Lytic cycle [virus] lysis period

The potent bacteriophage (virulent phage) infects the host cell and enters the lysis reaction, causing the host cell to Lysis. The entire process includes: adsorption, intrusion, shelling, biosynthesis, assembly and release. Lytic cycle, compared to lysogenic cyclethe lytic Cycle is one of the cycles viral of reproduction, the other being th e lysogenic cycle.   The lytic cycle results in the destruction of the infected cell and its membrane. Lysogenic cycle[virus] After some bacteriophages invade the parasitic cells, the gene is integrated with the bacterial genome, with the bacteria to replicate, and with the division of bacteria to the offspring, do not form viral particles, do not lysis bacteria. There are several different conditions for dissolving the source of dissolved lysogenization, one is that the bacterium of soluble phage infection makes it a soluble bacterium; First, in the process of dissolving, the host bacterial cells are infected with the bacteria, and then the bacteria are lysed and the proliferation of phage is synchronized with cell proliferation. What kind of reaction occurs depends on the genetic properties of the phage and host bacteria and the physiological conditions of the bacteria.
