Scientists Find New Antibiotic Right under Our Noses

Previously, antibiotics were discovered by analyzing soil samples. But this time scientists in Germany wants to discover antibiotic from bacteria that is already present in human body.

They found bacteria known as Staphylococcus aureus in almost 30 percent of people. A Staphylococcus aureus is a bacteria that is responsible for growing health problems.

Scientists unveiled another in-nose bacterium called Staphylococcus lugdunensis appears to be keeping the rival staph at bay in some people by producing its own antibiotic. To treat such bacterial infections, scientists have found new antibiotic called lugdunin.

They tested it on mice who was affected by Staphylococcus aureus. At last, they found that this antibiotic could effectively clear the bacteria. Scientists got great success in finding lugdunin against bacteria.

Still, staph doesn’t seem to be able to adapt to lugdunin.

Andreas Peschel, a microbiologist at the University of Tuebingen, said, “For whatever reason, it seems to be very, very difficult for Staphylococcus aureus to become resistant to lugdunin, which is interesting.”

Other scientists think Lugdunin is not safe treatment because it shows likely that this antibiotic could be as toxic for cells. Still, this approach could become as inspiration for further antibiotic discoveries.

Peschel doesn’t believe that this antibiotic is harmful too. He said, “This is just a beginning. Even if the new antibiotic turns out not to be suitable it might be possible to adapt the bacterium or transfer key genes to innocuous germs that could then be used to fight Staphylococcus aureus.”
