Chlorine Dioxide for the Prevention of Biomaterial-Associated Infections
****!!!!****!!!**** {301 pages} "Given the small percentage of viable spores that remained in the low humidity studies, increasing either the concentration of ClO2 or the exposure time could result in successful sterilization under these conditions" "Unlike ethylene oxide, sterilization with ClO2 can be achieved at ambient temperature and pressure. When at the same relative humidity and temperature (30°C), ClO2 is 1075 times more efficient" **** "results from the cytotoxicity experiments suggest that post-sterilization processing for materials sterilized with ClO2 is warranted. [to minimize residuals, etc]" "bacterial adhesion is the first step towards the development of infection" "[pg 245] possibilities explaining the difference in bacterial adhesion... including differences in the physicochemical properties of the material and the more rapid development of an accumulating substratum of bacteria (nonviable) on the surface" "the presence of proteins adsorbed to the material did not affect the bactericidal activity of the ClO2 produced by the material" "suggests... the influence of fibronectin, not necessarily on promoting bacterial adhesion, but maintaining it" "the presence of proteins adsorbed to the material did not affect the bactericidal activity of the ClO2" "presence of albumin and fibronectin did impact the viability of bacteria" "coating, such as a hydrogel (Changez et al. 2004) or a thin polymer film (Kwok et al. 1999a), could be used to control the release of ClO2 from the material, thereby extending the duration of bactericidal activity" "An alternative... would be the development of a delivery system that is activated by ultrasound" "a molecule that was affording it protection... While initial studies suggested that the molecule was extracellular, further investigation determined that it was not." "oxidization of GSH may serve as a protective mechanism for other more vital cell components" "An alternative hypothesis for the mechanism of resistance is that SP030724 is over expressing a transmembrane molecule that is either inactivating or inhibiting the bactericidal effects of ClO2."
