The latent form of a bacteriophage in which the viral genes are incorporated into the bacterial chromosomes without causing disruption of the bacterial cell.

[Short for French probactériophage : Greek pro-, before; see pro-2 + French bactériophage, bacteriophage (bacterio- + Greek -phagos, -phage).]

(Microbiology) a virus that exists in a bacterial cell and undergoes division with its host without destroying it. Compare bacteriophage
[C20: by contraction from French probactériophage; see pro-2, bacteriophage]

a stable, inherited form of bacteriophage in which the genetic material of the virus is integrated into, replicated, and expressed with the genetic material of the bacterial host.
