This type of virus is a bacteriophage. It attacks bacteria. The T4 bacteriophage attacks E. coli.
Bacteriophage T4 virus
T4 bacteriophage is a DNA virus. It infects bacteria by injecting its DNA into the host cell and hijacking the cell's machinery to replicate its genetic material.
Bacteriophages ARE viruses that attack bacteria, making this question invalid. But if they meant to say "what bacteria does it attack?" then I would say T4 and E. Coli

Once the viral DNA is duplicated in the cell.
Bacteriophage viruses are nonliving. They are DNA or RNA encapsulated in a protein coated capsule with recognition sites to bind to specific target sites on bacteria and insert their genetic material for viral replication or to induce changes in the bacterial genetic material.
Once the T4 bacteriophage injects its genetic material into the host cell, infection becomes irreversible. This usually occurs as soon as the phage's tail fibers attach and the genome is injected, initiating the takeover of the host cell machinery for viral replication.
bacteriophage
In the lytic cycle of bacteriophage T4 infection, the viral DNA takes control of the host cell machinery to replicate and assemble new viruses, leading to cell lysis and release of viral particles. This process does not involve integration of the viral DNA into the host genome, which is a key characteristic of the lysogenic cycle.
Bacteriophage is the name given to a virus that infects bacteria. The name is frequently abbreviated to 'phage'. T4 phage is subject to a wide variety of experiments because it infects E. coli, and E. coli is one of the safer, more abundant and best understood bacteria to study.
The type of virus that infects a bacteria is called a bacteriophage. An example of such a bacteriophage is the T3 bacteriophage.
