Fixed points and limit cycles in the population dynamics of lysogenic viruses and their hosts [PDF]

open access: green, 2010
Starting with stochastic rate equations for the fundamental interactions between microbes and their viruses, we derive a mean field theory for the population dynamics of microbe-virus systems, including the effects of lysogeny. In the absence of lysogeny,

The Life Cycle Transitions of Temperate Phages: Regulating Factors and Potential Ecological Implications

open access: yesViruses, 2022
Phages are viruses that infect bacteria. They affect various microbe-mediated processes that drive biogeochemical cycling on a global scale. Their influence depends on whether the infection is lysogenic or lytic.

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

open access: yesNature 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.

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

open access: yesPLoS 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

open access: yeseLife, 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.

Phage strategies facilitate bacterial coexistence under environmental variability [PDF]

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

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

open access: yesMicrobiology 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 ...

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

open access: yesFrontiers 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]

open access: yes, 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.

Genomic characterization of bacteriophage BI-EHEC infecting strains of Enterohemorrhagic Escherichia coli

open access: yesBMC Research Notes, 2021
Objective The aims of this research were to determine the genomic properties of BI-EHEC to control Enterohemorrhagic Escherichia coli (EHEC), which was isolated from previous study.
