It is found that natural antibiotics in nasal cavity can kill ＂super bacteria＂

　　German researchers reported in the new authoritative academic journal Nature that they found a natural antibiotic in human nasal cavity, which can kill methicillin-resistant Staphylococcus aureus (MRSA), which is called "superbacteria" and is resistant to many antibiotics.

　　Researchers at the University of Tü bingen, Germany, found in the study of 187 hospitalized patients that a bacterium named Staphylococcus ludden rarely appeared with Staphylococcus aureus in the nasal cavity of patients. When the patient has Staphylococcus aureus in the nasal cavity, the rate of Staphylococcus aureus in the nasal cavity is only one sixth of that of the patient without Staphylococcus aureus in the nasal cavity. Further research shows that Staphylococcus ludden can produce a previously unknown natural antibiotic, which makes Staphylococcus aureus unable to survive in human nasal cavity. The researchers named it "Ludenin".

　　Animal experiments have shown that Luteinin can kill MRSA, vancomycin-resistant enterococci and other multi-resistant bacteria resistant to traditional antibiotics. For example, the ointment made of Ludwig successfully cured MRSA skin infection in mice, and Ludwig spray greatly reduced the number of MRSA in the nasal cavity of rats. The researchers say that antibiotics are usually produced only by bacteria and fungi in the soil, and it is a new discovery that human flora can also be a source of antibiotics. Next, they will focus on the application of ludenin, such as trying to implant ludenin-producing bacteria into high-risk patients to reduce the risk of MRSA infection.

　　Jim Lewis, a microbiologist at Northeastern University in the United States, said that this is the first time that scientists have made it clear that antibiotics produced by one bacterium can inhibit the existence of another bacterium in the same microbial community. Researchers believe that new discoveries will help to prevent and treat drug-resistant bacterial infections in the future, and also provide new ideas for finding new antibiotics in the future.
