A research team from the University of South Australia has developed a new way to eliminate antibiotic-resistant bacteria, based on therapeutic ingredients prepared using nanotechnology, and then activated by light.

The new treatment, which was announced (Sunday) on the university’s website, can eliminate antibiotic-resistant Staphylococcus aureus and Pseudomonas aeruginosa bacteria by 500,000-fold and 100,000-fold, respectively.

Staphylococcus aureus and Pseudomonas aeruginosa are among the most deadly germs in the world, and globally about 1.27 million people die as a result of these antibiotic-resistant bacteria.

“The new light therapy will be a game-changer for millions of people around the world,” says Mohamed Awad, the lead researcher on the study. “Staphylococcus aureus and Pseudomonas aeruginosa, both highly infectious bacteria, are commonly found on wounds, but if they get into the blood, It can lead to sepsis or death.” He adds: «Patients in hospitals, especially those with wounds or catheters, or those who use ventilators, have a higher risk of infection with these bacteria, and while antibiotics may help, their heavy use has led to waves of microbial resistance, which makes them ineffective. Often”. He explains, “Our photodynamic technology works differently, as it harnesses the energy of light to generate highly reactive oxygen molecules that destroy microbial cells and kill deadly bacteria, without harming human cells.”

The researchers tested antimicrobial photodynamic therapy on bacterial infections caused by antibiotic-resistant strains of Staphylococcus aureus and Pseudomonas aeruginosa.

“The technology has some major advantages over traditional antibiotics and other light treatments,” says Cliff Prestige, lead researcher. “The new nanotechnology treatment is created in an oil that is applied to the wound as a lotion, and when laser light is applied to the formulation, it creates forms of oxygen.” Interactive works as an alternative to traditional antibiotics ». He adds, “Current photoactive compounds also suffer from poor solubility in water, which means they have limited clinical application. The problem.
