In recent years, antibiotics are used a lot. Because of this, many types of bacteria have become resistant to antibiotics. This is why it becomes harder and harder to get rid of bacterial infections. To discover new antibiotics, we must return to nature. The proof for this comes from the research of a microbiologist at the University of Tubingen in Germany. They have investigated bacteria living in the nose of a human.
Just like on the rest of the body, there are multiple types of bacteria living in the nose. The focus is placed on the Staphylococcus aureus (S. aureuss) bacteria, which generally is not harmful. However, in some cases, it can happen that the bacteria are harmful. The researchers wanted another bacterium from the same family, namely S. lugdunesis, this was added to the artificial nose in the lab environment. What was found is that the added bacterium got rid of the S. aureuss bacteria. This same experiment was carried out in an (artificial) open wound. This also showed that the bacterium S. lugdunesis ensured that the S. aureuss bacterium was eliminated.
The research also showed that the conditions in the nose are far from optimal for bacteria, for example, there is little food for them. However, the bacteria seem happy to be in the nose. As a result of these findings, it is very likely that different bacteria can be found in other places in the body, that can act as an antibiotic.
This form of antibiotics carries risks with it. Actually, all types of antibiotics can cause resistance. Everything can cause the bacteria to get more protection across generations. In addition, the use of other bacteria to get rid of a certain bacterium is risky. In the above example, the S. lugdunesis bacterium is known to have symptoms that include infections of the heart, joints, and skin. However, there are also known bacteria that constitute less danger, and possibly could be used as antibiotics.
