The Intriguing Evolutionary Journey of Enteroinvasive E. coli (EIEC) toward Pathogenicity

Frontiers in Microbiology, 2017
Among the intestinal pathogenic Escherichia coli, enteroinvasive E. coli (EIEC) are a group of intracellular pathogens able to enter epithelial cells of colon, multiplicate within them, and move between adjacent cells with a mechanism similar to Shigella,

Serotype-dependent adhesion of Shiga toxin-producing Escherichia coli to bovine milk fat globule membrane proteins

Frontiers in Microbiology, 2022
Shiga toxin-producing Escherichia coli (STEC) are food-borne pathogens that can cause severe symptoms for humans. Raw milk products are often incriminated as vehicule for human STEC infection.

Escherichia coli σ70 senses sequence and conformation of the promoter spacer region [PDF]

, 2010
In bacteria, promoter identification by RNA polymerase is mediated by a dissociable p factor. The housekeeping σ70 factor of Escherichia coli recognizes two well characterized DNA sequence elements, known as the ‘-10’ and ‘-35’ hexamers.

Mutation rate plasticity in rifampicin resistance depends on Escherichia coli cell–cell interactions [PDF]

, 2014
Variation of mutation rate at a particular site in a particular genotype, in other words mutation rate plasticity (MRP), can be caused by stress or ageing. However, mutation rate control by other factors is less well characterized.

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.

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).
