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 ...

Cloning of terminal transferase cDNA by antibody screening [PDF]

, 1984
A cDNA library was prepared from a terminal deoxynucleotidyltransferase-containing thymoma in the phage vector λgt11. By screening plaques with anti-terminal transferase antibody, positive clones were identified of which some had β-galactosidase-cDNA ...

Lysis-deficient phages as novel therapeutic agents for controlling bacterial infection [PDF]

, 2011
Background Interest in phage therapy has grown over the past decade due to the rapid emergence of antibiotic resistance in bacterial pathogens. However, the use of bacteriophages for therapeutic purposes has raised concerns over the potential

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.

Acquisition of the Sda1-encoding bacteriophage does not enhance virulence of the serotype M1 Streptococcus pyogenes strain SF370 [PDF]

, 2013
The resurgence of invasive disease caused by Streptococcus pyogenes (group A Streptococcus [GAS]) in the past 30 years has paralleled the emergence and global dissemination of the highly virulent M1T1 clone.

Drosophila nuclear lamin precursor Dm0 is translated from either of two developmentally regulated mRNA species apparently encoded by a single gene. [PDF]

, 1988
A cDNA clone encoding a portion of Drosophila nuclear lamins Dm1 and Dm2 has been identified by screening a lambda-gt11 cDNA expression library using Drosophila lamin-specific monoclonal antibodies.

Well-temperate phage: optimal bet-hedging against local environmental collapses [PDF]

, 2015
Upon infection of their bacterial hosts temperate phages must chose between lysogenic and lytic developmental strategies. Here we apply the game-theoretic bet-hedging strategy introduced by Kelly to derive the optimal lysogenic fraction of the total ...

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 ...
