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.

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

Frontiers 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.

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.

Bacterial resistance to temperate phage is influenced by the frequency of lysogenic establishment. [PDF]

iScience
Summary: Temperate phages can shape bacterial community dynamics and evolution through lytic and lysogenic life cycles. In response, bacteria that resist phage infection can emerge.

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.

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.

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

mBio, 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.

Bacteriophage tRNA-dependent lysogeny: requirement of phage-encoded tRNA genes for establishment of lysogeny. [PDF]

mBio
Bacteriophages are large and diverse components of the biosphere, and many phages are temperate. Upon infection, temperate phages can establish lysogeny in which a prophage is typically integrated into the bacterial chromosome.

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?
