Bacteriophages, often called phages for short, are viruses that infect bacteria. They do this by latching onto bacteria and injecting their genetic material, essentially taking control of the bacteria. As a result, the infected bacteria are destroyed in the process. Bacteriophages play a significant role in controlling bacterial populations in nature and have potential uses in areas such as medicine, agriculture, and research. In contrast to antibiotics, phages can effectively destroy dangerous pathogens without harming useful bacteria in the environment in which they find themselves, as well as self-replicating to tackle all of the existing targets.
