Detection of Escherichia Coli Using PCR Analysis Without DNA Extraction

Folia Medica Indonesiana, 2021
This study aimed to detect Escherichia coli directly without DNA extraction. The nucleus membrane and cell membranes of the Escherichia coli are composed of a phospholipid bilayer, damaged if heated at 950C.

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Phenotypic and Genotypic Characterization of ESBL-, AmpC-, and Carbapenemase-Producing Klebsiella pneumoniae and High-Risk Escherichia coli CC131, with the First Report of ST1193 as a Causative Agent of Urinary Tract Infections in Human Patients in Algeria

Antibiotics
Background: High-risk Escherichia coli clones, such as sequence type (ST)131 and ST1193, along with multidrug-resistant (MDR) Klebsiella pneumoniae, are globally recognized for their significant role in urinary tract infections (UTIs).

Mechanism study of the impact of Escherichia coli on coal flotation.

PLoS ONE, 2022
Escherichia coli as water-borne bacteria exists in the recirculation water of coal flotation and affects the recovery of coal flotation. In order to study the effect of Escherichia coli on coal flotation, we changed the concentration of Escherichia coli ...

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

FEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Analysis of the genetic and phylogenetic context of Escherichia coli O77g:H18 associated with clustered cases of HUS in France in 2025

Applied and Environmental Microbiology
In January 2025, Santé publique France detected several cases of hemolytic uremic syndrome (HUS) in adults caused by a rare serotype of Shiga toxin-producing Escherichia coli, STEC O77g:H18.

Comparative Genomics of Recent Shiga Toxin-Producing Escherichia coli O104:H4: Short-Term Evolution of an Emerging Pathogen

mBio, 2013
The large outbreak of diarrhea and hemolytic uremic syndrome (HUS) caused by Shiga toxin-producing Escherichia coli O104:H4 in Europe from May to July 2011 highlighted the potential of a rarely identified E. coli serogroup to cause severe disease.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Enteroaggregative Escherichia coli [PDF]

Journal of Applied Microbiology, 1998
Enteroaggregative Escherichia coli (EAggEC) are a group of E. coli characterized by the ability to adhere to cultured cell monolayers with an aggregative or 'stacked brick' adhesion phenotype. These strains of E. coli are distinct from other pathogenic groups of E. coli.
