ly•so•gen•icˌlaɪ səˈdʒɛn ɪk(adj.)
harboring a temperate virus.
Ref: temperate (def. 5). 5
Origin of lysogenic:
ly•sog′e•ny-ˈsɒdʒ ə ni(n.)
the condition of a host bacterium that has incorporated a phage into its own genetic material
"when a phage infects a bacterium it can either destroy its host or be incorporated in the host genome in a state of lysogeny"
The incorporation of the nucleic acid of a bacteriophage into that of a host bacterium; sometimes transmitted to daughter cells following lysis
U.S. National Library of Medicine
The phenomenon by which a temperate phage incorporates itself into the DNA of a bacterial host, establishing a kind of symbiotic relation between PROPHAGE and bacterium which results in the perpetuation of the prophage in all the descendants of the bacterium. Upon induction (VIRUS ACTIVATION) by various agents, such as ultraviolet radiation, the phage is released, which then becomes virulent and lyses the bacterium.
Lysogeny, or the lysogenic cycle, is one of two methods of viral reproduction. Lysogeny is characterized by integration of the bacteriophage nucleic acid into the host bacterium's genome or formation of a circular replicon in the bacterium's cytoplasm. In this condition the bacterium continues to live and reproduce normally. The genetic material of the bacteriophage, called a prophage, can be transmitted to daughter cells at each subsequent cell division, and a later event can release it, causing proliferation of new phages via the lytic cycle. Lysogenic cycles can also occur in eukaryotes, although the method of DNA incorporation is not fully understood. The distinction between lysogenic and lytic cycles is that the spread of the viral DNA occurs through the usual prokaryotic reproduction, while the lytic phage is spread through the production of thousands of individual phages capable of surviving and infecting other cells. The key difference between the lytic cycle and the lysogenic cycle is that the lysogenic cycle does not lyse the host cell.
