Coating of a surface with 2-methacryloyloxyethyl phosphorylcholine (MPC) co-polymer significantly reduces retention of human pathogenic microorganisms

FEMS Microbiol Lett. 2005 Jul 1;248(1):37-45. doi: 10.1016/j.femsle.2005.05.019.

Abstract

The present study compares the retention of four species that are often isolated in association with biomedical device-related infections - Staphylococcus aureus, Streptococcus mutans, Pseudomonas aeruginosa, and Candida albicans - to three different surfaces. All four bacterial species were found to bind significantly less well to MPC-coated surfaces than to non-coated surfaces. We attribute this effect to the "superhydrophilicity" of MPC-coated surfaces, whereas hydrophobic surfaces are well known to reduce bacterial retention and thus to inhibit a crucial step in the formation of bacterial biofilms that lead to biomedical device-related infections and complications.
