Mitomycin C eliminates cyanobacterial transcription without detectable prophage induction in a Microcystis-dominated harmful algal bloom in Lake Erie

Microbiology Spectrum
Although evidence indicates that viruses are important in the ecology of Microcystis spp., many questions remain. For example, how does Microcystis exist at high, bloom-associated cell concentrations in the presence of viruses that infect it?

phiD12-Like Livestock-Associated Prophages Are Associated With Novel Subpopulations of Streptococcus agalactiae Infecting Neonates

Frontiers in Cellular and Infection Microbiology, 2019
Group B Streptococcus (GBS) is a major cause of invasive disease in neonates worldwide. Monitoring data have revealed a continuing trend toward an increase in neonatal GBS infections, despite the introduction of preventive measures.

Viral metagenomics reveals diverse virus-host interactions throughout the soil depth profile

mBio, 2023
Soil microbes play pivotal roles in global carbon cycling; however, the fundamental interactions between microbes and their infecting viruses remain unclear.

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

, 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,

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

, 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 ...

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

Frontiers 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

, 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 ...

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

, 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

Biochemical Studies of Lysogeny

Journal 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 ...

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

Frontiers 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.
