Antimicrobial activity of a novel peracetic acid disinfectants of Bioxy H on resistant pathogens

Purpose: The disinfection of the resistant pathogens in environment is critical in manipulation of infection control. The usually used disinfectant as chlorine may produce toxic by-products. The purpose of this study was to determine the antimicrobial activity of a novel PAA disinfectant (Bioxy H) on several resistant pathogens. It is a modified PAA, is less erosive damage and toxicity than traditional PAA but reserve the effective antibactericidal effect. Methods: We add the powder on sterile water to obtain the Bioxy H 5.0% (W/ V) solution. The resistant microorganisms were cultured twice and obtain the broth suspension of 0.5 McFarland. This was accomplished by performing a standard kill-time suspension test using a 2 minutes contact time. Negative and positive controls were performed. Results: The tested bacteria and Candida albicans were killed to zero in 2 minutes contact time.
