Scientists say they have found a way to make a powerful antibiotic effective again against superbugs that had learned to resist it. The antibiotic, vancomycin, is used to treat serious infections. Over time, some dangerous bacteria became resistant. Instead of creating a new drug, researchers combined vancomycin with a small molecule called pghi-4. This molecule blocks a bacterial enzyme that helps the bacteria resist the antibiotic. In lab tests, the combination killed drug-resistant strains of E. faecium, a type of bacteria that can cause severe infections in hospitals. The study raises hope that similar molecules could help rescue other antibiotics that are losing their power. Antibiotic resistance is a growing global health problem, making common infections harder to treat. The approach of pairing old drugs with helpers could be a faster and cheaper way to fight superbugs. More research is needed to see if the combination works in humans.
