The aim of this study was to determine and compare the antimicrobial activity of UV radiation of wavelength 253.7 nm (used in typical germicidal lamps) against Salmonella Enteritidis on the surfaces of conventionally produced white ceramic wall tiles (matt and shiny) and the same tiles coated with TiO₂, using three different methods: rf diode sputtering, atmospheric pressure chemical vapour deposition (APCVD), and spray pyrolysis deposition (SPD). Results clearly indicate that the bactericidal action of UV radiation is much stronger on the surfaces of tiles coated with TiO₂ than on the tiles uncovered. The strongest bactericidal effects of UV radiation was found for film prepared by APCVD, weaker for sputtering, and the weakest for SPD. Results of experiments for shiny and matt tiles did not differ statistically.
