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.
Since bacteria become resistant against a single phage, d'Herelle suggested using "phage cocktails" containing different phage strains. Phage therapy soon became a boom, and a great hope in medicine. In 1924, 25 January, d'Hérelle received the honorary doctorate of the University of Leiden , [ 14 ] as well as the Leeuwenhoek medal , which is ...
Bacteriophage T7 (or the T7 phage) is a bacteriophage, a virus that infects bacteria. It infects most strains of Escherichia coli and relies on these hosts to propagate. Bacteriophage T7 has a lytic life cycle , meaning that it destroys the cell it infects.
Phage typing is based on the specific binding of phages to antigens and receptors on the surface of bacteria and the resulting bacterial lysis or lack thereof. [4] The binding process is known as adsorption. [5] Once a phage adsorbs to the surface of a bacteria, it may undergo either the lytic cycle or the lysogenic cycle. [6]
The phage group started around 1940, after Delbrück and Luria had met at a physics conference. Delbrück and Salvador Luria began a series of collaborative experiments on the patterns of infection for different strains of bacteria and bacteriophage. They soon established the "mutual exclusion principle" that an individual bacterium can only be ...
The total sequence length ranges from 7,826 (in phage pMC8) to 509,170 bp (in phage pHS181) with the GC content of these phage being an average of 38.25%. [6] Within Bacillus phage there are 12 clusters (A-L), 28 subclusters, and 14 singletons. Clusters are groups of related genomes with the 12 clusters showing at least 50% homology between ...
The two ends of the phage are capped by a few copies of proteins that are important for infection of the host bacteria, and also for assembly of nascent phage particles. These proteins are the products of phage genes 3 and 6 at one end of the phage, and phage genes 7 and 9 at the other end.
The coding region of the serine tRNA gene remains intact even after the phage integrates. The physical map of the T12 genome was found to be circular with a total length of 36.0kb. [9] The phage genome is reported to carry the speA gene, [12] which is a 1.7kb segment of the phage T12 genome flanked by SalI and HindIII sites. [8]
