Insights into the mechanism of action of the arbitrium communication system in SPbeta phages

Nature Communications, 2022
The arbitrium system is a peptide-based communication system to coordinate the lysis-lysogenic cycle of phages infecting bacteria. Here Gallego del Sol et al. provide the crystal structure of Aim-receptor of Katmira phage infecting B.

A Protocol to Engineer Bacteriophages for Live-Cell Imaging of Bacterial Prophage Induction Inside Mammalian Cells

STAR Protocols, 2020
Summary: The gut microbiome is dominated by lysogens, bacteria that carry bacterial viruses (phages). Uncovering the function of phages in the microbiome and observing interactions between phages, bacteria, and mammalian cells in real time in specific ...

Novel Cluster AZ Arthrobacter phages Powerpuff, Lego, and YesChef exhibit close functional relationships with Microbacterium phages.

PLoS ONE, 2022
Bacteriophages exhibit a vast spectrum of relatedness and there is increasing evidence of close genomic relationships independent of host genus. The variability in phage similarity at the nucleotide, amino acid, and gene content levels confounds attempts

Repeated outbreaks drive the evolution of bacteriophage communication

eLife, 2021
Recently, a small-molecule communication mechanism was discovered in a range of Bacillus-infecting bacteriophages, which these temperate phages use to inform their lysis-lysogeny decision.

Early genome erosion and internal phage-symbiont-host interaction in the endosymbionts of a cold-seep tubeworm

iScience, 2023
Summary: Endosymbiosis with chemosynthetic Gammaproteobacteria is widely recognized as an adaptive mechanism of siboglinid tubeworms, yet evolution of these endosymbionts and their driving forces remain elusive.

Prophage Gifsy-1 Induction in Salmonella enterica Serovar Typhimurium Reduces Persister Cell Formation after Ciprofloxacin Exposure

Microbiology Spectrum, 2023
Persister cells are drug-tolerant bacteria capable of surviving antibiotic treatment despite the absence of heritable resistance mechanisms. It is generally thought that persister cells survive antibiotic exposure through the implementation of stress ...

Phage strategies facilitate bacterial coexistence under environmental variability [PDF]

PeerJ, 2021
Bacterial communities are often exposed to temporal variations in resource availability, which exceed bacterial generation times and thereby affect bacterial coexistence.

The role of bacteriophages in shaping bacterial composition and diversity in the human gut

Frontiers in Microbiology, 2023
The microbiota of the gut has continued to co-evolve alongside their human hosts conferring considerable health benefits including the production of nutrients, drug metabolism, modulation of the immune system, and playing an antagonistic role against ...

Calculating Biological Behaviors of Epigenetic States in Phage lambda Life Cycle [PDF]

, 2004
Gene regulatory network of lambda phage is one the best studied model systems in molecular biology. More 50 years of experimental study has provided a tremendous amount of data at all levels: physics, chemistry, DNA, protein, and function.
