Difference Between Virulent and Temperate Phage

Virulent phages are restricted to lytic infections, where rapid viral replication ends in progeny release and bacterial death. Temperate phages can follow either a lytic or a lysogenic cycle. In the latter, viral DNA maintains itself in the host as a prophage.

What is the difference between a virulent phage and a temperate phage?

The key difference between virulent and temperate phage is that virulent phages kill bacteria during every infection cycle since they replicate only via the lytic cycle while temperate phages do not kill bacteria immediately after the infection since they replicate using both lytic and lysogenic cycles.

What is a virulent phage?

virulent phage A bacteriophage that causes the destruction of the host bacterium by lysis. Temperate phages, on the other hand, rarely cause lysis. A Dictionary of Plant Sciences.

What is meant by temperate phage?

noun, plural: temperate phages. A bacteriophage that displays lysogenic life cycle in contrast to virulent phage that does not have the ability to display lysogeny (especially following mutation). Supplement. Many temperate phages are capable of integrating their genome into the genome of their host.

What makes a temperate bacteriophage change into virulent virus?

Bacteriophages (phages for short) are viruses that infect bacteria and can be generally classified as virulent or temperate (for a review see [5]). ... Some stressful conditions (such as UV radiation or thymine starvation) may induce the production of the viral progeny and, as a consequence, the host cell lysis [6].

What is temperate virus?

viruses, particularly bacteriophages, are called temperate (or latent) because the infection does not immediately result in cell death. The viral genetic material remains dormant or is actually integrated into the genome of the host cell.

What is lambda phage DNA?

Lambda DNA, a linear, double-stranded phage DNA containing 12 bp single-stranded complementary 5'-ends, is derived from an Escherichia coli bacteriophage (Bacteriophage lambda cI₈₅₇ Sam7). Lambda DNA can also be used as a substrate in restriction enzyme activity assays. ...

What are the two types of phages?

There are two types of bacteriophages: those that are virulent and those that are temperate. Virulent bacteriophages kill their host bacterial cell by causing it to go through lysis, or burst. T-phages are examples of virulent phages.

What's a prophage?

: an intracellular form of a bacteriophage in which it is harmless to the host, is usually integrated into the hereditary material of the host, and reproduces when the host does.

What is virulent disease?

A virulent disease is one that's infectious, spreading, and making lots of people sick, while a virulent rant is just a verbal attack, causing sickness of the emotional kind. Either way, something virulent puts a strain on the people who get it.

Is Temperada a lambda phage?

It was discovered by Esther Lederberg in 1950. The wild type of this virus has a temperate life cycle that allows it to either reside within the genome of its host through lysogeny or enter into a lytic phase, during which it kills and lyses the cell to produce offspring.

What does a temperate phage do?

In virology, temperate refers to the ability of some bacteriophages (notably coliphage λ) to display a lysogenic life cycle. Many (but not all) temperate phages can integrate their genomes into their host bacterium's chromosome, together becoming a lysogen as the phage genome becomes a prophage.

What is a phage conversion?

a change in one or more phenotypic characteristics of a host bacterium as a result of infection by a BACTERIOPHAGE, normally a TEMPERATE PHAGE. When the phage lysogenizes the host expression of these genes can confer new properties on the cell. ...
