Examples of bacteriophage in the following topics:

  • Batch Culture of Bacteriophages

    • Bacteriophage cultures require host cells in which the virus or phage multiply.
    • For bacteriophages, cultures are grown by infecting bacterial cells .
    • A bacteriophage is any one of a number of viruses that infect bacteria .
    • This specificity means a bacteriophage can infect only those bacteria bearing receptors to which they can bind, which in turn determines the phage's host range.
    • For bacteriophages, cultures are grown by infecting bacterial cells.
  • The Lytic and Lysogenic Cycles of Bacteriophages

    • Bacteriophages, viruses that infect bacteria, may undergo a lytic or lysogenic cycle.
    • Bacteriophages are viruses that infect bacteria .
    • An example of a lytic bacteriophage is T4, which infects E. coli found in the human intestinal tract.
    • A temperate bacteriophage has both lytic and lysogenic cycles.
    • This transmission electron micrograph shows bacteriophages attached to a bacterial cell.
  • Mu: A Double-Stranded Transposable DNA Bacteriophage

    • Bacteriophage Mu is a temperate bacteriophage that uses DNA-based transposition in its lysogenic cycle.
    • Bacteriophage Mu, or phage Mu, is a temperate bacteriophage, a type of virus that infects bacteria.
    • Mu bacteriophage uses DNA-based transposition to integrate its genome into the genome of the host cell that it is infecting.

  • Overview of Bacterial Viruses

    • Bacteriophages are viruses that infect bacteria and are among the most common and diverse entities in the biosphere.
    • Bacteriophages (phages) are potentially the most numerous "organisms" on Earth.
    • Bacteriophages occur in over 140 bacterial or archaeal genera.
    • Over 5100 bacteriophages have been examined in the electron microscope since 1959.
    • Bacteriophages may have a lytic cycle or a lysogenic cycle, and a few viruses are capable of carrying out both.
  • RNA Bacteriophages

    • Nineteen families of bacteriophages that infect bacteria and archaea are currently recognized; of these, only two families have RNA genomes.
    • Nineteen families of bacteriophages that infect bacteria and archaea are currently recognized.
    • Cystoviruses are the only bacteriophage that are more closely related to viruses of eukaryotes than to other phage.
    • Bacteriophage Φ6 is a member of the Cystoviridae family.
    • Φ6 and its relatives have a lipid membrane around their nucleocapsid, a rare trait among bacteriophages.
  • Virulent Bacteriophages and T4

    • T-4 bacteriophage is a virulent bacteriophage that infects E. coli bacteria; virulent bacteriophages have a lytic life cycle.
    • Model organisms of virulent viruses that have been extensively studied include virus T4 and other T-even bacteriophages which infect Escherichia coli and a number of related Bacteria.
    • T-4 bacteriophage is a bacteriophage that infects E. coli bacteria.
    • These bacteriophage infect a host cell with their information and then blow up the host cell, thereby propagating themselves.
  • Scarlet Fever

    • Scarlet fever is caused by a bacteriophage that infects Streptococcus pyogenes.
    • Scarlet fever is caused by an erythrogenic toxin, a substance produced by the bacterium Streptococcus pyogenes (group A strep. ) when it is infected by a certain bacteriophage.
    • It is carried by the bacteriophage T12, which integrates into the Streptococcal genome, from where the toxin is transcribed.
  • Temperate Bacteriophages: Lambda and P1

    • In virology, temperate refers to the ability of some bacteriophages to display a lysogenic life cycle.
    • In virology, temperate refers to the ability of some bacteriophages (notable coliphage λ) to display a lysogenic life cycle.
    • P1 is a temperate bacteriophage (phage) that infects Escherichia coli and some other bacteria.
    • Enterobacteria phage λ (lambda phage, coliphage λ) is a bacterial virus, or bacteriophage, that infects the bacterial species Escherichia coli.
    • Schematic representation of the insertion of the bacteriophage lambda.
  • Complex and Asymmetrical Virus Particles

    • Some bacteriophages, such as Enterobacteria phage T4 , have a complex structure consisting of an icosahedral head bound to a helical tail, which may have a hexagonal base plate with protruding protein tail fibers.
    • Other archaeal viruses resemble the tailed bacteriophages, and can have multiple tail structures.
    • T4 is a bacteriophage that infects E. coli and is referred to as a complex virus.
  • Phage Display

    • A phage or bacteriophage is a virus capable of infecting a bacterial cell, and may cause lysis to its host cell.
    • Bacteriophages have a specific affinity for bacteria.
