説明

 Environmental cleaning and disinfection plays an important role as a part of the standard precautions to prevent healthcare-associated infections, whereas hand hygiene is one of the most important strategies for breaking the chain of transmission. Cleaning and disinfection of high-touch areas in a health-care facility is emphasized. And wiping with an alcohol-saturated cloth which has features such as low corrosion and a wide range of antimicrobial activity is performed commonly for this purpose. Although alcohol provides immediate activity against enveloped viruses, its virucidal activity against certain non-enveloped viruses, including norovirus, is insufficient. We created a novel alcohol-based hand rub, MR06B7, which is safe for the skin, and is active against an extended spectrum of microorganisms including non-enveloped viruses. For environmental surface disinfection, a novel disinfectant MR13B15, which is based on MR06B7, has been developed. In vitro antimicrobial activity against a variety of pathogens, material compatibility, and simulated surface disinfection and decontamination efficacy of MR13B15 were investigated. According to the results, MR13B15 demonstrated potent bactericidal, fungicidal, mycobactericidal, and virucidal activity within a short contact time in addition to superior efficacy against non-enveloped viruses compared to ethanol for disinfection. Moreover, MR13B15 showed better material compatibility. Two simulation tests conducted for evaluating the disinfection and decontamination potency on environmental surfaces against feline calicivirus, a surrogate for norovirus, indicated that MR13B15 had superior efficacy for surface treatment compared to ethanol. These findings suggest that MR13B15, which satisfies most requirements of an environmental surface disinfectant, may contribute to accomplishing advanced standard precautions in preventing infections.<br>
