MRSA on surface: is it possible to control?

Methods This is a case control study, developed on a flowchart. Six sterile glasses surfaces (40x30cm) were contaminated with a suspension with 10 cfu/ml MRSA by spreading with a sterile spatula and left dry for 10 min. The efficacy of desinfections products were measure by imprinting rodac plates with Trypticase Soy Agar holding for 1min against the surface, before and after the desinfection procedure. The glass surface was divided in three parts and each part was cleaned three times. A sterile microfibre cloth (40x38cm) made by 10% polyester, 20% polypropylene and 70% viscose were folded three times, total sixteen sides, but using nine sides only; they were moistened with 50ml of 0.1% Peractic Acid or Etilic Alcohol 70% to clean three surfaces each. Furthermore, sterile gloves were used and had their imprints (both hands) made on rodac plates, holding for 15s. Plates were incubated at 37°C for 48h.
