Preferential attachment of Escherichia coli to different particle size fractions of an agricultural grassland soil. [PDF]

, 2007
This study reports on the attachment preference of a faecally derived bacterium, Escherichia coli, to soil particles of defined size fractions. In a batch sorption experiment using a clay loam soil it was found that 35% of introduced E.

Orientational Control is an Efficient Control Mechanism for Phase Switching in the E coli fim System [PDF]

, 2006
The 'fim' system in 'E. coli' controls the expression of type-1 fimbriae. These are hair-like structures that can be used to attach to host cells. Fimbriation is controlled by a mechanism called ''orientational control''.

Effects of green tea on Escherichia coli as a uropathogen

Journal of Traditional and Complementary Medicine, 2015
Escherichia coli is the most common cause of urinary tract infections. The development of antibiotic resistance in E. coli is an important problem. Finding alternative antimicrobial agents from plant extracts has received growing interest. Camellia sinensis is a safe, nontoxic, cheap beverage that has been reported to have antimicrobial effects against

The Dissemination of Multidrug Resistance (MDR) and Extensively Drug Resistant (XDR) among Uropathogenic E. coli (UPEC) Isolates from Urinary Tract Infection Patients in Babylon Province, Iraq

مجلة بغداد للعلوم, 2019
Antibiotic resistance is a problem of deep scientific concern both in hospital and community settings. Rapid detection in clinical laboratories is essential for the judicious recognition of antimicrobial resistant organisms.

The Study of Uropathogenicity Factors for Escherichia Coli Strains.

Current health sciences journal, 2016
Urinary tract infection (UTI) is the most common form of extraintestinal Escherichia Coli infection (E.coli), and E. coli is the most common cause of UTI.The aim of this paper is to study the uropathogenicity factors for some strains of E.coli involved in the etiology of UTI and the affiliationof urinary E.coli strains to the serogroups involved in the

Characterisation of the effects of salicylidene acylhydrazide compounds on type three secretion in Escherichia coli O157:H7 [PDF]

, 2009
Recent work has highlighted a number of compounds that target bacterial virulence by affecting gene regulation. In this work, we show that small-molecule inhibitors affect the expression of the type III secretion system (T3SS) of <i>Escherichia ...

Invasion of vaginal epithelial cells by uropathogenic Escherichia coli [PDF]

Nature Communications, 2020
AbstractHost-associated reservoirs account for the majority of recurrent and oftentimes recalcitrant infections. Previous studies established that uropathogenic E. coli – the primary cause of urinary tract infections (UTIs) – can adhere to vaginal epithelial cells preceding UTI. Here, we demonstrate that diverse urinary E. coli isolates not only adhere

Time‐Resolved Effects of Cold Atmospheric Plasma on E. coli GW‐AmxH19 Transcriptome and Proteome in an Emulated Wastewater Environment

PROTEOMICS, EarlyView.
ABSTRACT Cold atmospheric plasma (CAP) is effective against a variety of microorganisms. Here, we described effects on an Escherichia coli strain isolated from hospital wastewater caused by treatment with physical plasma. E. coli GW‐AmxH19 was incubated in artificial wastewater and treated for 15 min with CAP.

Catch-bond mechanism of the bacterial adhesin FimH [PDF]

, 2016
Ligand-receptor interactions that are reinforced by mechanical stress, so-called catch-bonds, play a major role in cell-cell adhesion. They critically contribute to widespread urinary tract infections by pathogenic Escherichia coli strains.
