Antimicrobial PDT for prosthetic joint infections
Motivation for the study Periprosthetic joint infections after hip and knee replacement surgeries are associated with high patient morbidity and a large financial cost. Challenging two-stage revision surgeries are required with long antibiotics regimes that can have limited efficacy and cannot eradicate drug-resistant strains like MRSA (methicillin-resistant Staphylococcus aureus). This study aims to investigate the

Novel antimicrobial phototherapy against emerging infectious diseases
Results PIAS-treated pathogens were effectively eradicated upon NIR illumination. The efficacy of PIAS was dependent on the NIR light dose, 50 J/cm2 eradicating all MRSA from the rat nasal tract (Figure 1). PIAS also saved all mice from fatal MRSA infections, similar to VCM+RFP antibiotics and even more effectively than VCM antibiotics
