Insights into the genome architecture and evolution of Shiga toxin encoding bacteriophages of Escherichia coli

open access: yesBMC Genomics, 2021
Background A total of 179 Shiga toxin-producing Escherichia coli (STEC) complete genomes were analyzed in terms of serotypes, prophage coding regions, and stx gene variants and their distribution.

Effect of Stx B subunit on the neutralizing activity of anti-Stx IgY. [PDF]

open access: yes, 2013
(A, B) Anti-Stx-1 IgY and (C, D) anti-Stx-2 IgY were mixed with serial dilutions of Stx-1BH and Stx-2BH, and incubated for 2 h at 37°C. (A, B) hpStx-1 and (C, D) hpStx-2 were added to the mixture, and incubated at 37°C for a further 1 h.

Shiga Toxin Is Transported into the Nucleoli of Intestinal Epithelial Cells via a Carrier-Dependent Process

open access: yesToxins, 2010
Shiga toxin (Stx) produced by the invasive Shigella dysenteriae serotype 1 (S. dysenteriae1) causes gastrointestinal and kidney complications. It has been assumed that Stx is released intracellularly after enterocyte invasion by S. dysenteriae1. However,

Intervention with Shiga Toxin (Stx) Antibody after Infection by Stx‐ProducingEscherichia coli [PDF]

open access: yesThe Journal of Infectious Diseases, 2001
Shiga toxins (Stxs) produced by Escherichia coli (STEC) cause systemic vascular damage, manifested as hemolytic uremic syndrome in humans and as edema disease in pigs. Edema disease, a naturally occurring disease of pigs, was used to determine whether Stx antibodies, administered after infection and after the onset of Stx production, could prevent the ...

In VivoAutopolysialylation and Localization of the Polysialyltransferases PST and STX [PDF]

open access: yesJournal of Biological Chemistry, 1998
A select group of mammalian proteins have been shown to possess alpha2,8-polysialylated oligosaccharide chains. The best studied of these proteins is the neural cell adhesion molecule (NCAM). Polysialylation of NCAM has been shown to decrease NCAM-dependent and independent cell adhesion.

Neutralizing activity of anti-Stx IgY on Stx bound to target cells. [PDF]

open access: yes, 2013
(A) hpStx-1 and (C) hpStx-2 were added to HeLa 229 cells at a concentration of 20 times CD50, and kept on ice for 30 min. Cells were extensively washed with cold DMEM to remove unbound Stx.

Bovine non-O157 Shiga toxin 2-containing Escherichia coli isolates commonly possess stx(2-EDL933) and/or stx(2vhb) subtypes [PDF]

open access: yes, 2003
stx(2) genes from 138 Shiga toxin-producing Escherichia coli (STEC) isolates, of which 127 were of bovine origin (58 serotypes) and 11 of human origin (one serotype; O113:H21), were subtyped.

Dynamic changes in Shiga toxin (Stx) 1 transducing phage throughout the evolution of O26:H11 Stx-producing Escherichia coli [PDF]

open access: yes, 2023
Shiga toxin (Stx) is the key virulence factor of Stx-producing Escherichia coli (STEC). All known Stxs (Stx1 and Stx2) are encoded by bacteriophages (Stx phages).

Cheating, facilitation and cooperation regulate the effectiveness of phage‐encoded exotoxins as antipredator molecules

open access: yesMicrobiologyOpen, 2019
Temperate phage encoded Shiga toxin (Stx) kills the bacterivorous predator, Tetrahymena thermophila, providing Stx+ Escherichia coli with a survival advantage over Stx− cells. Although bacterial death accompanies Stx release, since bacteria grow clonally

Shiga Toxin Interaction with Human Intestinal Epithelium

open access: yesToxins, 2011
After ingestion via contaminated food or water, enterohaemorrhagic E. coli colonises the intestinal mucosa and produces Shiga toxins (Stx). No Stx-specific secretion system has been described so far, and it is assumed that Stx are released into the gut ...
