Effectiveness of antibacterial clothes and wall material against methicillin resistant Staphylococcus aureus and Pseudomonas aeruginosa

Abstract

To evaluate the antibacterial activities of antibacterial clothes and wall material, we measured the reduction rates of MRSA and P. aeruginosa using four products of antibacterial clothes and one wall material. Antibacterial activities are judged by the reduction rates of bacteria after 18 hours incubation at 35.0 degrees C. In the 50 strains of MRSA tested, two of four brands of clothes showed over 99% reduction rates, while only one brand showed a reduction rates over 99% in the 13 strains of P. aeruginosa. The wall material tested showed a reduction rates over 99% for the 50 strains of MRSA and over 90% for the 50 strains of P. aeruginosa. These data indicate that usage of some products of antibacterial clothes and wall material in the hospital may be useful the prevention of nosocomial infection.
