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 term is derived from Ancient Greek φαγεῖν (phagein) 'to devour' and bacteria .
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.
Bacteriophage Lambda Structure at Atomic Resolution [1] Enterobacteria phage λ (lambda phage, coliphage λ, officially Escherichia virus Lambda) is a bacterial virus, or bacteriophage, that infects the bacterial species Escherichia coli (E. coli). It was discovered by Esther Lederberg in 1950. [2]
This allows nitrogen, carbon, and phosphorus from the living cells to be converted into dissolved organic matter and detritus, contributing to the high rate of nutrient turnover in deep sea sediments. Because of the importance of deep sea sediments in biogeochemical cycles, marine bacteriophages influence the carbon, nitrogen and phosphorus cycles.
Phage "organismal" ecology is the most closely aligned of phage ecology disciplines with the classical molecular and molecular genetic analyses of bacteriophage. From the perspective of ecological subdisciplines , we can also consider phage behavioral ecology , functional ecology , and physiological ecology under the heading of phage ...
A culture of bacteria infected by bacteriophages, the "holes" are areas where the bacteria have been killed by the virus. The culture is 10cm in diameter. Phage typing is a phenotypic method that uses bacteriophages ("phages" for short) for detecting and identifying single strains of bacteria. [1]
Another important area of interest is the control of prophage gene expression with many of the lysogenic conversion genes (gene conversion) being tightly regulated. [15] This process is capable of converting non-pathogenic bacteria into pathogenic bacteria that can now produce harmful toxins [15] such as in staph infections. Since the specific ...
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 ...
