A type of virus that specifically infects and destroys bacteria.
Scientists are studying bacteriophages to find new ways to treat bacterial infections.
Bacteriophage is formed from "bacterium" (from Greek "bakterion", meaning rod or staff, referring to bacteria) and "phagein" (from Greek, meaning to eat). The word describes a virus that eats or infects bacteria.
Think of a virus that 'eats' ('phagein') bacteria ('bacterium') — that's what a bacteriophage does.
