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.

Jan 14, 2019 · It uses viruses to treat bacterial infections. Bacterial viruses are called phages or bacteriophages. They only attack bacteria; phages are harmless to people, animals, and plants.

4 days ago · A bacteriophage is 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 laboratory research.

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.

Feb 17, 2025 · Bacteriophages (phages) are viruses that selectively target and kill bacteria. They are the most abundant commonly occurring natural entities, playing crucial roles in regulating bacterial populations and influencing microbial ecosystems. Phages are useful as they can destroy bacteria resistant to drugs such as antibiotics.

Unraveling the biology of phages and their relationship with their hosts is key to understanding microbial systems and their exploitation. 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 ...

Apr 8, 2025 · PHORCE is a new high-throughput method that enables precise measurement of lytic phage amplification rates in bacterial populations. Using PHORCE, this study reveals broad phenotypic diversity among E. coli and P. aeruginosa phages and shows that phage-antibiotic interactions are primarily determined by the antibiotic.

Nov 9, 2015 · Viruses that infect bacteria (bacteriophages; also known as phages) were discovered 100 years ago. Since then, phage research has transformed fundamental and translational biosciences.

Feb 3, 2020 · In this Review, we explore phage diversity at the structural, genomic and community levels as well as the complex evolutionary relationships between phages, moulded by the mosaicity of their...

Phages are the obligate parasite of bacteria and have complex interactions with their hosts. Phages can live in, modify, and shape bacterial communities by bringing about changes in their abundance, diversity, physiology, and virulence.
