Refining Viral Production Estimation

Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.
Viral production assays are generally employed to decipher viral‐mediated bacterial mortality rates and prevalence of lysogeny in aquatic ecosystems. Commonly used analytical approaches—linear regression and VIPCAL—often provide significantly different estimates.

Interactions between mobile genetic elements: An anti-phage gene in an integrative and conjugative element protects host cells from predation by a temperate bacteriophage.

PLoS Genetics, 2022
Most bacterial genomes contain horizontally acquired and transmissible mobile genetic elements, including temperate bacteriophages and integrative and conjugative elements.

Boosting Dibenzothiophene Biodesulfurization Through Implantation of a Refactored DBT Pathway in a Tailored Pseudomonas putida Chassis

Microbial Biotechnology, Volume 18, Issue 9, September 2025.
This study engineered a Pseudomonas putida strain to efficiently remove sulfur from dibenzothiophene (DBT) by reordering and optimising the dsz operon from Rhodococcus qingshengii IGTS8, enhancing catalytic activity and stability. The modified strain, P. putida DS006, showed high desulfurization efficiency in model biodesulfurization systems.

Characterization of Novel Broad-Host-Range Bacteriophage DLP3 Specific to Stenotrophomonas maltophilia as a Potential Therapeutic Agent

Frontiers in Microbiology, 2020
A novel Siphoviridae phage specific to the bacterial species Stenotrophomonas maltophilia was isolated from a pristine soil sample and characterized as a second member of the newly established Delepquintavirus genus.

Spontaneous Lysis in Lysogenic Staphylococci.

Experimental Biology and Medicine, 1963
SummaryCultures of lysogenic staphylococci yielded significantly higher plaque counts when plated directly on streptomycin or penicillin with antibiotic resistant indicator strains than when supernatants of centrifuged cultures were assayed. This occurs at cell concentrations that permit significant read-sorption of free phage, which are inactivated ...

The TonB‐Dependent Transport System Facilitates the Uptake of Inorganic Metal Mediators in Pseudomonas putida KT2440 in a Bioelectrochemical System

Microbial Biotechnology, Volume 18, Issue 8, August 2025.
Mediator‐based extracellular electron transfer in Pseudomonas putida KT2440 relies on the TonB‐dependent system for effective mediator (ferricyanide) transport. Transcriptomic and functional analyses confirmed its key role, while OprF overexpression enhanced membrane permeability and current output. These findings clarify mediator uptake mechanisms and

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

Mathematical modelling of CRISPR-Cas system effects on biofilm formation

Journal of Biological Dynamics, 2017
Clustered regularly interspaced short palindromic repeats (CRISPR), linked with CRISPR associated (Cas) genes, can confer adaptive immunity to bacteria, against bacteriophage infections.

Effect of bacteriophage lysin on lysogens [PDF]

Asian Pacific Journal of Tropical Biomedicine, 2011
To study the effect of phage lysin on the growth of lysogens.Sputum specimens processed by modified Petroff's method were respectively treated with phagebiotics in combination with lysin and lysin alone. The specimens were incubated at 37 °C for 4 days.
