Trained Immunity in Childhood Vaccination

Acta Paediatrica, Volume 115, Issue 11, Page 2402-2413, November 2026.
Trained immunity as an emerging concept in paediatric vaccinology. Trained immunity links vaccine stimuli through epigenetic and metabolic reprogramming to enhanced innate immune cell function, thereby strengthening protection against diverse pathogens while promoting adaptive immune responses through more efficient antigen presentation and co ...

Helicobacter pylori virulence factors in duodenal ulceration: A primary cause or a secondary infection causing chronicity [PDF]

, 2006
Reports from countries with a high prevalence of Helicobacter pylori. (H pylori) infection do not show a proportionately high prevalence of duodenal ulceration, suggesting the possibility that H pylori cannot be a primary cause of duodenal ulceration. It

Host and Environmental Factors Outweigh Pathogen in Shaping Skin Microbiome of a Threatened Andean Amphibian Community

Molecular Ecology, Volume 35, Issue 19, October 2026.
ABSTRACT The fungal pathogen Batrachochytrium dendrobatidis (Bd) has driven severe amphibian declines across the Neotropics, yet some species persist under enzootic pathogen conditions following epizootics. We investigated whether skin bacterial communities and host mucosome activity contributed to the persistence of seven amphibian species in a once ...

Differential Regulation of Bvg-Activated Virulence Factors Plays a Role in Bordetella pertussis Pathogenicity [PDF]

Infection and Immunity, 2001
ABSTRACT Bordetella pertussis , the causative agent of whooping cough, regulates expression of many virulence factors via a two-component signal transduction system encoded by the bvgAS regulatory locus.

PTX Instructs the Development of Lung-Resident Memory T Cells in Bordetella pertussis Infected Mice

Toxins, 2021
Whooping cough is a severe, highly contagious disease of the human respiratory tract, caused by Bordetellapertussis. The pathogenicity requires several virulence factors, including pertussis toxin (PTX), a key component of current available vaccines ...

Phenotypic expression of the gene‐for‐gene interaction in plant pathogenic bacteria: An implication for resistance to bacterial diseases by plants

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Plant pathogenic bacteria cause massive losses in agriculture and damage to natural plant habitats. Bacterial pathogens not only reduce crop production, but they also reduce crop quality by releasing toxins into the environment. Pathogenic bacteria that invade plant tissues must overcome the plant's defense mechanisms. Plants possess an innate

The contribution of BvgR, RisA, and RisS to global gene regulation, intracellular cyclic-di-GMP levels, motility, and biofilm formation in Bordetella bronchiseptica

Frontiers in Microbiology
Bordetella bronchiseptica is a highly contagious respiratory bacterial veterinary pathogen. In this study the contribution of the transcriptional regulators BvgR, RisA, RisS, and the phosphorylation of RisA to global gene regulation, intracellular cyclic-

Phosphate Limitation Modulates Vibrio Cholerae Outer Membrane Vesicle Formation, Composition and Toxicity

Journal of Extracellular Biology, Volume 5, Issue 5, May 2026.
ABSTRACT Vibrio cholerae inhabits phosphorus‐poor aquatic environments and host intestine, where it expresses genes regulated by the PhoB/PhoR two‐component system in response to inorganic phosphate (Pi) limitation. Like other Gram‐negative bacteria, V.
