Some researchers in Germany have found that Staphylococcus lugdunensis bacteria in the human nasal cavity are capable of producing lugdunin. It is a powerful antibiotic with a previously undiscovered chemical structure. This is a surprising development because normally antibiotics are formed only by soil bacteria and fungi. The findings of the research open up the possibility of finding other new and useful antibiotics in the human body. Tests on mice have shown that lugdunin can be used to combat pathogens that have become resistant to many traditional antibiotics. One potential use of this new type of antibiotic would be to introduce the harmless lugdunin-forming bacteria to patients who are at risk from MRSA, a bacterial infection. This new antibiotic may also be an effective tool to fight the growing problem of antibiotic resistance, caused by improper use of antibiotics. Lugdunin may save thousands of people’s lives as recent studies suggest that more people will die from resistant bacteria in the coming decades than from cancer.
