    Structural model at atomic resolution of bacteriophage T4 [1] The structure of a typical myovirus bacteriophage Anatomy and infection cycle of bacteriophage T4.. A bacteriophage (/ b æ k ˈ t ɪər i oʊ f eɪ dʒ /), also known informally as a phage (/ ˈ f eɪ dʒ /), is a virus that infects and replicates within bacteria and archaea.

    Bacteria, like plants, have strong cell walls that a virus must breach to infect the cell. Given that bacterial cell walls are much thinner than plant cell walls due to their much smaller size, some viruses have evolved mechanisms that inject their genome into the bacterial cell across the cell wall, while the viral capsid remains outside.

  4. Prophage - Wikipedia

    en.wikipedia.org/wiki/Prophage

    In the lytic cycle, the virus commandeers the cell's reproductive machinery. The cell may fill with new viruses until it lyses or bursts, or it may release the new viruses one at a time in an exocytotic process. The period from infection to lysis is termed the latent period. A virus following a lytic cycle is called a virulent virus.

  5. Escherichia virus T4 - Wikipedia

    en.wikipedia.org/wiki/Escherichia_virus_T4

    After the number of progeny phages reach a certain amount, they cause the host to lyse or break down, therefore they would be released and infect new host cells. [20] The process of host lyses and release is called the lytic cycle. Lytic cycle is a cycle of viral reproduction that involves the destruction of the infected cell and its membrane.

  6. Introduction to viruses - Wikipedia

    en.wikipedia.org/wiki/Introduction_to_viruses

    A special hormone called interferon is produced by the body when viruses are present, and this stops the viruses from reproducing by killing the infected cells and their close neighbours. Inside cells, there are enzymes that destroy the RNA of viruses. This is called RNA interference. Some blood cells engulf and destroy other virus-infected ...

  7. Lambda phage - Wikipedia

    en.wikipedia.org/wiki/Lambda_phage

    Multiplicity reactivation (MR) is the process by which multiple viral genomes, each containing inactivating genome damage, interact within an infected cell to form a viable viral genome. MR was originally discovered with phage T4, but was subsequently found in phage λ (as well as in numerous other bacterial and mammalian viruses [20]).

  8. Filamentous bacteriophage - Wikipedia

    en.wikipedia.org/wiki/Filamentous_bacteriophage

    Filamentous bacteriophages are a family of viruses (Inoviridae) that infect bacteria, or bacteriophages.They are named for their filamentous shape, a worm-like chain (long, thin, and flexible, reminiscent of a length of cooked spaghetti), about 6 nm in diameter and about 1000-2000 nm long.

  9. Virology - Wikipedia

    en.wikipedia.org/wiki/Virology

    Viruses are obligate intracellular parasites and because they only reproduce inside the living cells of a host these cells are needed to grow them in the laboratory. For viruses that infect animals (usually called "animal viruses") cells grown in laboratory cell cultures are used. In the past, fertile hens' eggs were used and the viruses were ...
