Flagella, Type I Fimbriae and Curli of Uropathogenic Escherichia coli Promote the Release of Proinflammatory Cytokines in a Coculture System

Microorganisms, 2021
Background. Urinary tract infections (UTIs) are a public health problem in Mexico, and uropathogenic Escherichia coli (UPEC) is one of the main etiological agents. Flagella, type I fimbriae, and curli promote the ability of these bacteria to successfully

First Report of blaCTX‐M‐15 in a Marine Thermotolerant Enterobacter Isolate From Bangladesh: Genomic Insights Into Halotolerance and Antimicrobial Resistance

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Marine‐derived Enterobacter kobei, exhibiting thermotolerance and salt tolerance, is ESBL‐producing and harbors AMR genes (blaCTX‐M‐15, qnrS1) and mobile genetic elements, indicating environmental spread of antimicrobial resistance. ABSTRACT Marine ecosystems are becoming important reservoirs for antimicrobial resistance (AMR). However, genomic data on

Blocking Extracellular Cyclophilin A‐Mediated Adhesion Protects Against Bacterial Infection

MedComm, Volume 7, Issue 10, October 2026.
eCypA promotes bacterial infection by upregulating TGF‐β signaling‐dependent adhesion receptor expression. Pathogens such as IAV, GAS, S. P., and K. P. induce eCypA secretion. Binding of eCypA with TβR2 enhances the affinity of TGF‐β1 and TβR2, which positively regulates adhesion receptors expression via the TGF‐β/Smad signaling pathway, thereby ...

Blockage of bacterial FimH prevents mucosal inflammation associated with Crohn’s disease

Microbiome, 2021
Background An Escherichia coli (E. coli) pathotype with invasive properties, first reported by Darfeuille-Michaud and termed adherent-invasive E. coli (AIEC), was shown to be prevalent in up to half the individuals with Crohn’s Disease (CD), suggesting ...

Two‐Dimensional Materials For Lateral Flow Assays: A Critical Review of Functional Roles and Translational Challenges

VIEW, Volume 7, Issue 5, October 2026.
2D nanosheets, with large surface area, excellent optical/electrical properties, and high specificity, combine with lateral flow assay strips to enable rapid, readable detection, boosting the strips’ development and applications. Abstract Lateral flow assays (LFAs) are widely used for point‐of‐care diagnostics, but their detection capability remains ...

Selection for nonspecific adhesion is a driver of FimH evolution increasing Escherichia coli biofilm capacity

, 2022
International audienceBacterial interactions with surfaces rely on the coordinated expression of a vast repertoire of surface-exposed adhesins. However, how bacteria dynamically modulate their adhesion potential to achieve successful surface colonization

Type 1 fimbriae are important factors limiting the dissemination and colonization of mice by Salmonella Enteritidis and contribute to the induction of intestinal inflammation during Salmonella invasion

Frontiers in Microbiology, 2015
We have recently shown that S. Gallinarum type 1 fimbriae with endogenous mannose-resistant (MR) variant of the FimH protein increase systemic dissemination of S. Gallinarum and colonization of internal organs in comparison to the S.
