Abstract

The use of light-activated bactericidal agents—photobactericides—is suggested in local infection in order to conserve conventional antibacterials for more systemic disease. Local administration of a photobactericide such as methylene blue coupled with locally-targeted red light illumination ensures the production of non-specific reactive oxygen species and thus a rapid and localised antibacterial response, regardless of the conventional resistance status. To this end, the response of photobactericides to conventional resistance mechanisms, and their potential use in infection, is discussed.
Keywords: photobactericide; conventional resistance mechanisms; methylene blue photobactericide; conventional resistance mechanisms; methylene blue
