AsepticSure disinfection power outlined in peer reviewed paper
Medizone is in final production development of its AsepticSure decontamination systems
The American Journal of Infection Control has published a paper on the microbial kill-rates of AsepticSure - an ozone vapour-based fumigant achieving 6 log or more reductions for C. difficile, MRSA, VRE, E. coli and all other deadly bacterial pathogens tested.
The research paper, co-authored by Dr Dick Zoutman, Michael Shannon and Arkady Mandel, and published on 5 May, reveals how Medizone's AsepticSure system, using a proprietary ozone-based process, creates a highly reactive oxidative vapour with high-level antimicrobial properties across a broad array of infectious disease-causing pathogens.
The methodology outlined in the peer review article involves the blending of Medizone's patent pending combination of low dosage ozone gas with hydrogen peroxide vapour at specific relative humidity.
Full decontamination, i.e. 100% microbial kill-rates measured as minimal reduction rates ranging from 6 – 7.9 log, was achieved in all bacteria and spores tested on steel discs in a test chamber as well as on cotton fabric. The same degree of efficacy was repeated in Medizone's 81m3 full scale test room and then duplicated in a 90m3 hospital room.
Dr Shannon, president and director of Medical Affairs for Medizone said: "This synergistic effect was noted for all four vegetative bacteria we tested – MRSA, VRE, E. coli and P. aeruginosa – to the point where 100% decontamination levels were consistently achieved within 30 minutes of exposure.
"Bacterial kill-rates of this magnitude are unprecedented in relation to the relatively low concentration of ozone and short durations used. So too are the 100% kill-rates achieved with the spores of C. difficile and B. subtilis (the study surrogate for Anthrax) NB: 6 – 7 log reductions were attained under identical test conditions with only slightly longer exposure periods of 45 – 90 minutes respectively."
