A new study published in the journal Nature Communications has revealed that a common skin bacterium has a previously unknown defense mechanism against other bacteria. This defense mechanism is known as a bacteriocin, and it could have important implications for treating skin infections. The bacteriocin was discovered in a bacterium called Propionibacterium acnes, which is found on the skin of humans and other animals. The researchers found that this bacteriocin helps the bacteria to defend itself against other bacteria that might compete for resources or damage the skin. This is an exciting discovery, as it could potentially be used in the development of new treatments for skin infections.
