A bacterial cell whose chromosome contains integrated bacteriophage DNA.
A bacterial cell whose chromosome contains integrated viral DNA.
a bacterium that possesses a repressed prophage as part of its genome
Bacterial cell or strain which carries a copy of a bacteriophage genome in its chromosome. Genes within the prophage will be expressed providing their promoters are active.
The combination of a bacterium and a temperate phage.
A lysogen or lysogenic phage is a phage that does not go into a lytic cycle but instead either integrates into the host bacteria's chromosome or "lives" as a stable plasmid within the host cell. In order to maintain the stability, the cI gene codes for repression of the lytic action, inhibiting the expression of genes that code for phage replication. Currently, a variety of studies are being conducted to see whether other genes are active during lysogeny.
