Mutational analysis of the Shiga toxin and Shiga-like toxin II enzymatic subunits [PDF]

Journal of Bacteriology, 1990
The A-subunit polypeptides of Shiga toxin, the Shiga-like toxins (SLTs), and the plant lectin ricin inactivate eucaryotic ribosomes by enzymatically depurinating 28S rRNA. Comparison of the amino acid sequences of the members of the Shiga toxin family and ricin revealed two regions of significant homology that lie within a proposed active-site cleft of

Simple oxidation of pyrimidinylhydrazones to triazolopyrimidines and their inhibition of Shiga toxin trafficking [PDF]

, 2010
The oxidative cyclisation of a range of benzothieno[2,3-d]pyrimidine hydrazones (7a–j) to the 1,2,4-triazolo[4,3-c]pyrimidines (8a–j) catalysed by lithium iodide or to the 1,2,4-triazolo[1,5-c]pyrimidines (10a–j) with sodium carbonate is presented.

Retrograde transport pathways utilised by viruses and protein toxins

Virology Journal, 2006
A model has been presented for retrograde transport of certain toxins and viruses from the cell surface to the ER that suggests an obligatory interaction with a glycolipid receptor at the cell surface. Here we review studies on the ER trafficking cholera

Draft genome sequences of Escherichia coli O157: H7 strains Rafaela_II (clade 8) and 7.1_Anguil (clade 6) from cattle in Argentina [PDF]

, 2015
Escherichia coli O157:H7 is a major etiologic agent of diseases in humans that cause diarrhea, hemorrhagic colitis, and hemolytic-uremic syndrome. Here, we report the draft genome sequences of two strains isolated from cattle that had high levels of ...

Managemental influences on the selective proliferation of two strains of haemolytic Escherichia coli in weaned pigs [PDF]

, 1988
In an experimental study on a piggery it was found that haemolytic Escherichia coli of O-serotypes 138 or 139 proliferated in the intestinal tracts of pigs following weaning, with E.

Shiga Toxin 2–Specific but Not Shiga Toxin 1–Specific Human Monoclonal Antibody Protects Piglets Challenged with EnterohemorrhagicEscherichia coliProducing Shiga Toxin 1 and Shiga Toxin 2 [PDF]

The Journal of Infectious Diseases, 2010
Escherichia coli strains that produce Shiga toxin 2 (Stx2) are isolated from hemolytic-uremic syndrome (HUS) cases more frequently than are strains that produce both Shiga toxin 1 (Stx1) and Stx2, whereas strains that produce only Stx1 are rarely isolated from HUS cases.

Shiga Toxins: Intracellular Trafficking to the ER Leading to Activation of Host Cell Stress Responses

Toxins, 2010
Despite efforts to improve hygenic conditions and regulate food and drinking water safety, the enteric pathogens, Shiga toxin-producing Escherichia coli (STEC) and Shigella dysenteriae serotype 1 remain major public health concerns due to widespread ...

Rapid and Label-Free Immunosensing of Shiga Toxin Subtypes with Surface Plasmon Resonance Imaging

Toxins, 2020
Shiga toxin-producing Escherichia coli (STEC) are responsible for gastrointestinal diseases reported in numerous outbreaks around the world as well as in the United States. Current detection methods have limitation to implement for rapid field-deployable

The association of shiga-like toxin with detergent-resistant membranes is modulated by glucosylceramide and is an essential requirement in the endoplasmic reticulum for a cytotoxic effect [PDF]

, 2006
Receptor-mediated internalization to the endoplasmic reticulum (ER) and subsequent retro-translocation to the cytosol are essential sequential processes required for the productive intoxication of susceptible mammalian cells by Shiga-like toxin-1 (SLTx).

Molecular Characterization of Shiga Toxin Produced by Escherichia coli Isolated from Milk Samples in Baghdad City

Journal of Pure and Applied Microbiology, 2022
Raw milk is a nutrient-rich food that is considered a high-quality nutritional medium for many microorganism, including Escherichia coli. The aim of the present work was the diagnosis, by molecular methods, of Shiga toxins produced by E.
