1. They may have a lytic cycle or a lysogenic cycle. 2. There are two main types of virus infection : lysogenic . 3. Upon infection, P22 can enter either a lytic or lysogenic growth pathway. 4. It shows a lytic cycle and a lysogenic cycle. 5. "Mannheimia phage phiMhaA1-PHL101 " is a lysogenic phage. 6. For example, study of bacteriaphage lambda shows us a lysogenic virus determines lysis or lysogeny. 7. In the lysogenic cycle, the phage DNA first integrates into the bacterial chromosome to produce the prophage. 8. When the F-was lysogenic for ?, lysogeny was mapped to the " gal " locus. 9. However, under certain conditions, the phage DNA may integrate itself into the host cell chromosome in the lysogenic pathway. 10. The disease results from virus particles in a single sensory ganglion switching from their latent lysogenic cycles to their active lytic cycles.
