PDT Against Cutaneous Infection Ulcer

Recently, bacteria resistant to many antibiotics have spread and become a problem. Because using antibiotic causes to produce antibiotic-resistant bacteria, it is thought that it is necessary to develop new mean which is different from antibiotic, in order not to increase the number of resistant bacteria anymore. We focus on and study photodynamic therapy (PDT) as new treatment of bacteria infections. Here, we report effect of PDT against infection ulcer we have done so far. Key words： photodynamic therapy (PDT), 5-aminolevulinic acid (ALA), methicillin-resistant Staphylococcus aureus (MRSA), Pseudomonas aeruginosa
