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.
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 ...
Frederick William Twort FRS [1] (22 October 1877 – 20 March 1950) was an English bacteriologist and was the original discoverer in 1915 of bacteriophages (viruses that infect bacteria). [4]
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).
What he discovered was that when, after UV irradiation, two or more "dead" phage entered the same bacterial cell, they often became alive again and produced normal live progeny. [9] This was the first example of reactivation of cells or organisms that had been damaged by radiation.
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 ]
A number of “vampire viruses” have been discovered in soil samples in Maryland and Missouri for the first time.. The existence of the eerily-nicknamed viruses has been known to researchers for ...
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.
