Black box of phage–bacterium interactions: exploring alternative phage infection strategies

Open Biology, 2021
The canonical lytic–lysogenic binary has been challenged in recent years, as more evidence has emerged on alternative bacteriophage infection strategies.

Lateral transduction is inherent to the life cycle of the archetypical Salmonella phage P22 [PDF]

, 2021
Lysogenic induction ends the stable association between a bacteriophage and its host, and the transition to the lytic cycle begins with early prophage excision followed by DNA replication and packaging (ERP). This temporal program is considered universal

Modelling the spatiotemporal complexity of interactions between pathogenic bacteria and a phage with a temperature-dependent life cycle switch

Scientific Reports, 2021
We apply mathematical modelling to explore bacteria-phage interaction mediated by condition-dependent lysogeny, where the type of the phage infection cycle (lytic or lysogenic) is determined by the ambient temperature. In a natural environment, daily and

Phage life cycles.

, 2019
Temperate phages can insert their genomes (in red) into the host bacterial chromosome (in blue) to become a prophage in the lysogenic life cycle. Following lysogenic induction, prophages excise and enter the lytic life cycle.

Genome sequence and characterization of Streptomyces phages Vanseggelen and Verabelle, representing two new species within the genus Camvirus

Scientific Reports, 2023
Despite the rising interest in bacteriophages, little is known about their infection cycle and lifestyle in a multicellular host. Even in the model system Streptomyces, only a small number of phages have been sequenced and well characterized so far. Here,

Molecular Modeling the Proteins from the exo-xis Region of Lambda and Shigatoxigenic Bacteriophages

Antibiotics, 2021
Despite decades of intensive research on bacteriophage lambda, a relatively uncharacterized region remains between the exo and xis genes. Collectively, exo-xis region genes are expressed during the earliest stages of the lytic developmental cycle and are

Photothermal‐Activated Antibacterial Amyloid‐Polyphenol‐Iron Hydrogels for Synergistic Wound Healing

Advanced Healthcare Materials, EarlyView.
We report a thermally triggered supramolecular hydrogel (LTFe) formed by Fe3+ and tannic acid on lysozyme amyloid fibrils. Fe3+ enables rapid gelation and photothermal transduction with an efficiency of 88.56%. The LTFe hydrogel exhibits excellent biocompatibility, potent antibacterial activity against E. coli and S.

Lytic and lysogenic infection of diverse Escherichia coli and Shigella strains with a verocytotoxigenic bacteriophage

, 2001
A verocytotoxigenic bacteriophage isolated from a strain of enterohemorrhagic Escherichia coli O157, into which a kanamycin resistance gene (aph3) had been inserted to inactivate the verocytotoxin gene (vt2), was used to infect Enterobacteriaceae strains.

Phages Powerpuff, Lego, and YesChef exhibit turbid bullseye plaque morphologies and are Siphoviridae.

, 2022
Purified phage lysates were plated using the double agar overlay method. Each phage exhibited 1–3 mm turbid bullseye plaques, suggestive of a lysogenic life cycle. The presence of long, flexible tails supported their classification as Siphoviridae.

CAMPYLOBACTER PHAGES: BIODIVERSITY AND APPLICATIONS [PDF]

Assiut Veterinary Medical Journal
Bacteriophages, or phages, are bacterial invading viruses and considered the biosphere's most prevalent biological agents. They reproduce either through a lytic cycle, leading to the lysis of bacterial cells, or a lysogenic cycle by integrating the phage
