A general procedure for small-scale purification of fimbriae expressed by porcine enterotoxigenic Escherichia coli strains

Revista Colombiana de Biotecnología, 2008
Fimbriae expression by enterotoxigenic Escherichia coli strains is a complex process which is controlled by global and local transcriptional regulators and post-transcriptional control.

Targeting aminopeptidase N, a newly identified receptor for F4ac fimbriae, enhances the intestinal mucosal immune response

Mucosal Immunology, 2012
Enterotoxigenic Escherichia coli (ETEC) are a major cause of diarrhea in human and animal. In piglets, ETEC having F4 fimbriae (F4+ ETEC) induce severe diarrhea, dependent on the presence of receptors for F4 (F4R). In this study, porcine aminopeptidase N

Analysis of Human miRNA Derived From Bladder Epithelial Cells Infected With Uropathogenic Escherichia coli

APMIS, Volume 134, Issue 3, March 2026.
ABSTRACT MicroRNAs (miRNAs) have been shown to regulate many cellular processes and to play a role in host‐pathogen interactions. However, the role of miRNA in urinary tract infection (UTI) remains unclear. The aim of this study was to analyze and compare miRNAs from supernatants of human bladder epithelial cells infected with ESBL‐producing (ESBL019 ...

A previously uncharacterized gene stm0551 plays a repressive role in the regulation of type 1 fimbriae in Salmonella enterica serotype Typhimurium

BMC Microbiology, 2012
Background Salmonella enterica serotype Typhimurium produces surface-associated fimbriae that facilitate adherence of the bacteria to a variety of cells and tissues. Type 1 fimbriae with binding specificity to mannose residues are the most commonly found

Body Condition as a Shared Response to Environment in a Commercially Important Demersal Fish Assemblage

Fish and Fisheries, Volume 27, Issue 2, Page 264-284, March 2026.
ABSTRACT Measures of an organism's weight at a given length are often considered reliable indicators of energy reserves or ‘condition’, which can be related to fecundity and risk of mortality. Understanding the impact of environmental change on fish condition may therefore inform sustainable management of human activities in marine ecosystems.

Maltose-binding protein is a potential carrier for oral immunizations [PDF]

, 2011
In humans and most animal species such as pigs, vaccination via the oral route is a prerequisite for induction of a protective immunity against enteropathogens. Hereto, live attenuated microorganisms can be used.

Global Marine Fishery Stock Productivity Under Climate Change

Global Change Biology, Volume 32, Issue 3, March 2026.
In this uniquely extensive global analysis on the productivity of commercial fishery stocks, a common factor was the existence of pronounced heterogeneity, as documented for 710 stocks in the undertaken hindcast over the last decades. Importantly, both winners and losers appear under on‐going climate change, and then seemingly are equally present ...

The dysregulation of innate immunity by Porphyromonas gingivalis in the etiology of Alzheimer's disease

Journal of Internal Medicine, Volume 299, Issue 3, Page 328-348, March 2026.
Abstract The etiology of Alzheimer's disease (AD) remains under active debate. In this perspective, we explore the hypothesis that a primarily infection‐caused chronic dysregulation and weakening of human innate immunity via the underexpression, degradation, and inactivation of innate immune proteins necessary for direct antimicrobial effects and ...

Enterobacter Species: Opportunistic Human and Plant Pathogens With Plant‐Beneficial Traits

Molecular Plant Pathology, Volume 27, Issue 3, March 2026.
The pathogen profile on Enterobacter species synthesises current knowledge on host range, disease symptoms, plant‐beneficial traits and compares genomic features within the genus. ABSTRACT Enterobacter species occur across diverse habitats and are best known for causing opportunistic and nosocomial infections in humans.

Antimicrobial Activity of Ultraviolet C Light as a Potential Novel Treatment for Moraxella bovis Infection—An In Vitro Study

Veterinary Ophthalmology, Volume 29, Issue 2, March 2026.
ABSTRACT Objective To investigate the antimicrobial effect of 275 nm wavelength ultraviolet C (UV‐C) light on M. bovis using an affordable, broadly available modified handheld device and to determine if photoreactivation plays a role in bacterial resistance to UV‐C. Methods UV‐C therapy (UVCT) was evaluated in vitro using triplicates of 3 M.
