Chemical produced by bacteria found in nose could help fight antibiotic-resistant super bugs

Scientists are continuously in search to find sources for chemical that could be harnessed to make drugs able to fight antibiotic-resistant super bugs. For quite some time, superbugs with highly resistance against antibiotic have caused tensions among scientists to explore more ways to device drugs that could be strong enough to deal with antibiotic resistance.

Most recently, some researchers at the University of Tübingen in Germany have found a source for chemicals that paves way for antibiotic resistance drugs. The source is none other than our nose. This certainly has left you suppressed, so did the researchers who led the finding. The findings were published in the journal Nature.

So far the largest and reliable source of useful bacteria for scientists has been soil. But now this source is turning insufficient as antibiotic resistance is on rise. The researchers of the study have discovered a bacterial species that is found in human nose. The bacteria are believed to produce a substance capable of killing variety of other bacteria, including the strain of drug-resistant Staphylococcus aureus known as MRSA.

S. aureus is found in noses of about 30% of humans and it often causes no harm. The researchers thought what had prevented 70% of human noses from having S. aureus. So they thought this could be because of some other bacteria that do not let S. aureus to spread. To confirm if it is the case, they studied 90 different human nasal bacteria and put them on individual battle with S. aureus in lab experiment.

They were right; it was another bacterium called Staphylococcus lugdunensis that prevented S. aureus growing. The researchers then studied S. lugdunensis to find a chemical that it produces to stop S. aureus. They came up with new antibiotic named lugdunin. They also found that lugdunin can treat S. aureus skin infections in mice and limit its spread in a rat's nose.
