Viral Regulation on Bacterial Community Impacted by Lysis-Lysogeny Switch: A Microcosm Experiment in Eutrophic Coastal Waters

Frontiers in Microbiology, 2019
Marine viruses are major drivers of global biogeochemical cycles and energy fluxes, yet the importance of viral impacts on the succession and diversity of the bacterial community remains largely unexplored.

An extended catalog of integrated prophages in the infant and adult fecal microbiome shows high prevalence of lysogeny

Frontiers in Microbiology, 2023
Background and aimsThe acquisition and gradual maturation of gut microbial communities during early childhood is central to an individual’s healthy development. Bacteriophages have the potential to shape the gut bacterial communities.

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.

Staphylococcus aureus Prophage-Encoded Protein Causes Abortive Infection and Provides Population Immunity against Kayviruses

mBio, 2023
Both temperate and obligately lytic phages have crucial roles in the biology of staphylococci. While superinfection exclusion among closely related temperate phages is a well-characterized phenomenon, the interactions between temperate and lytic phages ...

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.

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.

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

Molecular 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.

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 ...
