Microvesicle Involvement in Shiga Toxin-Associated Infection
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).

Do the A Subunits Contribute to the Differences in the Toxicity of Shiga Toxin 1 and Shiga Toxin 2? [PDF]
Shiga toxin producing Escherichia coli O157:H7 (STEC) is one of the leading causes of food-poisoning around the world. Some STEC strains produce Shiga toxin 1 (Stx1) and/or Shiga toxin 2 (Stx2) or variants of either toxin, which are critical for the ...

Shiga Toxins as Antitumor Tools [PDF]
Shiga toxins (Stxs), also known as Shiga-like toxins (SLT) or verotoxins (VT), constitute a family of structurally and functionally related cytotoxic proteins produced by the enteric pathogens Shigella dysenteriae type 1 and Stx-producing Escherichia coli (STEC). Infection with these bacteria causes bloody diarrhea and other pathological manifestations

Phage display and Shiga toxin neutralizers
The current work presents an overview of the use of phage display technology for the identification and characterization of potential neutralizing agents for Shiga toxins. The last major Shiga toxin-associated disease outbreak, which took place in Germany in 2011, showed the international community that Shiga toxins remain a serious threat to public ...

The pathogenic mechanisms of Shiga toxin and the Shiga‐like toxins [PDF]
SummaryIt is now well documented that some enteric bacteria which cause diarrhoeal and/or dysenteric disease produce, at high levels, one or more of a family of protein toxins referred to as Shiga toxin and Shiga‐like toxins (SLTs; alternatively called verocytotoxins or VTs).

Shiga toxins and apoptosis [PDF]
The enteric pathogens Shigella dysenteriae serotype 1 and Shiga toxin-producing Escherichia coli (STEC) cause bloody diarrheal diseases that may progress to life-threatening extraintestinal complications. Although the S. dysenteriae and STEC differ in the expression of a number of virulence determinants, they share the capacity to produce one or more ...

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

Specific Rab GTPase-activating proteins define the Shiga toxin and epidermal growth factor uptake pathways [PDF]
Rab family guanosine triphosphatases (GTPases) together with their regulators define specific pathways of membrane traffic within eukaryotic cells. In this study, we have investigated which Rab GTPase-activating proteins (GAPs) can interfere with the ...

Roles of Shiga Toxins in Immunopathology [PDF]
Shigella species and Shiga toxin-producing Escherichia coli (STEC) are agents of bloody diarrhea that may progress to potentially lethal complications such as diarrhea-associated hemolytic uremic syndrome (D+HUS) and neurological disorders. The bacteria share the ability to produce virulence factors called Shiga toxins (Stxs).
