a type of virus that infects bacterial cells is called a
bacteriophage. A bacteriophage is a type of virus that infects bacteria. In fact, the word bacteriophage literally means bacteria eater, because bacteriophages destroy their host cells.All bacteriophages are composed of a nucleic acid molecule that is surrounded by a protein structure.ventually, new bacteriophages assemble and burst out of the bacterium in a process called lysis. Bacteriophages occasionally remove a portion of their host cells' bacterial DNA during the infection process and then transfer this DNA into the genome of new host cells. This process is known as transduction. A virus is a small parasite that cannot reproduce by itself. Once it infects a susceptible cell, however, a virus can direct the cell machinery to produce more viruses. Most viruses have either RNA or DNA as their genetic material. The nucleic acid may be single-or double-stranded.ome bacterial viruses (bacteriophages) may undergo lysogeny following infection of host cells. In this case, the viral genome is integrated into host-cell chromosomes, forming a prophage that is replicated along with the host genome. Viruses may infect any type of cell including animal cells, plant cells and bacterial cells. To view an example of the process of viral infection and virus replication, see Virus Replication: Bacteriophage.You will discover how a bacteriophage, a virus that infects bacteria, replicates after infecting a bacterial cell.iruses may infect any type of cell including animal cells, plant cells and bacterial cells. To view an example of the process of viral infection and virus replication, see Virus Replication: Bacteriophage. This association is called lysogeny, and the integrated phage DNA is referred to as a prophage (Figure 6-19). Under certain conditions, the prophage DNA is activated, leading to its excision from the host-cell chromosome and entrance into the lytic cycle. Bacterial viruses of this type are called temperate phages.ome bacterial viruses (bacteriophages) may undergo lysogeny following infection of host cells. In this case, the viral genome is integrated into host-cell chromosomes, forming a prophage that is replicated along with the host genome. Viruses that kill their infected host cell are called virulent. The DNA in these type of viruses reproduces through the lytic cycle. When these viruses reproduce, they break open, or lyse, their host cells, resulting in the destruction of the host. bacteriophage is a virus that infects bacteria. Bacteriophages, first discovered around 1915, have played a unique role in viral biology. The surface of viruses includes many copies of one type of protein that binds, or adsorbs, specifically to multiple copies of a receptor protein on a host cell. This interaction determines the host range of a virus and begins the infection process (Figure 6-15).ome bacterial viruses (bacteriophages) may undergo lysogeny following infection of host cells.

A bacteriophage is a virus that infects bacteria. Bacteriophages, first discovered around 1915, have played a unique role in viral biology. They are perhaps the best understood viruses, yet at the same time, their structure can be extraordinarily complex. bacteriophage is a virus that infects bacteria.

Bacteriophages, first discovered around 1915, have played a unique role in viral biology. A bacterial virus infects the cell by attaching fibers of its protein tail to a specific receptor site on the bacterial cell wall and then injecting the nucleic acid into the host, leaving the empty capsid outside.ithin the cell the virus nucleic acid uses the host machinery to make copies of the viral nucleic acid as well as enzymes needed by the virus and coats and enveloping proteins, the coat proteins of the virus.
