Abstrakt: Photodynamic therapy (PDT) is an alternative treatment for infections that can kill drug resistant bacteria without damaging host-tissue. In this study we used bioluminescent methicillin-resistant Staphylococcus aureus, in a mouse skin abrasion model, to investigate the effect of PDT on bacterial inactivation and wound healing. RLP068/Cl, a tetracationic Zn(II)phthalocyanine derivative and toluidine blue (TBO) were used. The light-dose response of PDT to kill bacteria in vivo and the possible recurrence in the days post-treatment were monitored by real-time bioluminescence imaging, and wound healing by digital photography. The results showed PDT with RLP068/Cl (but not TBO) was able to kill bacteria, to inhibit bacterial re-growth after the treatment and to significantly accelerate the wound healing process (© 2013 WILEY-VCH Verlag GmbH & Co.
