Background: The aim of this study was to investigate the decontamination capacity of 4 different types of cleaning cloths (microfiber cleaning cloth, cotton cloth, sponge cloth, and disposable paper towels) commonly used in hospital in their ability to reduce microbial loads from a surface used dry or wet in new condition. All of the cloths except disposable paper towels were also compared after 10 and 20 times of reprocessing, respectively, at 90 degrees C for 5 minutes in a washing machine.
Methods: Staphylococcus aureus (ATCC 6538) and Escherichia coli (ATCC 8739) were used as test organisms. Test organisms were then added to a test soil (6% bovine serum albumin and 0.6% sheep erythrocytes) resulting in a controlled concentration of 5 x 10(7) colony-forming units per milliliter in the final test suspension. Standardized tiles measuring 5 x 5 cm were used as test surface.
Results: Microfiber cloths showed the best results when being used in new condition. However, after multiple reprocessing, cotton cloth showed the best overall efficacy.
Conclusion: We therefore suggest that the choice of the cleaning utilities should be based on their decontamination efficacy after several reprocessings and recommend the establishment of strict and well-defined cleaning and disinfection protocols.

The peroxone reaction, a promising alternative technology for water treatment, is traditionally hampered by its restricted pH operational range and suboptimal oxidant utilization. In this study, we introduced a novel amphoteric metal oxide (ZnO)-regulated peroxone system that transcended the pH limitations of conventional peroxone processes. Our innovative approach exploited the unique properties of ZnO to regulate the reaction pathway of the traditional O/HO (or peroxymonosulfate, PMS) processes, resulting in a 52.

The COVID-19 pandemic has resulted in significant changes in our daily lives, including the widespread use of face masks. Face masks have been reported to reduce the transmission of viral infections by droplets; however, improper use and/or treatment of these masks can cause them to be contaminated, thereby reducing their efficacy. Moreover, regular replacement of face masks is essential to maintaining their effectiveness, which can be challenging in resource-limited healthcare settings.

Introduction: Positive pressure breathing-air-fed protective suits are used in biosafety level 4 (BSL-4) containment laboratories as personal protective equipment to protect workers from high-consequence pathogens. However, even with the use of primary containment devices, the exterior surfaces of these suits could potentially become contaminated with those pathogens and result in their inadvertent removal from containment. To address the risk of such pathogens escaping from containment via contaminated protective suits, these suits are decontaminated in a disinfectant chemical shower situated in an anteroom prior to exiting the BSL-4 laboratory.

Introduction: Cephalosporins can trigger hypersensitivity reactions in certain individuals. Consequently, strict regulations restrict the production of non-beta-lactam substances during or after cephalosporin manufacturing. Dry chlorine dioxide gas (dClO), together with ultra-performance liquid chromatography Mass spectrometry/mass spectrometry (UPLC-MS/MS) detection methods, has emerged as a promising method for decontaminating cephalosporin compounds.

This paper introduces a novel, compact plasma sterilization system, the Active Plasma Sterilizer (APS), for planetary protection space missions. The development of the APS system is done through iterative testing and design modifications aimed at addressing decontamination modalities for time and temperature, cleaning adhesive surfaces, and cleaning protocols beyond alcohol and bleach. Decontamination testing of Deinococcus radiodurans, Geobacillus stearothermophilus (spore forming bacteria), and Aspergillus fumigatus (fungi) was verified for the APS on relevant materials of 4 to 5 log reduction up to complete killing in 45 min or less.
