A new topology of the HK97-like fold revealed in Bordetella bacteriophage by cryoEM at 3.5 A resolution. [PDF]

, 2013
Bacteriophage BPP-1 infects and kills Bordetella species that cause whooping cough. Its diversity-generating retroelement (DGR) provides a naturally occurring phage-display system, but engineering efforts are hampered without atomic structures.

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.

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.

Effects of Noise on Ecological Invasion Processes: Bacteriophage-mediated Competition in Bacteria

, 2006
Pathogen-mediated competition, through which an invasive species carrying and transmitting a pathogen can be a superior competitor to a more vulnerable resident species, is one of the principle driving forces influencing biodiversity in nature.

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.

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.

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.
