Lysogeny Health Dictionary

Lysogeny: From 1 Different Sources


n. an interaction between a *bacteriophage and its host in which a latent form of the phage (prophage) exists within the bacterial cell, which is not destroyed. Under certain conditions (e.g. irradiation of the bacterium) the phage can develop into an active form, which reproduces itself and eventually destroys the bacterial cell.

Bacteriophage

(phage) n. a virus that attacks bacteria. In general, a phage consists of a head, tail, and tail fibres, all composed of protein molecules, and a core of DNA. The tail and tail fibres are responsible for attachment to the bacterial surface and for injection of the DNA core into the host cell. The phage grows and replicates in the bacterial cell, which is eventually destroyed with the release of new phages. Each phage acts specifically against a particular species of bacterium. This is utilized in phage typing, a technique of identifying bacteria by the action of known phages on them. See also lysogeny.... bacteriophage
