TRANSCRIPT

Scientists searching for new medicines have found an antibiotic in an unusual place, the human nose. The compound produced by nose-dwelling microbes can kill several dangerous pathogens. Here is James Gauha. Inside of our bodies there's a microscopic war taking place between thousands of species of bacteria competing for food and space. The research studied how some species keep their rivals obey and discovered that a nostril-dwelling bacterium, Staphylococcus lugdunensis, was producing an antibiotic. Tests published in the journal, Nature, showed the drug could kill superbugs including MRSA. New antibiotics are desperately needed as doctors are struggling with the growing threat of untreatable infections. The last new class of the drugs to reach patients was developed decades ago. The study shows that our own bodies may be a rich source of new drugs.
