Nasal power

Scientists have discovered a bacteria living inside the human nose that produces an antibiotic capable of killing one of the most hard-to-treat pathogens, which causes serious, even deadly skin and wound infections, bloodstream infections and pneumonia. German researchers found this antibacterial substance was effective in treating skin infections in mice caused by Staphylococcus aureus bacteria, according to a study published in Nature. The scientists said the substance, which they named lugdunin, has potent antimicrobial effects against a range of bacteria, including antibiotic-resistant strains such as methicillin-resistant S. aureus (MRSA) and vancomycin-resistant Enterococcus bacteria.
