Bacteriophage - Wikipedia
A bacteriophage (/ bækˈtɪərioʊfeɪdʒ /), also known informally as a phage (/ ˈfeɪdʒ /), is a virus that infects and replicates within bacteria and archaea. The term is derived from Ancient Greek φαγεῖν (phagein) 'to devour' and bacteria.
Bacteriophages - StatPearls - NCBI Bookshelf
Sep 26, 2022 · Bacteriophages, also known as phages, are viruses that infect and replicate only in bacterial cells. They are ubiquitous in the environment and recognized as the earth's most abundant biological agent. They are extremely diverse in …
Phages in nature - PMC
In this article we describe the roles of phages in different host systems and show how modeling, microscopy, isolation, genomic and metagenomic based approaches have come together to provide unparalleled insights into these small but vital constituents of the microbial world.
Bacteriophage | Definition, Life Cycle, & Research | Britannica
Nov 29, 2024 · Bacteriophage, any of a group of viruses that infect bacteria. Bacteriophages were discovered independently by Frederick W. Twort in Great Britain (1915) and Felix d’Herelle in France (1917). Thousands of varieties of phages exist. Certain types serve key roles in …
The Biotechnological Application of Bacteriophages: What to Do …
Bacteriophages are viruses that selectively target and infect bacteria and offer various advantages over conventional antibiotics, including host-specific infections, self-amplification, coevolution, and adaptability [1, 2].
Bacteriophages and their Genomes - PMC - PubMed Central (PMC)
Bacteriophages offer a special perspective on the diversity, origins, and evolution of viruses, not only in their tremendous abundance – there are more than 10 31 phage particles in the biosphere – but in their distant origins, likely more than three billion years ago [1, 2].
Bacteriophage: Structure, Replication, Uses • Microbe Online
Bacteriophages “bacteria-eater” are infectious agents that replicate as obligate intracellular parasites in bacteria with high selectivity. They are the powerful regulators of bacterial populations in natural ecosystems and are found in the soils, plants, rivers, and …
Bacteriophages: Structure, Life Cycles, and Their Applications
Oct 7, 2024 · Bacteriophages, often referred to as phages, exhibit a fascinating structural complexity that underpins their ability to infect bacterial cells. At the core of their architecture is the nucleic acid, which can be either DNA or RNA, encapsulated within a protective protein shell known as the capsid.
Phage therapy: From biological mechanisms to future directions
Increasing antimicrobial resistance rates have revitalized bacteriophage (phage) research, the natural predators of bacteria discovered over 100 years ago. In order to use phages therapeutically, they should (1) preferably be lytic, (2) kill the bacterial host efficiently, and (3) be fully characterized to exclude side effects.
