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.
