PorA of the Type IX Secretion Is a Ligand of the PorXY Two‐Component Regulatory System in Porphyromonas gingivalis

open access: yesMolecular Microbiology, Volume 123, Issue 6, Page 569-585, June 2025.
Porphyromonas gingivalis exports several virulent proteins, including gingipain proteinases, via the type 9 secretion system. Expression of several T9SS component proteins is regulated by the PorA‐PorY‐PoX‐SigP signaling cascade. This study presents a novel role of PorA in the signaling cascade.

Global dissemination of a multidrug resistant Escherichia coli clone. [PDF]

open access: yes, 2014
Escherichia coli sequence type 131 (ST131) is a globally disseminated, multidrug resistant (MDR) clone responsible for a high proportion of urinary tract and bloodstream infections. The rapid emergence and successful spread of E.

RMSD analysis of structures of the bacterial protein FimH identifies five conformations of its lectin domain

open access: yesProteins: Structure, Function, and Bioinformatics, 2020
FimH is a bacterial adhesin protein located at the tip of Escherichia coli fimbria that functions to adhere bacteria to host cells. Thus, FimH is a critical factor in bacterial infections such as urinary tract infections and is of interest in drug ...

The Study of Escherichia coli as Antimicrobial‐Resistant Sentinel Microorganism Isolated in the Farms of Three Districts of Ankara by MALDI‐TOF MS and Genomic Analysis

open access: yesVeterinary Medicine and Science, Volume 11, Issue 3, May 2025.
The antibiotic susceptibility of Escherichia coli isolates isolated from faeces and soil samples collected from farms in three districts where livestock farming activities are intensively carried out via phenotypic and genotypic methods and the presence of extended‐spectrum beta‐lactamases (ESBLs) via a double‐disc synergy test. Only one E. coli strain

In silico Study of Toll-Like Receptor 4 Binding Site of FimH from Uropathogenic Escherichia coli

open access: yesJournal of Medical Microbiology and Infectious Diseases, 2014
Introduction : The innate immune system as the first line of defense against the pathogens recognizes pathogen-associated molecular patterns (PAMPs) by Toll-Like Receptors (TLRs). Interaction of bacterial PAMPs by TLRs results in activation of innate and

Immune modulation by group B Streptococcus influences host susceptibility to urinary tract infection by uropathogenic Escherichia coli [PDF]

open access: yes, 2012
Urinary tract infection (UTI) is most often caused by uropathogenic Escherichia coli (UPEC). UPEC inoculation into the female urinary tract (UT) can occur through physical activities that expose the UT to an inherently polymicrobial periurethral, vaginal,

Broad‐Spectrum Antimicrobial and Antibiofilm Activities of Halogenated Anilines Against Uropathogenic Escherichia coli and ESKAPE Pathogens

open access: yesMicrobial Biotechnology, Volume 18, Issue 5, May 2025.
This study evaluates the antimicrobial and antibiofilm activities of halogen‐substituted aniline derivatives, 4‐bromo‐3‐chloroaniline (4B3CA) and 3,5‐dibromoaniline (3,5‐DBA), against uropathogenic E. coli (UPEC) and some ESKAPE pathogens, with MICs of 200 and 100 μg/mL, respectively, and a common biofilm IC50 of 10 μg/mL.

The epidemic of extended-spectrum-beta-lactamase-producing Escherichia coli ST131 is driven by a single highly pathogenic subclone, H30-Rx [PDF]

open access: yes, 2013
The Escherichia coli sequence type 131 (ST131) clone is notorious for extraintestinal infections, fluoroquinolone resistance, and extended-spectrum beta-lactamase (ESBL) production, attributable to a CTX-M-15-encoding mobile element.
