Phage therapy is the use of bacteriophages to treat bacterial infections. Bacteriophage treatment offers a possible alternative to conventional antibiotic treatments for bacterial infection. [55] It is conceivable that, although bacteria can develop resistance to phages, the resistance might be easier to overcome than resistance to antibiotics.
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.
The tubular tail has helical symmetry and is 16-20 nm in diameter. It consists of a central tube, a contractile sheath, a collar, a base plate, six tail pins and six long fibers. It is similar to Tectiviridae, but differs in the fact that a myovirus' tail is permanent. Contractions of the tail require ATP. On contraction of the sheath, sheath ...
Mycobacteriophage Bxb1 Structure [1]. A mycobacteriophage is a member of a group of bacteriophages known to have mycobacteria as host bacterial species. While originally isolated from the bacterial species Mycobacterium smegmatis and Mycobacterium tuberculosis, [2] the causative agent of tuberculosis, more than 4,200 mycobacteriophage species have since been isolated from various environmental ...
The species was formerly named T-even bacteriophage, a name which also encompasses, among other strains (or isolates), Enterobacteria phage T2, Enterobacteria phage T4 and Enterobacteria phage T6. Use in research
The tubules consist of repeating units of the proteins TssA and TssB (VipA/VipB) arranged as a sheath around a tube built from stacked hexameric rings of the haemolysin co-regulated protein (Hcp). [ 12 ] [ 13 ] At the tip of the Hcp tube sits a trimer of the phage tail spike-like protein VgrG, which is in turn capped by a pointed PAAR domain ...
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 ...
The RM system was first discovered by Salvatore Luria and Mary Human in 1952 and 1953. [1] [2] They found that a bacteriophage growing within an infected bacterium could be modified, so that upon their release and re-infection of a related bacterium the bacteriophage's growth is restricted (inhibited; also described by Luria in his autobiography on pages 45 and 99 in 1984).
