The number of all examined bacteria decreased together with time exposure of RCI. The lowest recovery was obtained, both from the rubber surface (6.36 log CFU × cm-2) and steel (6.04 log CFU × cm-2) in the case of Escherichia coli O157H7. On the other hand, Staphylococcus aureus was isolated in the largest number (rubber 7.88 log CFU × cm-2, steel 7.79 log CFU × cm-2). Among the tested environmental conditions, the greatest bacterial population was re-isolated at 4°C (distance 0.5 m, time 24 h), whereas the lowest population was found at a distance of 0.5 m (temperature 20°C, time 24 h) and on surfaces without contamination. In the samples treated with RCI, the bacterial population was the lowest on non-contaminated surfaces, ranging from 3.76 log CFU × cm-2 (E. coli O157H7) to 5.58 log CFU × cm-2 (S. aureus) for the rubber, ecka-Zacharska, Grudlewska, Kwiecińska-Piróg, Wiktorczyk, Kowalska, Paluszak, Kosek-Paszkowska, Brożek, Korkus and Gospodarek-Komkowska.Bacterial colonization and biofilm development on medical devices can lead to infection. Antimicrobial peptide-coated surfaces may prevent such infections. Melimine and Mel4 are chimeric cationic peptides showing broad-spectrum antimicrobial activity once attached to biomaterials and are highly biocompatible in animal models and have been tested in Phase I and II/III human clinical trials. These peptides were covalently attached to glass using an azidobenzoic acid linker. Peptide attachment was confirmed using X-ray photoelectron spectroscopy and amino acid analysis. Mel4 when bound to glass was able to adopt a more ordered structur
