Material Detail

The image, Figure 12 from Harnessing the Power of Microbes as Therapeutics: Bugs as Drugs, depicts the lytic and lysogenic life cycles of bacteriophages as well as their connection. The attachment of phages inserts a plasmid into a bacterium which initiates one of the two life cycles: lytic or lysogenic. In a lytic cycle, the phage genome is transcribed, translated, and replicated to allow for new phages to be formed. One the new phages are fully assembled, the bacterium cell is lysed to allow the phages to infect another host. The lysogenic cycle occurs when the plasmid integrates into the bacterium's DNA and gets passed on to the daughter cells of the bacterium, effectively getting passed through generations. However, a certain event can cause the “dormant” phage within a generation to turn lytic and follow the lytic cycle.
