Answer:
We have bacteria that live on us, and bacteria have bacterial viruses that live on them. These viruses are called bacteriophages . Viruses differ from bacteria in that they are not made of cells, but instead consist of a piece of DNA (or RNA) packed within a protein coat. A bacteriophage attaches itself to a susceptible bacterium and infects the host cell. Following infection, the bacteriophage hijacks the bacterium's cellular machinery to prevent it from producing bacterial components and instead forces them cell to produce viral components.
