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.
Methylene blue is used in aquaculture and by tropical fish hobbyists as a treatment for fungal infections. It can also be effective in treating fish infected with ich, the parasitic protozoa Ichthyophthirius multifiliis. It is usually used to protect newly laid fish eggs from being infected by fungus or bacteria.
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.

T7 has a life cycle of 17 min at 37˚C, i.e. the time from infection to the lysis of the host cell when new phages are released. Due to the short latent period, most physiological studies are conducted at 30˚C where infected cells lyse after 30 min. However, high-fitness strains of T7 have been isolated with a latent period of only ~11 min at ...
The bacteria are infected with phages and die, producing new phages; the medium clears. The medium is filtered through porcelain filter, holding back bacteria and larger objects; only the smaller phages pass through. In early 1919, d'Hérelle isolated phages from chicken feces, successfully treating a plague of chicken typhoid with them. [13]
A corynebacteriophage (or just corynephage) is a DNA-containing bacteriophage specific for bacteria of genus Corynebacterium as its host. [1] Corynebacterium diphtheriae virus [2] strain Corynebacterium diphtheriae phage [2] (aka Corynephage β [3] or just β-phage [4] [5]) introduces toxigenicity into strains of Corynebacterium diphtheriae as it encodes diphtheria toxin, [6] [7] [8] [5] [4 ...
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 ...
