Exposure of Porphyromonas gingivalis to Red Light in the Presence of the Light-Activated Antimicrobial Agent Toluidine Blue Decreases Membrane Fluidity

Abstract

Porphyromonas gingivalis, one of the etiological agents of periodontitis, can be killed by red light in the presence of toluidine blue. The purpose of this study was to determine whether this light-induced killing was accompanied by changes in the fluidity of the organism's cytoplasmic membrane. A suspension of the organism was exposed to red light in the… (More)
