Clostridium difficile Spore Inactivation Study Using Ultraviolet-C Energy
ثبت نشده
چکیده
METHOD: This study was carried out in a controlled laboratory environment setting. Clostridium difficile spores were placed in a laboratory room, in direct line of sight of the UV-C emitter device (the Emitter). This study only used definitive, preselected UV-C dose settings and was not based on treatment time or the distance the coupons were located from the Emitter. The dose delivered was measured by the System's remote UV-C sensor “challenge devices”. Independent tests were performed using six (6) different UV-C doses with three (3) coupons for each dose. After each controlled UV-C dose was delivered to each set of coupons the remaining viable Clostridium difficile spore colony counts were determined to compute the reduction from positive control coupons that were not irradiated.

Inactivation of Clostridium difficile spore outgrowth by synergistic effects of nisin and lysozyme.
Inactivating Clostridium difficile spores is difficult, as they are resistant to heat, chemicals, and antimicrobials. However, this note describes inactivation of C. difficile spore outgrowth by incubation in a solution containing a germinant (1% (m/v) sodium taurocholate), co-germinants (1% (m/v) tryptose and 1% (m/v) NaCl), and natural antimicrobials (20 nmol·L-1 nisin and 0.2 mmol·L-1 lysozy...
متن کاملAdherence of Clostridium difficile spores to Caco-2 cells in culture.
Clostridium difficile is the causative agent of the majority of antibiotic associated diarrhoea cases. C. difficile spores are recognized as the persistent and infectious morphotype as well as the vehicle of transmission of CDI. However, there is a lack of knowledge on how C. difficile spores interact with the host's epithelial surfaces. In this context, we have characterized the ability of C. ...

BACKGROUND Reusable bedpans and urinals are frequently cleaned and decontaminated using washer-disinfectors (WDs) that may be located in the central processing department (CPD) or on the ward. The objective of this study was to determine how efficiently the WDs provided cleaning and to evaluate the ability of such WDs to kill Clostridium difficile spores. METHODS The cleaning efficacy of 2 be...
متن کاملSynergistic efficacy of 405 nm light and chlorinated disinfectants for the enhanced decontamination of Clostridium difficile spores.
The ability of Clostridium difficile to form highly resilient spores which can survive in the environment for prolonged periods causes major contamination problems. Antimicrobial 405 nm light is being developed for environmental decontamination within hospitals, however further information relating to its sporicidal efficacy is required. This study aims to establish the efficacy of 405 nm light...
متن کاملProgesterone analogs influence germination of Clostridium sordellii and Clostridium difficile spores in vitro.
Clostridium sordellii and Clostridium difficile are closely related anaerobic Gram-positive, spore-forming human pathogens. C. sordellii and C. difficile form spores that are believed to be the infectious form of these bacteria. These spores return to toxin-producing vegetative cells upon binding to small molecule germinants. The endogenous compounds that regulate clostridial spore germination ...
