Plasmid Copy Number Variation Impacts Pathogenicity and Quantification of Curtobacterium flaccumfaciens pv. flaccumfaciens Infecting Mung Bean

Plant Pathology, EarlyView.
Dynamic plasmid copy numbers in the bacterial pathogen Curtobacterium flaccumfaciens pv. flaccumfaciens influence disease expression in mung beans. ABSTRACT In bacteria, plasmids can confer the ability to cause disease. Although they can potentially vary in copy number, little has been reported on the dynamics of plasmids in plant‐pathogenic bacteria ...

Intraspecific Diversity ofYersinia pestis [PDF]

Clinical Microbiology Reviews, 2004
SUMMARYIncreased interest in the pathogenic potential ofYersinia pestishas emerged because of the potential threats from bioterrorism. Pathogenic potential is based on genetic factors present in a population of microbes, yet most studies evaluating the role of specific genes in virulence have used a limited number of strains. ForY.

Insect and Mice Infestations in Gaza Displacement Camps: A Field‐Based Study on Vector‐Borne Diseases Amid the 2023–2025 Gaza War

Public Health Challenges, Volume 4, Issue 4, December 2025.
GRAPHICAL ABSTRACT Conflict‐driven destruction in Gaza has caused water and sanitation collapse, leading to infestations of rodents and insects, escalating public health risks among displaced populations. ABSTRACT The current study investigates the severe environmental and public health impacts resulting from the ongoing conflict in the Gaza Strip ...

Flagellins as Vaccine Adjuvants and Cancer Immunotherapy: Recent Advances and Future Prospects

Immunology, Volume 176, Issue 3, Page 277-303, November 2025.
The figure depicts the role of flagellin in immune cells. Flagellin interacts with TLR5, resulting in the formation of homodimers and the recruitment of MyD88, which activates the IκB and MAPK signalling pathways. This results in the activation of NF‐κB and AP‐1, producing TNF‐α, IL‐6, IL‐8, and IL‐12.

Transfer of the virulence plasmid of Yersinia pestis to Yersinia pseudotuberculosis [PDF]

Infection and Immunity, 1985
Transposon Tn5 insertion derivatives of the virulence plasmid pYV019 of Yersinia pestis were transferred by P1 transduction into a plasmid-free strain of Y. pseudotuberculosis. One of these plasmid derivatives conferred virulence upon the Y. pseudotuberculosis strain.

Humanimals: A Socio‐Ecological Reading of the Marseille Plague of 1720

Journal for Eighteenth-Century Studies, Volume 48, Issue 3, Page 285-301, September 2025.
Abstract The aim of this article is to return to a small number of historically significant first‐person testimonies of the Marseille epidemic of 1720 in order to analyse in detail their construction and depiction of human exceptionality as a form of life in a time of plague.

A loop‐mediated isothermal amplification assay to detect insect‐associated Serratia spp. in the critically endangered insect Dryococelus australis

Insect Conservation and Diversity, Volume 18, Issue 5, Page 775-785, September 2025.
Inclusion of a novel sample cleanup step prior to extraction of bacterial DNA from insect frass enhanced rates of bacterial cell recovery and removed insect and plant cells. Development of a robust LAMP assay allowed detection of insect‐associated members of the Serratia marcescens complex in frass from live insects. Results from the LAMP assay applied

A century of assessment: A systematic review of biothreat risk assessments

Risk Analysis, Volume 45, Issue 9, Page 2808-2821, September 2025.
Abstract Throughout the past century, assessments of the risks and benefits posed by high‐consequence biological agents have guided US decision‐making on weapons research, countermeasure development, and security policy. However, the dispersed nature of these biothreat risk assessments has presented various difficulties, such as duplicative effort ...
