Microbiology and Molecular Biology Reviews, 2003 SUMMARY The majority of the bacterial genome sequences deposited in the National Center for Biotechnology Information database contain prophage sequences. Analysis of the prophages suggested that after being integrated into bacterial genomes, they undergo a complex decay process consisting of inactivating point mutations ...

The ISME Journal, 2023 Environmental bacteria host an enormous number of prophages, but their diversity and natural functions remain largely elusive. Here, we investigate prophage activity and diversity in 63 Erwinia and Pseudomonas strains isolated from flag leaves of wheat ...

Signals triggering prophage induction in the gut microbiota
Molecular Microbiology, 2022 Compared to bacteria of the gut microbiota, bacteriophages are still poorly characterised, and their physiological importance is far less known. Temperate phages are probably a major actor in the gut, as it is estimated that 80% of intestinal bacteria ...

Genome-based identification of active prophage regions by next generation sequencing in Bacillus licheniformis DSM13. [PDF]
PLoS ONE, 2015 Prophages are viruses, which have integrated their genomes into the genome of a bacterial host. The status of the prophage genome can vary from fully intact with the potential to form infective particles to a remnant state where only a few phage genes ...

Microbial Biotechnology, 2022 Gram‐positive bacterial extracellular membrane vesicles (EVs) have been drawing more attention in recent years. However, mechanistic insights are still lacking on how EVs are released through the cell walls in Gram‐positive bacteria.

Diversity of prophage DNA regions of Streptococcus agalactiae clonal lineages from adults and neonates with invasive infectious disease. [PDF]
PLoS ONE, 2011 The phylogenetic position and prophage DNA content of the genomes of 142 S. agalactiae (group-B streptococcus, GBS) isolates responsible for bacteremia and meningitis in adults and neonates were studied and compared.

Small protein modules dictate prophage fates during polylysogeny
bioRxiv, 2022 Prophage lysogeny-to-lysis transitions are controlled by regulatory modules consisting of transcription factors and partner small proteins that are activated through DNA-damage-independent pathways, including by quorum sensing, and these modules ...

CRISPR-Cas Controls Cryptic Prophages [PDF]
International Journal of Molecular Sciences, 2021 The bacterial archetypal adaptive immune system, CRISPR-Cas, is thought to be repressed in the best-studied bacterium, Escherichia coli K-12. We show here that the E. coli CRISPR-Cas system is active and serves to inhibit its nine defective (i.e., cryptic) prophages.

mBio, 2022 The last few decades have demonstrated that membrane vesicles (MVs) produced by microorganisms can have a wide variety of functions. This diversity places MVs at the crossroads of major research topics in current microbiology such as antibiotic ...

BMC Microbiology, 2021 Background The global rise in the incidence of non-tuberculosis mycobacterial infections is of increasing concern due their high levels of intrinsic antibiotic resistance.
