New antibiotic found in human noses
Voice of America - 08/14/2016
Kim Lewis directs the Antimicrobial Discovery Center at Northeastern University in Massachusetts. He wrote a commentary about the discovery in Nature Microbiology.
“So if you have lugdunin in your nose, chances are you are not going to be carrying staph aureus. So that was the initial finding of that study.”
Just like animals in the wild, bacteria in our bodies compete for survival. The bacterium Staphylococcus lugdunensis fights off S. aureus.
But it gets even more interesting. Scientists found that about one third of the population has S. aureus in their nose. But almost no one with the S. lugdunensisbacterium had any sign of the possibly harmful staph infection. A few people had neither bacterium in their noses.
