Methylene Blue-Photodynamic Therapy Effectively Kills Antibiotic-Resistant Bacteria from Pediatric Patients with Perforated Appendicitis

This study shows that methylene blue-photodynamic therapy effectively kills antibiotic-resistant bacteria from pediatric perforated appendicitis patients, achieving over 99.9% bacterial kill in most strains.

Intra-Abdominal Photodynamic Therapy in a Rabbit Model of Perforated Appendicitis

This paper evaluates the feasibility and safety of laparoscopic methylene blue photodynamic therapy (MB-PDT) in a rabbit model of perforated appendicitis, showing no off-target injury and in vitro antimicrobial efficacy.

Susceptibility of bacterial species commonly found in abdominal abscesses to low-dose photodynamic therapy: Effects of methylene blue concentration, fluence rate, and fluence

This study evaluates the effectiveness of low-dose photodynamic therapy on four common abdominal abscess bacteria, finding that Gram-positive species are more susceptible than Gram-negative ones.
