Bacteriophage

n. virus that causes infection in bacteria

This article is about a biological infectious particle; for other uses, see phage (disambiguation). A bacteriophage (from 'bacteria' and Greek phagein, 'to eat') is any one of a number of viruses that infect bacteria. The term is commonly used in its shortened form, phage.Typically, bacteriophages consist of an outer protein hull enclosing genetic material. The genetic material can be dsRNA, ssDNA, or dsDNA between 5 and 500 kilo base pairs long with either circular or linear arrangement. Bacteriophages are much smaller than the bacteria they destroy - usually between 20 and 200 nm in size.
