Shiga Toxin: Expression, Distribution, and Its Role in the Environment

open access: yesToxins, 2011
In this review, we highlight recent work that has increased our understanding of the production and distribution of Shiga toxin in the environment. Specifically, we review studies that offer an expanded view of environmental reservoirs for Shiga toxin ...

Structural Basis of Shiga Toxin Neutralization by Human Antibodies Targeting Canonical Receptor-Binding and Non-Canonical Assembly Sites. [PDF]

open access: yesAdv Sci (Weinh)
Cryo‐electron microscopy structures reveal two distinct neutralization mechanisms of fully human monoclonal antibodies targeting the Shiga toxin 1a B subunit. RDS059 occludes the Gb3 receptor‐binding site, whereas RDS045 engages a lateral quaternary epitope to disrupt holotoxin assembly.

Down-Regulation of Renal Klotho Expression by Shiga Toxin 2

open access: yesKidney & Blood Pressure Research, 2014
Background/Aims: Shiga toxin 2 may trigger classical hemolytic uremic syndrome (HUS) eventually leading to renal failure. Klotho, a transmembrane protein, protease and hormone mainly expressed in kidney is involved in the regulation of renal phosphate ...

Microvesicle Involvement in Shiga Toxin-Associated Infection

open access: yesToxins, 2017
Shiga toxin is the main virulence factor of enterohemorrhagic Escherichia coli, a non-invasive pathogen that releases virulence factors in the intestine, causing hemorrhagic colitis and, in severe cases, hemolytic uremic syndrome (HUS).

Shiga Toxin/Lipopolysaccharide Activates Caspase-4 and Gasdermin D to Trigger Mitochondrial Reactive Oxygen Species Upstream of the NLRP3 Inflammasome

open access: yesCell Reports, 2018
Summary: The non-canonical caspase-4 and canonical NLRP3 inflammasomes are both activated by intracellular lipopolysaccharide (LPS), but the crosstalk between these two pathways remains unclear.

Hemolytic Uremic Syndrome Outbreak in Adults and Shiga Toxin–Producing Escherichia coli Negative for Locus of Enterocyte Effacement, France, 2025 [PDF]

open access: yesEmerging Infectious Diseases
In January 2025, the Escherichia coli National Reference Center of France detected an outbreak of hemolytic uremic syndrome (HUS) in adults, caused by Shiga toxin–producing E. coli negative for locus of enterocyte effacement (LEE). The outbreak included

Isothermal Amplification and Lateral Flow Nucleic Acid Test for the Detection of Shiga Toxin-Producing Bacteria for Food Monitoring

open access: yesChemosensors, 2022
Foodborne bacteria have persisted as a significant threat to public health and to the food and agriculture industry. Due to the widespread impact of these pathogens, there has been a push for the development of strategies that can rapidly detect ...

Influence of temperature and pH on induction of Shiga toxin Stx1a in Escherichia coli

open access: yesFrontiers in Microbiology, 2023
Shiga toxin-producing strains represent pathogenic group that is of concern in food production. The present study evaluated forty-eight E. coli isolates (11 with intact stx gene, while remaining isolates presented only stx-fragments) for Shiga toxin ...

Inhibition of development of Shiga toxin-converting bacteriophages by either treatment with citrate or amino acid starvation [PDF]

open access: yes, 2012
Objectives: Shiga toxin–producing Escherichia coli (STEC) are pathogenic strains, whose virulence depends on induction of Shiga toxin–converting prophages and their subsequent lytic development.

Characterizing RecA-Independent Induction of Shiga toxin2-encoding Phages by EDTA Treatment [PDF]

open access: yes, 2012
The bacteriophage life cycle has an important role in Shiga toxin (Stx) expression. The induction of Shiga toxin-encoding phages (Stx phages) increases toxin production as a result of replication of the phage genome, and phage lysis of the host cell also
