Efficacy of a multi-purpose high level disinfection cabinet against Candida auris and other health care-associated pathogen

Published:December 23, 2019DOI:https://doi.org/10.1016/j.ajic.2019.11.029

      Highlights

      • Portable equipment is a source for pathogen dissemination.
      • We tested a high-level disinfection cabinet for small devices.
      • The technology disperses droplets of peracetic acid and hydrogen peroxide.
      • The disinfection cabinet was effective against multiple organisms
      • Candida auris was eliminated from inoculated equipment
      Portable equipment and other small devices used in health care are a potential source for dissemination of pathogens. We demonstrated that a high-level disinfection cabinet using ultrasonic submicron droplets of peracetic acid and hydrogen peroxide was effective against methicillin-resistant Staphylococcus aureus, Clostridiodes difficile spores, the nonenveloped virus bacteriophage MS2, and Candida auris on steel disk carriers. The device also eliminated Candida auris inoculated on real-world items of portable equipment.
