  2. Virus latency - Wikipedia

    en.wikipedia.org/wiki/Virus_latency

    Virus latency (or viral latency) is the ability of a pathogenic virus to lie dormant within a cell, denoted as the lysogenic part of the viral life cycle. [1] A latent viral infection is a type of persistent viral infection which is distinguished from a chronic viral infection. Latency is the phase in certain viruses' life cycles in which ...

  3. Viral life cycle - Wikipedia

    en.wikipedia.org/wiki/Viral_life_cycle

    For the virus to reproduce and thereby establish infection, it must enter cells of the host organism and use those cells' materials. To enter the cells, proteins on the surface of the virus interact with proteins of the cell. Attachment, or adsorption, occurs between the viral particle and the host cell membrane.

  4. Viral replication - Wikipedia

    en.wikipedia.org/wiki/Viral_replication

    Viral replication is the formation of biological viruses during the infection process in the target host cells. Viruses must first get into the cell before viral replication can occur. Through the generation of abundant copies of its genome and packaging these copies, the virus continues infecting new hosts. Replication between viruses is ...

  5. Lytic cycle - Wikipedia

    en.wikipedia.org/wiki/Lytic_cycle

    In the lytic cycle, the viral DNA exists as a separate free floating molecule within the bacterial cell, and replicates separately from the host bacterial DNA, whereas in the lysogenic cycle, the viral DNA is integrated into the host genome. This is the key difference between the lytic and lysogenic cycles.

  6. Lysogenic cycle - Wikipedia

    en.wikipedia.org/wiki/Lysogenic_cycle

    The herpes virus can then exit this dormant stage and re-enter the lytic cycle, causing disease symptoms. Thus, while herpes viruses can enter both the lytic and lysogenic cycles, latency allows the virus to survive and evade detection by the immune system due to low viral gene expression. The model organism for studying lysogeny is the lambda ...

  7. Latent period (epidemiology) - Wikipedia

    en.wikipedia.org/wiki/Latent_period_(epidemiology)

    The period from the time of infection to the time of becoming infectious is called the pre-infectious period or the latent period. During the pre-infectious or latent period, a host may or may not show symptoms (i.e. the incubation period may or may not be over), but in both cases, the host is not capable of infecting other hosts i.e ...

  8. Viral transformation - Wikipedia

    en.wikipedia.org/wiki/Viral_transformation

    Viral transformation is the change in growth, phenotype, or indefinite reproduction of cells caused by the introduction of inheritable material. Through this process, a virus causes harmful transformations of an in vivo cell or cell culture .

  9. Introduction to viruses - Wikipedia

    en.wikipedia.org/wiki/Introduction_to_viruses

    Some viruses cause no apparent changes to the infected cell. Cells in which the virus is latent (inactive) show few signs of infection and often function normally. [43] This causes persistent infections and the virus is often dormant for many months or years. This is often the case with herpes viruses. [44] [45]
