It can tire the view through the screens where our eyes are permanently fixed. But do not throw a stone into a blue light, it could be a very effective weapon against top-of-the-line pigs that are today treated with antibiotics.
Working on the strain of one of the most known antibiotic-resistant bacteria, "Staphylococcus Aureus resistant to methicillin" (MRSA), scientists from West Lafayette University and Boston came to the aforementioned conclusions. in Advanced Science.
Explanation: S. aureus produces pigments that play a role in protecting the bacteria from attack. Particularly a gold pigment called Staphyloxanthin (STX) which protects against neutrophils, white blood cells are essential in the fight against pathogens.
Remove one of the bacterial defense
How to eliminate STX? Researchers have already tried to use antifungal drugs but without success. But scientists from West Lafayette and Boston found that if they beat MRSA with blue light, the STX membrane becomes more permeable, eliminating one of the bacterial defense: after the photo whitening becomes sensitive to even relatively mild antiseptics such as oxygen peroxide.
"This new tool can treat all the surface wounds infested with MRSA, which is usually very difficult to treat," says Pr-Seleem who participated in this paper.
However, human clinical studies are still needed to confirm the effectiveness of this practice using blue light. But it already looks like a new way of fighting without causing unwanted side effects, the most difficult to treat pathogens.
