Within‐Host Mathematical Modeling of Antibiotic‐phage Treatments on Lysogenic and Nonlysogenic Bacteria Dynamics

Mathematical Methods in the Applied Sciences, Volume 48, Issue 10, Page 10550-10570, 15 July 2025.
ABSTRACT Bacteriophages, or phages (viruses of bacteria), play significant roles in shaping the diversity of bacterial communities within the human gut. A phage‐infected bacterial cell can either immediately undergo lysis (virulent/lytic infection) or enter a stable state within the host as a prophage (lysogeny) until a trigger event, called prophage ...

Opinion of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) on defining pathogenic strains of Shiga toxin‐producing Escherichia coli

Food Risk Assess Europe, Volume 3, Issue 3, July 2025.
ABSTRACT Shiga toxin‐producing Escherichia coli (STEC) are pathogenic E. coli strains that have been associated with a wide range of human clinical illness ranging from mild diarrhoea to bloody diarrhoea (BD) and haemolytic uremic syndrome (HUS). In its opinion of 18 May 2017, the French Agency for Food, Environmental and Occupational Health and Safety

Pavlovian‐Type Learning in Environmental Bacteria: Regulation of Herbicide Resistance by Arsenic in Pseudomonas putida

Environmental Microbiology, Volume 26, Issue 12, December 2024.
Similar to Pavlov's dog experiment, where two different stimuli can elicit the same response, environmental bacteria exposed to one of two simultaneous and unrelated stimuli may eventually trigger responses to both. ABSTRACT The canonical arsRBC genes of the ars1 operon in Pseudomonas putida KT2440, which confer tolerance to arsenate and arsenite, are ...

Phages for Phage Therapy: Isolation, Characterization, and Host Range Breadth

Pharmaceuticals, 2019
For a bacteriophage to be useful for phage therapy it must be both isolated from the environment and shown to have certain characteristics beyond just killing strains of the target bacterial pathogen.

Estimating the Importance of Viral Contributions to Soil Carbon Dynamics

Global Change Biology, Volume 30, Issue 10, October 2024.
Written Summary: Viruses are ubiquitous in soils and impact global carbon cycling through infection of microbial hosts. Using existing data from the literature, we generate a global budget of the carbon potentially released from microbial biomass by viral infections in soils.

Mycobacterium Phage Butters-Encoded Proteins Contribute to Host Defense against Viral Attack

mSystems, 2020
A diverse set of prophage-mediated mechanisms protecting bacterial hosts from infection has been recently uncovered within cluster N mycobacteriophages isolated on the host, Mycobacterium smegmatis mc2155.

DNA Packaging Specificity in the λ‐Like Phages: Gifsy‐1

Molecular Microbiology, Volume 122, Issue 4, Page 491-503, October 2024.
Dimeric λ TerS and chimera transition points. The N‐termini of each TerS derives from a λ‐like source phage: Gifsy‐1, 21, and N15 (labeled arrows). The N‐terminus includes the winged‐helix‐turn‐helix (HTH) DNA‐binding motif that confers the source phage's DNA packaging specificity.

Physiochemically and Genetically Engineered Bacteria: Instructive Design Principles and Diverse Applications

Advanced Science, Volume 11, Issue 30, August 14, 2024.
Engineered bacteria specifically refer to advanced physiochemical or genetic modifications of diagnostic bacteria, which can compensate for the shortcomings of natural strains. After engineering, these diagnostic bacteria are encouraged to lyse tumors, regulate immunity and cellular communication such immune cells, influence metabolic pathways ...

Population fitness and the regulation of Escherichia coli genes by bacterial viruses.

PLoS Biology, 2005
Temperate bacteriophage parasitize their host by integrating into the host genome where they provide additional genetic information that confers higher fitness on the host bacterium by protecting it against invasion by other bacteriophage, by increasing ...

Specific Integration of Temperate Phage Decreases the Pathogenicity of Host Bacteria

Frontiers in Cellular and Infection Microbiology, 2020
Temperate phages are considered as natural vectors for gene transmission among bacteria due to the ability to integrate their genomes into a host chromosome, therefore, affect the fitness and phenotype of host bacteria. Many virulence genes of pathogenic
