Dancing to Another Tune—Adhesive Moonlighting Proteins in Bacteria

Biology, 2014
Biological moonlighting refers to proteins which express more than one function. Moonlighting proteins occur in pathogenic and commensal as well as in Gram-positive and Gram-negative bacteria.

Beyond Risk: Bacterial Biofilms and Their Regulating Approaches

Frontiers in Microbiology, 2020
Bacterial biofilms are complex surface attached communities of bacteria held together by self-produced polymer matrixs mainly composed of polysaccharides, secreted proteins, and extracellular DNAs. Bacterial biofilm formation is a complex process and can

Changes in the Mare Oviduct Across Different Seasons Throughout the Year

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
Checking changes throughout the year in the oviductal structure (anatomy, permeability, oviductal cellularity and the presence of pathologies) may be relevant to understand the influence on the appearance of problems in oviductal functionality. The oviducts of 56 mares were examined, and the correlations between the time of the year and each of these ...

MrkH, a novel c-di-GMP-dependent transcriptional activator, controls Klebsiella pneumoniae biofilm formation by regulating type 3 fimbriae expression.

PLoS Pathogens, 2011
Klebsiella pneumoniae causes significant morbidity and mortality worldwide, particularly amongst hospitalized individuals. The principle mechanism for pathogenesis in hospital environments involves the formation of biofilms, primarily on implanted ...

The Landscape of Realized Homologous Recombination in Pathogenic Bacteria [PDF]

, 2015
Recombination enhances the adaptive potential of organisms by allowing genetic variants to be tested on multiple genomic backgrounds. Its distribution in the genome can provide insight into the evolutionary forces that underlie traits, such as the ...

A Comprehensive Review of the Multitarget Effects of Subinhibitory Concentrations of Essential Oils Against Salmonella

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 2, March 2026.
ABSTRACT Essential oils (EOs) exhibit antimicrobial activity against foodborne pathogens due to their chemical composition. This review investigates the mechanisms of action of EOs at subinhibitory concentrations against Salmonella strains. Even at subinhibitory concentrations, EOs induce cellular stress and modulate bacterial metabolism. EOs interfere

Reduced diversity and increased virulence-gene carriage in intestinal enterobacteria of coeliac children

BMC Gastroenterology, 2008
Background Coeliac disease is an immune-mediated enteropathology triggered by the ingestion of cereal gluten proteins. This disorder is associated with imbalances in the composition of the gut microbiota that could be involved in its pathogenesis.

Structural and functional studies of Escherichia coli aggregative adherence fimbriae (AAF/V) reveal a deficiency in extracellular matrix binding

Biochimica et Biophysica Acta - Proteins and Proteomics, 2017
Enteroaggregative Escherichia coli (EAEC) is an emerging cause of acute and persistent diarrhea worldwide. The pathogenesis of different EAEC stains is complicated, however, the early essential step begins with attachment of EAEC to intestinal mucosa via

Biofilm Associated Persistence and Drug Tolerance in Mycobacteria Within Host Microenvironments

APMIS, Volume 134, Issue 3, March 2026.
ABSTRACT Biofilms formed by mycobacteria, particularly Mycobacterium tuberculosis (Mtb), represent a major challenge in tuberculosis (TB) treatment due to their highly organized structure and their capacity to induce phenotypic drug tolerance. These three‐dimensional bacterial aggregates are embedded in a self‐produced extracellular matrix that ...

Molecular Characterization of the Escherichia coli Asymptomatic Bacteriuria Strain 83972: The Taming of a Pathogen [PDF]

, 2006
Escherichia coli is the most common organism associated with asymptomatic bacteriuria (ABU). In contrast to uropathogenic E. coli (UPEC), which causes symptomatic urinary tract infections (UTI), very little is known about the mechanisms by which these ...
