Even bacteria can get a virus! The viruses that infect bacteria are called bacteriophages, A bacteriophage is a type of virus that infects bacteria. In fact, the word “bacteriophage” literally means “bacteria eater,” because bacteriophages destroy their host cells.
Bacteriophages, just like other viruses, must infect a host cell in order to reproduce. The steps that make up the infection process are collectively called the lifecycle of the phage.
