Bacteriophages: The Enemies of Bad Bacteria Are Our Friends!
Some bacteria can enter the human body and make people ill. Usually, these diseases can be cured by antibiotics, but sometimes bacteria are resistant to them. In these cases, bacteria become very dangerous. Bacteriophages are viruses that infect bacteria but are harmless to humans. To reproduce, they get into a bacterium, where they multiply and finally, they break the bacterial cell to release the new viruses. Therefore, bacteriophages kill bacteria. Here, we explain how bacteriophages can be used to treat infectious diseases or to remove bacteria from other places where they are undesirable.
