(60) Certain conditions can cause the dormant
prophage DNA to reactivate and initiate a lytic cycle.
coli have a tendency to activate a lysogenic SOS response in the Shiga
prophage and cause upregulation of the expression of Stx (29).
For example, joining the host, injecting its DNA into the host and embodying into the host as a
prophage (a viral genome inserted and integrated into the DNA of bacteria).
They are 99.9% similar at the genome sequence level, excluding one 70 kb
prophage carried by BR21 (Tables S1 and S2).
Furthermore, one of the hypothetical proteins (hp9) was similar to a Lactobacillus plantarum
prophage remnant LP4 protein [79].
Prophage sequences identified by PHAST constitute 5.8% of the bacterial chromosome, including seven intact, two incomplete, and one questionable
prophage (Table S2 and Figure S1).
Various physical and chemical stress factors cause
prophage induction in Nitrosospira multiformis 25196-an ammonia oxidizing bacteria.
It contains only one
prophage and one genomic island characterised by a mosaic structure composed of species-specific genes.
Latent forms of the viral genome are named "
prophage" [12].
Borneman et al., (5) the variation in the genomes of 14 strains examined for stress response can be explained by such factors as a
prophage (a bacterial virus incorporated into its DNA), regions involved with the utilization and transport of sugars and regions responsible for the biosynthesis of amino acids and cell wall components.
Bacterial cells lyse when a temperate bacteriophage infects a bacterial cell, whereas in lysogenization, bacteriophage DNA is integrated into the bacterial genome, resulting in a
prophage region in the bacterial genome.
