Novel MRSA-killing anibiotic from newly discovered nasal bacterium

The war against antibiotic-resistant bacteria continues to produce interesting new knowledge.  Antibiotic production by microbes has tended to be found in the fungus kingdom and amoungst soil bacteria which compete with each other. This group at University of Tubingen near Stuttgart report discovery of an antibiotic-producing Staphylococcus bacterium in human nasal passages, one of just a small handful of antibiotic-producing bacteria so far found in the human microflora – microorganisms the human body naturally hosts.  Best news is that the antibiotic this Staphylococcus bacterium produces – a cyclic peptide which the Tubingen group are calling lugdunin – is deadly to antibiotic-resistant MRSA.
