title: Environmental contamination by multidrug-resistant microorganisms after daily cleaning.
abstract: We analyzed 91 samples of high-touch surfaces obtained within the first hour after daily cleaning in intensive care unit rooms occupied with patients with multidrug-resistant organisms (MDROs). We determined that 22% of high-touch surfaces in rooms with methicillin-resistant Staphylococcus aureus patients and 5% of high-touch surfaces in rooms with multiresistant Pseudomonas aeruginosa patients were colonized with the same strain as the patient. We postulated that textile cleaning wipes could be contaminated with MDROs and may contribute to its spreading within the room.
