Antibacterial photodynamic therapy mediated by 5-aminolevulinic acid on methicillin-resistant Staphylococcus aureus

The emergence of drug-resistant bacteria, such as methicillin-resistant Staphylococcus aureus (MRSA), has brought great difficulties to clinical treatment. Antibacterial photodynamic therapy (aPDT) is a new non-antibiotic treatment strategy for a variety of drug-resistant bacteria. However, there are few studies on the antimicrobial mechanism of a PDT mediated by 5-aminolevulinic acid (ALA-PDT) for MRSA. In this study, we observed the...
