3 tested attachment to plasmatreated hydrogelcoated catheters was statistically significantly lower by up to 85 than attachment to plasmatreated uncoated catheters for both S epidermidis and S aureus
