bacteriophage [bak-te´re-o-fāj″] a virus that destroys bacteria by lysis; several varieties exist, and usually each attacks only one kind of bacteria. Certain types attach themselves to the cell membrane of the bacterium and instill a charge of DNA into the cytoplasm. DNA carries the genetic code of the virus, so that rapid multiplication of the virus takes place inside the bacterium. The growing viruses act as parasites, using the metabolism of the bacterial cell for growth and development. Eventually the bacterial cell bursts, releasing many more viruses capable of destroying similar bacteria. Called also bacterial virus. adj., adj bacteriopha´gic.
With some bacteria, notably those of the Streptococcus family, infection by certain phages can dramatically alter pathogenicity, converging previously innocuous microbes into deadly pathogenic strains. The so-called “flesh-eating” viruses are a striking example. They are relatively harmless bacteria until new geletic material is incorporated via a phage or plasmid.temperate bacteriophage one whose genetic material (prophage) becomes an intimate part of the bacterial genome, persisting and being reproduced through many cell division cycles; the affected bacterial cell is known as a bacterium" >lysogenic bacterium.bac·te·ri·o·phage (bak-tēr'ē-ō-fāj), Avoid the mispronunciation bak-te'rē-ō-fahzh. Avoid the misspelling and mispronunciation bacterialphage.A virus with specific affinity for bacteria. Bacteriophages have been found in association with nearly all groups of bacteria, including the Cyanobacteria; like other viruses they contain either (but never both) RNA or DNA and vary in structure from the seemingly simple filamentous bacterial virus to relatively complex forms with contractile "tails"; their relationships to the host bacteria are highly specific and, as in the case of temperate bacteriophage, may be genetically intimate. Bacteriophages are named after the bacterial species, group, or strain for which they are specific, for example, corynebacteriophage, coliphage; a number of families are recognized and have been assigned provisional names: Corticoviridae, Cystoviridae, Fuselloviridae, Inoviridae, Leviviridae, Lipothrixviridae, Microviridae, Myoviridae, Plasmaviridae, Podoviridae, Styloviridae, and Tectiviridae.
