From bacterial predators to partners: phages in agriculture

New Phytologist, EarlyView.
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.

Systematic evaluation of phenotypic variations induced by prophages in a clinical isolate of Pseudomonas aeruginosa

mSystems
With the rise of antibiotic resistance, nosocomial infections caused by Pseudomonas aeruginosa present a significant challenge to healthcare systems. Prophages integrated into bacterial chromosomes play a key role in generating phenotypic and genotypic ...

Hydrogen Evolution via Oxygen Tolerant [NiFe]‐Hydrogenase Immobilized on TiO2 Nanotubes

Nano Select, Volume 7, Issue 1, January 2026.
Hydrogenase‐immobilized TiO2 nanotube was developed by the electropolymerization of polypyrrole and hydrogenase drop‐casting, and cathodic current is reported. Hydrogenase was extracted from E. coli, which can be more oxygen tolerant than the previous hydrogenase electrode.

Update of the list of QPS‐recommended biological agents intentionally added to food or feeds as notified to EFSA

EFSA Journal, Volume 24, Issue 1, January 2026.
Abstract The qualified presumption of safety (QPS) process was developed to provide a harmonised safety assessment approach to support EFSA Scientific Panels and Units. The QPS approach assesses the taxonomic identity, body of relevant knowledge and safety concerns of microorganisms intentionally added to the food and feed chain.

Viral Transmission Dynamics at Single-Cell Resolution Reveal Transiently Immune Subpopulations Caused by a Carrier State Association. [PDF]

PLoS Genetics, 2015
Monitoring the complex transmission dynamics of a bacterial virus (temperate phage P22) throughout a population of its host (Salmonella Typhimurium) at single cell resolution revealed the unexpected existence of a transiently immune subpopulation of host

Superinfection of Lysogenic Strains of Salmonella typhimurium Q1: Prophage Substitution and Double Lysogenization [PDF]

Journal of General Microbiology, 1962
SUMMARY: Strains of Salmonella typhimurium Q1, lysogenized with type A phages, were superinfected with the heterologous free phages of the same group. This produced lysis (productive or vegetative development) and prophage change (either prophage substitution or double lysogenization) in a constant pattern.

Drug Discovery Applications of Nitroso (Hetero)Arene Derivatives

ChemPlusChem, Volume 90, Issue 12, December 10, 2025.
Nitroso (hetero)aromatic compounds are bioactive molecules with antiviral, anticancer, neuroprotective, and antimicrobial properties. This review highlights their mechanisms of action—oxidative stress, DNA damage, and enzyme inhibition—alongside synthesis, structure–activity relationships, and toxicity challenges, offering insight into their ...

Lysogen stability is determined by the frequency of activity bursts from the fate‐determining gene

Molecular Systems Biology, 2010
The ability of living cells to maintain an inheritable memory of their gene‐expression state is key to cellular differentiation. Bacterial lysogeny serves as a simple paradigm for long‐term cellular memory.

Characterization of Novel Bacteriophage vB_KpnP_ZX1 and Its Depolymerases with Therapeutic Potential for K57 Klebsiella pneumoniae Infection

Pharmaceutics, 2022
A novel temperate phage vB_KpnP_ZX1 was isolated from hospital sewage samples using the clinically derived K57-type Klebsiella pneumoniae as a host. Phage vB_KpnP_ZX1, encoding three lysogen genes, the repressor, anti-repressor, and integrase, is the ...

Lysogenic pneumococci and their bacteriophages [PDF]

Journal of Bacteriology, 1979
About half of pneumococci recovered from pediatric patients and one-third of isolates from adult patients yielded bacteriophages active against one or more of four noncapsulated indicator strains of pneumococcus. Strains of capsular types most frequently causing pediatric infections were associated with lysogeny.
