Chemical & Biological Dynamics

Now in its thoroughly revised, updated Fifth Edition, this volume is a comprehensive, practical reference on contemporary methods of disinfection, sterilization, and preservation and their medical, surgical, and public health applications. More than a third of this edition's chapters cover subjects never addressed in previous editions. New topics covered include recently identified pathogens, microbial biofilms, use of antibiotics as antiseptics, synergism between chemical microbicides, pulsed-light sterilization of pharmaceuticals, and new methods for medical waste management.

The aim of this study was to develop a method for investigating the stability of the human NoV capsid in response to disinfectants and sanitisers (virucides) as an indirect method for determining virus infectivity. Capsid destruction or "virolysis" was measured using the reverse transcribed quantitative PCR (RT-QPCR) reaction in conjunction with RNase treatment (in order to destroy any exposed RNA). Two commercially available alcohol based handwashes, alcohols (75% (v/v) ethanol or isopropanol), quaternary ammonium compounds (0.14% BAC or 0.07% DIDAC), and chlorine dioxide (200 ppm) were all ineffective at promoting virolysis of human norovirus present in dilute clinical samples at the concentrations tested. GII.4 NoVs were sensitive to a combination of heat and alkali. These data show that NoVs present in dilute stool samples are resistant to virolysis using virucides that are used commonly.

{Testimony given before Congress for anthrax decontamination. CD History & level questions} "Improving computer resources are allowing investigators to simulate the transport processes within buildings. However little investigation on transport of reactive materials within the indoor environment has occurred. Furthermore, the analysis of such transport characteristics requires site specific model development. Ultimately it may be possible to develop empirical safety factors for the level of dosing based on building size and configuration, however a substantial experimental and modeling effort would be required to develop these relationships."

The synergistic effects of sequential treatments with chlorine dioxide (ClO2) and drying in killing Salmonella enterica on the surface of chicken eggshells were investigated. Initial experiments were focused on comparing lethalities of sodium hypochlorite (NaOCl) and ClO2. Eggs surface-inoculated wi …

The worldwide detection of pharmaceuticals and personal care products (PPCPs) in aquatic environment and drinking water has caused wide concern in recent years. The possibility for concurrent formation of N-nitrosodimethylamine (NDMA) during disinfection has become another significant concern for water quality. This study demonstrates that a group of PPCPs containing amine groups can serve as NDMA precursors during free chlorine or chlorine dioxide (ClO2) chlorination processes. Selected PPCPs after screening by NDMA yield were further investigated for NDMA formation conditions. High disinf...

Chlorine dioxide complex™ is a new molecule to dermatology that is a unique, non-toxic, broad spectrum anti-microbial and keratolytic compound. Chlorine dioxide has been used as an antiseptic in industrial settings for decades, primarily in water treatment facilities for municipal water supplies and food preparation. The compound has exceptional antiseptic properties with no known potential for development of resistance. It is a true keratolytic and anti-inflammatory, but is non-toxic to human tissue due to its unique mechanism of action. Chlorine dioxide’s use in consumer products was prev...
