Evaluating the Effects of Peracetic Acid and Chlorine Dioxide Disinfectants on Staphylococcus Aureus Isolated from Surfaces of NICU
Journal Title: Journal of Environmental Health and Sustainable Development - Year 2019, Vol 4, Issue 2
Abstract
Introduction: Today, disinfection of surfaces by using antimicrobial agents is critical for the prevention and control of pathogens and reduction of infection in hospital. The aim of this study was to investigate and compare the effects of two disinfectants against Staphylococcus aureus isolated from the NICU of Shahid Sadoughi Hospital of Yazd in 2017. Materials and Methods: In this descriptive cross sectional study, bacterial culture of samples collected from different surfaces of the NICU and S. aureus isolates were identified using conventional biochemical tests. Peracetic acid and chlorine dioxide various concentrations were used as disinfectants. Their effects against Staphylococcus aureus were determined by Standard disc diffusion method. Data were analyzed by linear mixed models in SPSS version 23. Results: 39.39% of samples were found to be S. aureus infected. The mean diameter of growth inhibition zone for peracetic acid 0.1% was significantly lower than that for peracetic acid 0.2%, and peracetic acid 0.1% was significantly higher than that for chlorine dioxide (P < 0.001). The comparison of growth inhibition zone diameters for peracetic acid 0.1% and chlorine dioxide disinfectants showed that the average diameter of the inhibition zone created by peracetic acid 0.1% was significantly higher than that created by chlorine dioxide. The most effective disinfectant on S. aureus strains isolated was peracetic acid 0.2% and the least effective disinfectant was chlorine dioxide. Conclusion: In health care facilities with S. aureus infection, peracetic acid 0.2% can be used effectively to reduce nosocomial infection rate.
