d'Hérelle was a self-taught microbiologist. In 1917 he discovered that "an invisible antagonist", when added to bacteria on agar, would produce areas of dead bacteria. The antagonist, now known to be a bacteriophage, could pass through a Chamberland filter. He accurately diluted a suspension of these viruses and discovered that the highest ...
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.
He was allowed to store the research equipment at his home in Camberley. In 1949, Penguin Books published his chapter on the Discovery of the Bacteriophage alongside a chapter on the Bacteriophage by Felix d'Herelle in the popular series Science News. [18] Twort died on 30 March 1950.
The first human virus to be identified was the yellow fever virus. [6] In 1881, Carlos Finlay (1833–1915), a Cuban physician, first conducted and published research that indicated that mosquitoes were carrying the cause of yellow fever, [ 7 ] a theory proved in 1900 by commission headed by Walter Reed (1851–1902).
Phageome research in humans has largely focused on the gut, however it is also being investigated in other areas like the skin, [8] blood, [9] and mouth. [10] The composition of phages that make up a healthy human gut phageome is currently debated, since different methods of research can lead to different results. [ 11 ]
The phage group (sometimes called the American Phage Group) was an informal network of biologists centered on Max Delbrück that contributed heavily to bacterial genetics and the origins of molecular biology in the mid-20th century.
1944: The Avery–MacLeod–McCarty experiment isolates DNA as the genetic material (at that time called transforming principle). [24]1947: Salvador Luria discovers reactivation of irradiated phage, [25] stimulating numerous further studies of DNA repair processes in bacteriophage, [26] and other organisms, including humans.
CrAss-like phage (crassviruses) are a bacteriophage family representing the most abundant viruses in the human gut, discovered in 2014 by cross assembling reads in human fecal metagenomes. [1] In silico comparative genomics and taxonomic analysis have found that crAss-like phages represent a highly abundant and diverse family of viruses.
