A provirus is a virus genome that is integrated into the DNA of a host cell. In the case of bacterial viruses ( bacteriophages ), proviruses are often referred to as prophages . However, proviruses are distinctly different from prophages and these terms should not be used interchangeably.
A prophage is a bacteriophage (often shortened to "phage") genome that is integrated into the circular bacterial chromosome or exists as an extrachromosomal plasmid within the bacterial cell. [1] Integration of prophages into the bacterial host is the characteristic step of the lysogenic cycle of temperate phages.
Often simply called an antiviral. A class of antimicrobial medication used specifically for treating diseases caused by viral infections rather than ones caused by bacteria or other infectious agents. Unlike most antibiotics, antivirals typically do not destroy their target viruses but instead inhibit their development. They are distinct from virucides. assembly The construction of the virus ...
(A) When the host cell is only infected by a giant virus, the latter establishes a cytoplasmic virus factory to replicate and generates new virions, and the host cell is most likely lysed at the end of its replication cycle.
An endogenous viral element (EVE) is a DNA sequence derived from a virus, and present within the germline of a non-viral organism.EVEs may be entire viral genomes (), or fragments of viral genomes.
The human phageome is thought to be brought about in newborns through prophage induction of bacteria passed on from the mother vaginally during birth. [12] However, phages can be introduced through breastfeeding, made evident through studies finding near-exact matches of crAssphage sequences between mother and child. [ 12 ]
This int protein integrates the phage DNA into the host chromosome (see "Prophage Integration"). No Q results in no extension of the P R' promoter's reading frame, so no lytic or structural proteins are made. Elevated levels of int (much higher than that of xis) result in the insertion of the lambda genome into the hosts genome (see diagram).
The bacterial strain carrying the prophage is known as a lysogenic strain. [9] Lysogenization is strain-specific, so it allows for differentiation among different strains of bacteria within the same species. [10] The prophage may be chemically or physically induced to revert to the lytic pathway. [6]
