Scientists in the United States have developed a vital tool in the battle against superbugs by re-engineering a decades-old antibiotic.
A modified version of the antibiotic vancomycin is believed to be much more effective at fighting Enterococci bacteria, which is found in hospitals and can cause dangerous wound and blood infections. The drug, which has been used for 60 years, is described as an antibiotic of last resort, used only after treatment with other antibiotics has failed. But some infections have become resistant even to vancomycin in its current form.
