Treating infections is one of the most widely known aspects of medical practice. Humans and other animals are in a constant and highly variable relationship with the microscopic world inside and outside our bodies. Bacteria help us digest and use our food, but they can also cause life-threatening infections. Dealing with the bad bugs often requires an antibiotic, a chemical that kills the bacteria. Finding new antibiotics that can be brought to the market as a safe, effective treatment is a long, expensive, arduous process. As a result, we don’t see too many new antibiotics.
Scientists have discovered a small molecule in the bloodstream of the giant panda that has antibacterial properties. The pandas make this small chain of amino acids (a peptide) naturally and it circulates in their body. Interestingly, it kills bacteria very quickly — more quickly than the drugs and molecules we already know about. The hope, of course, is that we can find a way to make this available to help humans and other animals. Scientists are working on making this peptide in the lab so that wild pandas can be protected.
This is another example of why research into the natural world is far, far more important than it might at first seem. Nature has a great deal to share with us about elegant solutions.
