Antibiotics are standard treatments for fighting dangerous bacterial infections. Yet the number of bacteria developing a resistance to antibiotics is increasing. Researchers from Texas A&M University and the University of São Paulo are overcoming this resistance with light.
The researchers tailored antimicrobial photodynamic therapy (aPDT)—a chemical reaction triggered by visible light—for use on antibiotic-resistant bacteria strains. Results showed the treatment weakened bacteria to where low doses of current antibiotics could effectively eliminate them.
“Using aPDT in combination with antibiotics creates a synergy of interaction working together for a solution,” said Vladislav Yakovlev, University Professor in the Department of Biomedical Engineering at Texas A&M and co-director of the project. “It’s a step in the right direction against resistant bacteria.”
