Popular Science: A NEW NATURAL ANTIBIOTIC HAS BEEN DISCOVERED IN THE HUMAN NOSE
Scientists ID’d the new antibiotic after swabbing people’s noses and culturing the different strains of bacteria they found. Among their menagerie were both MRSA (which lives in about 30 percent of people’s noses) and another bacterium (Staphylococcus lugdunensis) that killed it when the two were introduced. Its weapon, the team discovered, was lugdunin, which is the first member of a new class of antibiotics.
