The proposed study demonstrated the efficacy of innovative non-antibiotic strategies including Methylglyoxal (MGO), Light-Emitting Diode (LED) and Complex Magnetic Fields (CMFs) against interkingdom biofilms composed by Staphylococcus aureus, Pseudomonas aeruginosa and Candida albicans using the Lubbock chronic wound biofilm model. Researchers tested Methylglyoxal (MGO), the active antimicrobial compound from Manuka honey, red LED phototherapy (630 nm) and Complex Magnetic Fields (CMFs) both individually and in combination.
The results demonstrated that MGO, LED and CMFs, applied alone or in combination, significantly reduced microbial viability. More importantly, combination treatment enhanced antibiofilm activity compared to single treatments, as demonstrated by biofilm disaggregation and reduced microbial viability confirmed by advanced microscopy analyses, underling the CMFs capability to inhibit Candida hyphal formation.
This work highlights the potential of eco-sustainable and non-invasive combined approaches to effectively disrupt polymicrobial biofilms and supports their future development as alternative therapeutic strategies for chronic wound management.
