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 ...
Like the two-hybrid system, phage display is used for the high-throughput screening of protein interactions.In the case of M13 filamentous phage display, the DNA encoding the protein or peptide of interest is ligated into the pIII or pVIII gene, encoding either the minor or major coat protein, respectively.
M13 is one of the Ff phages (fd and f1 are others), a member of the family filamentous bacteriophage ().Ff phages are composed of circular single-stranded DNA (), which in the case of the m13 phage is 6407 nucleotides long and is encapsulated in approximately 2700 copies of the major coat protein p8, and capped with about 5 copies each of four different minor coat proteins (p3 and p6 at one ...
Phage therapy, viral phage therapy, or phagotherapy is the therapeutic use of bacteriophages for the treatment of pathogenic bacterial infections. [ 1 ] [ 2 ] [ 3 ] This therapeutic approach emerged at the beginning of the 20th century but was progressively replaced by the use of antibiotics in most parts of the world after the Second World War .
Shadowed electron micrograph of unaligned phage. Ff phages (for F specific filamentous phages) is a group of almost identical filamentous phage (genus Inovirus) including phages f1, fd, M13 and ZJ/2, which infect bacteria bearing the F fertility factor.
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.
Filamentous phages retard bacterial growth but, contrasting with the lambda phage and the T7 phage, are not generally lytic. Helper phages are usually engineered to package less efficiently (via a defective phage origin of replication) [ 5 ] than the phagemid so that the resultant phage particles contain predominantly phagemid DNA.
CTXφ is generally present and integrated into the genome of the V. cholerae bacterium, and more rarely in a virion from outside the bacterium. While integrated into the bacterial genome, CTX prophages are found on each of the two chromosomes (in the O1 serogroup of V. cholerae) or arranged in tandem on the larger chromosome (in the El Tor biotype of V. cholerae).
