Novel Erwinia persicina Infecting Phage Midgardsormr38 Within the Context of Temperate Erwinia Phages

open access: yesFrontiers in Microbiology, 2020
Prophages or prophage remnants are found in chromosomes of many bacterial strains and might increase the environmental fitness and/or virulence of their hosts.

Epigenetics as a first exit problem

open access: yes, 2001
We develop a framework to discuss stability of epigenetic states as first exit problems in dynamical systems with noise. We consider in particular the stability of the lysogenic state of the lambda prophage, which is known to exhibit exceptionally large ...

Exponential sensitivity of noise-driven switching in genetic networks [PDF]

open access: yes, 2008
Cells are known to utilize biochemical noise to probabilistically switch between distinct gene expression states. We demonstrate that such noise-driven switching is dominated by tails of probability distributions and is therefore exponentially sensitive ...

Bacterial Diversification in the Light of the Interactions with Phages: The Genetic Symbionts and Their Role in Ecological Speciation

open access: yesFrontiers in Ecology and Evolution, 2018
Phages have a major impact on microbial populations. In this work, we discuss how predation, transduction, lysogeny, and phage domestication lead to symbio-centric genomic interactions between bacteria and phages, ranging from antagonistic to mutualistic.

Biochemical Studies of Lysogeny

open access: yesJournal of Biological Chemistry, 1960
SUMMARY 1. The physical characteristics of X virus obtained from ultra- violet induction of Escherichia coli K12X have been compared with those of X virus obtained by infection of the sensitive host E. coli W-1485. No significant differences were observed, and it has been concluded that the present evidence supports the view that the X virus from ...

Lysogen stability is determined by the frequency of activity bursts from the fate‐determining gene

open access: yesMolecular Systems Biology, 2010
The ability of living cells to maintain an inheritable memory of their gene‐expression state is key to cellular differentiation. Bacterial lysogeny serves as a simple paradigm for long‐term cellular memory.

Temporal Dynamics of Soil Virus and Bacterial Populations in Agricultural and Early Plant Successional Soils

open access: yesFrontiers in Microbiology, 2020
As reported in many aquatic environments, recent studies in terrestrial ecosystems implicate a role for viruses in shaping the structure, function, and evolution of prokaryotic soil communities.

Giant number fluctuations in microbial ecologies

open access: yes, 2012
Statistical fluctuations in population sizes of microbes may be quite large depending on the nature of their underlying stochastic dynamics. For example, the variance of the population size of a microbe undergoing a pure birth process with unlimited ...

ΦCrAss001 represents the most abundant bacteriophage family in the human gut and infects Bacteroides intestinalis [PDF]

open access: yes, 2018
peer-reviewedCrAssphages are an extensive and ubiquitous family of tailed bacteriophages, predicted to infect bacteria of the order Bacteroidales. Despite being found in ~50% of individuals and representing up to 90% of human gut viromes, members of this

In Vivo Targeting of Clostridioides difficile Using Phage-Delivered CRISPR-Cas3 Antimicrobials

open access: yesmBio, 2020
Clostridioides difficile is an important nosocomial pathogen that causes approximately 500,000 cases of C. difficile infection (CDI) and 29,000 deaths annually in the United States.
