A brand new examine evaluated a low-cost but efficient approach to fight bacterial resistance utilizing curcumin–the pure yellow plant compound in turmeric.
In 2017, a tragic dying in a Nevada hospital was linked to a brand new pressure of micro organism that had developed a resistance to 26 totally different antibiotics. Referred to as ‘superbugs’, such antibiotic-resistant micro organism (together with MRSA) stays a urgent public well being risk.
Now researchers at Texas A&M College have proven that curcumin, the compound that provides turmeric its attribute shiny yellow coloration, can be utilized to cut back this antibiotic resistance.
They confirmed that when curcumin is deliberately given to micro organism as meals, after which activated by mild, it may set off deleterious reactions inside these microbes, finally killing them. They demonstrated that this course of reduces the variety of antibiotic-resistant strains and renders typical antibiotics efficient once more.
The outcomes of the examine had been printed this week within the journal Scientific Reviews.
“We need alternative ways to either kill the superbugs or find a novel way to modify natural processes within the bacteria so that antibiotics start to act again,” stated Dr. Vanderlei Bagnato, professor within the Division of Biomedical Engineering and senior writer on the examine.
Photodynamic inactivation, a method that has proven promise in combating bacterial resistance, makes use of mild and light-sensitive molecules, known as photosensitizers, to supply reactive oxygen species that may kill microorganisms by disrupting their metabolic processes.
Within the new experiments, the staff used curcumin, which can also be a pure meals for micro organism. They examined this method on strains of Staphylococcus aureus (MRSA) which can be immune to amoxicillin, erythromycin, and gentamicin.
The researchers uncovered the micro organism to many cycles of sunshine publicity after which in contrast the minimal focus of antibiotics wanted to kill the micro organism after mild publicity versus people who didn’t get mild publicity.
“When we have a mixed population of bacteria where some are resistant, we can use photodynamic inactivation to narrow the bacterial distribution, leaving behind strains that are more or less similar in their response to antibiotics,” Bagnato informed Texas A&M Information.
“It’s much easier now to predict the precise antibiotic dose needed to remove the infection.”

The staff famous that photodynamic inactivation utilizing curcumin has great potential as an adjuvant or further remedy with antibiotics for illnesses, like pneumonia, attributable to antibiotic-resistant micro organism.
“Photodynamic inactivation offers a cost-effective treatment option, which is crucial for reducing medical expenses not only in developing countries but also in the United States,” stated Dr. Vladislav Yakovlev, professor within the Division of Biomedical Engineering and writer on the examine. “It also has potential applications in military medicine, where this technology could be used to treat battlefield wounds and prevent the development and spread of antimicrobial resistance, a significant concern in combat situations.”
