Heteropathogenic virulence and phylogeny reveal phased pathogenic metamorphosis in Escherichia coli O2:H6

EMBO Molecular Medicine, 2014
Extraintestinal pathogenic and intestinal pathogenic (diarrheagenic) Escherichia coli differ phylogenetically and by virulence profiles. Classic theory teaches simple linear descent in this species, where non‐pathogens acquire virulence traits and emerge

Extraintestinal Pathogenic Escherichia coli: Virulence Factors and Antibiotic Resistance

Pathogens, 2021
The One Health approach emphasizes the importance of antimicrobial resistance (AMR) as a major concern both in public health and in food animal production systems. As a general classification, E.

Haemolytic-uraemic syndrome with bacteraemia caused by a new hybrid Escherichia coli pathotype

New Microbes and New Infections, 2014
We describe a new atypical Shiga-toxin-producing Escherichia coli (STEC) responsible for a severe episode of haemolytic–uraemic syndrome in an adult with a relapse associated with bacteraemia. This STECs train of serotype O80:H2 harboured stx2c and stx2d

Development of three multiplex-PCR assays for virulence profiling of different iron acquisition systems in Escherichia coli

Iranian Journal of Microbiology, 2020
Background and Objectives: Escherichia coli is responsible for various enteric and extraintestinal infections in animals and humans. Iron as an essential nutrient, has a proven role in pathogenicity of E. coli. Pathogenic E.

The Diversity of Escherichia coli Pathotypes and Vaccination Strategies against This Versatile Bacterial Pathogen

Microorganisms, 2023
Escherichia coli (E. coli) is a gram-negative bacillus and resident of the normal intestinal microbiota. However, some E. coli strains can cause diseases in humans, other mammals and birds ranging from intestinal infections, for example, diarrhea and ...

Escherichia coli Sequence Type 131-H22 in Parrots from Illegal Pet Trade, Brazil, 2024

Emerging Infectious Diseases
Escherichia coli sequence type 131:H:22 is a consequential lineage of extraintestinal pathogenic E. coli, associated with human pyelonephritis and sepsis. We report the transmission of avian pathogenic E. coli in a parrot rehabilitation center in Brazil

Selection and characterization of siderophores of pathogenic Escherichia coli intestinal and extraintestinal isolates

Open Agriculture, 2021
Microorganisms adopt a unique mechanism for sequestration and transport of bound iron by producing iron-chelating molecules called siderophores. Siderophores play an important role in colonization of microbes in iron-deficient sites of the host, hence ...

Risk of Transmission of Antimicrobial Resistant Escherichia coli from Commercial Broiler and Free-Range Retail Chicken in India

Frontiers in Microbiology, 2017
Multidrug-resistant Escherichia coli infections are a growing public health concern. This study analyzed the possibility of contamination of commercial poultry meat (broiler and free-range) with pathogenic and or multi-resistant E.

Gut Health in Ostriches (Struthio camelus): Insights Into Intestinal Structure, Functions, Microbiome, and Improvement Strategies

Animal Research and One Health, EarlyView.
Our paper systematically reviews the intestinal structure, function, and microbiota of ostriches, along with strategies for improving their gut health. We analyze how these factors collectively influence intestinal homeostasis and ostrich welfare, emphasizing probiotics as a promising intervention to enhance gut health, boost population well‐being, and
