Temperate phages can switch between a lytic and lysogenic life cycle. Lytic is more drastic, killing the host whereas lysogenic impacts host cells genetically or physiologically. [4] [5] [6] Here is a chart on temperate phages that are lytic and lysogenic and how they're related. Lysogeny is characterized by the integration of the phage genome ...
Structural model at atomic resolution of bacteriophage T4 [1] The structure of a typical myovirus bacteriophage Anatomy and infection cycle of bacteriophage T4.. A bacteriophage (/ b æ k ˈ t ɪər i oʊ f eɪ dʒ /), also known informally as a phage (/ ˈ f eɪ dʒ /), is a virus that infects and replicates within bacteria and archaea.
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.
Enterobacteria phage P4 (also known as satellite phage P4) is a temperate bacteriophage strain of species Escherichia virus P2 within genus Peduovirus (formerly P2-like viruses, P2virus, and P2likevirus), subfamily Peduovirinae, family Myoviridae. [1] It is a satellite virus, requiring P2-related helper phage to grow lytically.
The term was first used in an article by Modi et al. in 2013 [4] and has continued to be used in scientific articles that relate to bacteriophages and their metagenomes. A bacteriophage , or phage for short, is a virus that can infect bacteria and archaea, and can replicate inside of them.
Bacteriophage P2 is a temperate phage, which means that it can propagate lytically (i.e. directing the host cell to produce phage progenies and finally lysing the host when the phage progenies exit), as well as establish lysogeny (i.e. injecting and fusing its genetic material into the genome of the host without lysing the cell) and maintain as ...
P1 is a temperate bacteriophage that infects Escherichia coli and some other bacteria. When undergoing a lysogenic cycle the phage genome exists as a plasmid in the bacterium [1] unlike other phages (e.g. the lambda phage) that integrate into the host DNA. P1 has an icosahedral head containing the DNA attached to a contractile tail with six ...
Filamentous phage Cf1t from Xanthomonas campestris (of NCBI's proposed species Xanthomonas phage Cf1t, incertae sedis within Inoviridae, likely misspelled as Cflt), [24] was shown in 1987 to integrate into the host bacterial genome, and further such temperate filamentous phages have since been reported, many of which have been implicated in ...
