Controlling biofilm formation, prophage excision and cell death by rewiring global regulator H-NS of Escherichia coli. Microb. Biotechnol. 3, 344–356. doi: 10.1111/j.1751-7915.2010. ... Web28 aug. 2024 · The lytic cycle, or virulent infection, involves a virus taking control of a host cell and using it to produce its viral progeny, killing the host in the process. The lysogenic cycle, or non-virulent infection, involves the virus assimilating its genome with the host cell’s genome to achieve replication without killing the host. Figure 1.
Web5 mrt. 2024 · In the lysogenic cycle, phage DNA is incorporated into the host genome, forming a prophage, which is passed on to subsequent generations of cells. … Web16 aug. 2024 · The simplest way to identify the impact of these genes is to delete the entire prophage from the bacterial chromosome and search for phenotypes with the prophage-free derivative. 10,11,15 A bacterial strain can be cured of a prophage through induction using mitomycin C or ultraviolet light, 11,17,18 but this is a very time-consuming process, …
