Dynamics of the viral community on the surface of a French smear-ripened cheese during maturation and persistence across production years

The paper studies viral community dynamics on the surface of a French smear-ripened cheese during maturation and across production years, finding persistent dominant phages and shifts in phage-host associations.

The influence of early life exposures on the infant gut virome

This study investigates how early life factors influence the gut virome composition in infants, identifying environmental exposures that shape viral communities and their potential metabolic impacts.

Prophage taming by the adherent-invasive Escherichia coli LF82 upon macrophage infection

This paper studies prophage activity in the adherent-invasive E. coli LF82 strain, showing it tames its most active prophage during macrophage infection to enhance survival.

Streptococcus pyogenes Φ1207.3 is a temperate bacteriophage carrying the macrolide efflux gene pair mef(A)-msr(D) and capable to lysogenise different Streptococci

This paper demonstrates that the prophage phi1207.3 from Streptococcus pyogenes can produce mature phage particles and lysogenize different Streptococci, but lacks sufficient lytic activity to form plaques.

Comparison of interferometric light microscopy with nanoparticle tracking analysis for the study of extracellular vesicles and bacteriophages

This study compares interferometric light microscopy (Videodrop) with nanoparticle tracking analysis (NanoSight and ZetaView) for quantifying and sizing extracellular vesicles and bacteriophages.

Hundreds of viral families in the healthy infant gut

This study manually resolves viral dark matter in a large infant gut virome dataset, identifying over ten thousand viral species across 248 families and expanding bacteriophage taxonomy.

Prophages in the infant gut are largely induced, and may be functionally relevant to their hosts.

This study identifies prophages in infant gut metagenomes, showing they are largely induced and may influence microbiome dynamics through functional elements.

Bacterial predation on T4 phages

The paper demonstrates that bacteria can consume T4 phages, leading to phage disappearance and bacterial growth in wastewater sludge.

Analysis of viromes and microbiomes from pig fecal samples reveals that phages and prophages are not vectors of antibiotic resistance genes

The paper analyzes viromes and microbiomes from pig fecal samples to determine if phages or prophages carry antibiotic resistance genes, finding that ARGs are absent from active phages but present in prophages not detected in viromes.

The enemy from within: a prophage of Roseburia intestinalis systematically turns lytic in the mouse gut, driving bacterial adaptation by CRISPR spacer acquisition

This study shows prophages in Roseburia intestinalis become lytic in the mouse gut, driving bacterial adaptation through CRISPR spacer acquisition and phage resistance.

Viral metagenomic analysis of the cheese surface: a comparative study of rapid procedures for extracting virus-like particles

This study compares methods for extracting viral DNA from cheese surfaces and identifies the most effective procedure for characterizing the virome.
