Human Serum Mediated Bacteriophage Life Cycle Switch in Aggregatibacter actinomycetemcomitans Is Linked to Pyruvate Dehydrogenase Complex

Life, 2023
Antimicrobial resistance is rising as a major global public health threat and antibiotic resistance genes are widely spread among species, including human oral pathogens, e.g., Aggregatibacter actinomycetemcomitans.

Replication Region Analysis Reveals Non-lambdoid Shiga Toxin Converting Bacteriophages

Frontiers in Microbiology, 2021
Shiga toxin is the major virulence factor of enterohemorrhagic Escherichia coli (EHEC), and the gene encoding it is carried within the genome of Shiga toxin-converting phages (Stx phages).

Characterization of prophages in bacterial genomes from the honey bee (Apis mellifera) gut microbiome [PDF]

PeerJ, 2023
The gut of the European honey bee (Apis mellifera) possesses a relatively simple bacterial community, but little is known about its community of prophages (temperate bacteriophages integrated into the bacterial genome).

Isolation and Characterization of a Novel Temperate Escherichia coli Bacteriophage, Kapi1, Which Modifies the O-Antigen and Contributes to the Competitiveness of Its Host during Colonization of the Murine Gastrointestinal Tract

mBio, 2022
In this study, we describe the isolation and characterization of novel bacteriophage vB_EcoP_Kapi1 (Kapi1) isolated from a strain of commensal Escherichia coli inhabiting the gastrointestinal tract of healthy mice. We show that Kapi1 is a temperate phage

Lysogenicity in Xanthomonas pruni [PDF]

Journal of General Microbiology, 1955
An apparently lysogenic strain of Xanthomonas pruni was isolated. A series of experiments was performed to determine whether the isolate was lysogenic or whether it was a case of pseudolysogenesis. The results indicated that it was a true case of lysogenesis. The phage released by the lysogenic organism differed from the one used in its selection.

Evolutionary Stabilization of Cooperative Toxin Production through a Bacterium-Plasmid-Phage Interplay

mBio, 2020
Colicins are toxins produced and released by Enterobacteriaceae to kill competitors in the gut. While group A colicins employ a division of labor strategy to liberate the toxin into the environment via colicin-specific lysis, group B colicin systems lack

Screening for Lysogen Activity in Therapeutically Relevant Bacteriophages

Bio-Protocol, 2021
Lysogenic phages can integrate into their bacterial host’s genome, potentially transferring any genetic information they possess including virulence or resistance genes, and are therefore routinely excluded from therapeutic applications.

From bacterial predators to partners: phages in agriculture. [PDF]

New Phytol
Summary Bacteriophages, viruses that infect bacteria, are critical players for shaping the taxonomic and functional composition of plant‐associated microbiomes. Yet, their roles in plant health remain overlooked, along with their implications for sustainable agriculture.

Transcriptional analysis in bacteriophage Fc02 of Pseudomonas aeruginosa revealed two overlapping genes with exclusion activity

Frontiers in Microbiology, 2023
Little is known about the gene expression program during the transition from lysogenic to lytic cycles of temperate bacteriophages in Pseudomonas aeruginosa.
