- Abstract
Objectives: The aim of this study was to compare, in a blinded design, antifungal efficacy of two airborne disinfectants (AD) for Aspergillus-contaminated false ceilings of hospital rooms. Methods: Two types of ADs containing either hydroxyacetic acid (AD#1) or peracetic acid + H2O2 (AD#2) were tested for the disinfection of A. fumigatus on false ceiling of four hospital rooms. Airway disinfection involves non-directed spraying of disinfectants reaching all surfaces contained in a given volume. Results: A total of 11 different false ceiling tiles were sampled before and after disinfection in each of the four rooms tested. Product AD#2 showed a Contamination Rate (CR) of A. fumigatus decreasing from 7.2±6.5 colony-forming units (CFU)/m² (mean±SD) before to 2.5±3.4 after disinfection (adjusted p = 0.05). AD#1 had CR fall from 9.4±8.5 CFU/m² to 7.9±7.3 (adjusted p=0.80). Conclusions: AD#2 is significantly more effective at eradicating A. fumigatus, thus representing a good alternative to environmental management of this pathogen in hidden reservoirs.
