Light-based therapy weakens antibiotic-resistant bacteria

Posted by in categories: biotech/medical, chemistry, engineering

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 (aPDT)—a chemical reaction triggered by visible light—for use on strains. Results showed the treatment weakened 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.”
