What does bacteriophage mean?

D’Hérelle coined the term bacteriophage, meaning “bacteria eater,” to describe the agent’s bacteriocidal ability. Bacteriophages also infect the single-celled prokaryotic organisms known as archaea. Thousands of varieties of phages exist, each of which may infect only one type or a few types of bacteria or archaea.

What is a bacteriophage used for?

Bacteriophages are used to control and eliminate bacterial contaminants from food surfaces and food-borne spoilage. Bacteriophages are highly specific, which makes them attractive for sanitization of ready-to-eat foods like milk, vegetables, and meat products.

What is a bacteriophage virus?

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. All bacteriophages are composed of a nucleic acid molecule that is surrounded by a protein structure.

How big is a bacteriophage?

They vary in size, and the size is correlated with the genome length (Lavigne et al. 2009 ). A very large known member is bacteriophage G of Bacillus megaterium, with a genome size of nearly 500 kb, several hundred genes, a head domain of 160 nm in diameter, and a tail over 450 nm long (Ageno et al. 1973 ).

What is an example of a bacteriophage?

For example, the proof that DNA was the molecule that transmitted genetic information, the basic mechanisms of gene regulation, and the genetic code, to name but a few, were all discovered using bacteriophages. Bacteriophages are drivers of bacterial evolution in the human microbiome (Level II evidence).
