Human Nose Holds Novel Antibiotic Effective Against Multiresistant Pathogens

(University of Tübingen) A potential lifesaver lies unrecognized in the human body: Scientists at the University of Tübingen and the German Center for Infection Research (DZIF) have discovered thatStaphylococcus lugdunensis which colonizes in the human nose produces a previously unknown antibiotic. As tests on mice have shown, the substance which has been named Lugdunin is able to combat multiresistant pathogens, where many classic antibiotics have become ineffective...
"Normally antibiotics are formed only by soil bacteria and fungi," says Professor Andreas Peschel. "The notion that human microflora may also be a source of antimicrobial agents is a new discovery." In future studies, scientists will examine whether Lugdunin could actually be used in therapy. One potential use is introducing harmless Lugdunin-forming bacteria to patients at risk from MRSA as a preventative measure.
