Prions pose a challenge to decontamination, particularly before the re-use of surgical instruments. They have relatively high resistance to standard decontamination methods and require extreme chemical and/or heat-based treatments for devices used in known or suspected cases of disease. This study investigated the effectiveness of a new gaseous hydrogen peroxide sterilisation process for prions...

(...) Here we report the findings of a multicenter in vitro study performed to assess the antimicrobial activity of 400-nm blue light against bacteria in both planktonic and biofilm growth modes. Blue light was tested against a panel of 34 bacterial isolates (clinical and type strains) (...) All planktonic-phase bacteria were susceptible to blue light treatment, with the majority (71%) demonstr...

The technological potential of non-thermal plasmas for the antimicrobial treatment of heat sensitive materials is well known and has been documented in a great number of research activities, but the realisation of industrial plasma-based decontamination processes remains a great challenge. One of the reasons for this situation is the fact that an antimicrobial treatment process needs to conside...

Pathogenic contamination of beef has prompted consumer fear and concern around the globe. It has threatened trade and economic profit and has stimulated ideas for developing new control measures to enhance product safety in beef processes. Even though the beef industry has utilized technologies such as steam pasteurization, and organic acid rinses in carcass decontamination, there is a need for...

Several antimicrobial compounds have been used in commercial meat processing plants for decontamination of pathogens on beef carcasses, but there are many commercially available, novel antimicrobial compounds that may be more effective and suitable for use in beef processing pathogen-reduction programs. Sixty-four prerigor beef flanks (cutaneous trunci) were used in a study to determine whether...

BACKGROUND The aim of the present systematic review and meta-analysis was to assess the efficacy of antimicrobial photodynamic therapy (aPDT) as a therapeutic protocol for oral decontamination. METHODS In order to address the focused question: Is aPDT a useful therapeutic protocol for oral decontamination?, an electronic search without time or language restrictions was conducted up to July 20...

Photodynamic therapy (PDT) is presented as a promising antimicrobial therapy that can eliminate microorganisms present in endodontic infections. This treatment is based on the use of a nontoxic photosensitizing agent followed by irradiation of a resonant light source being capable of generating highly reactive species that are harmful to microorganisms. The purpose of this paper is to review th...
