Enterohemorrhagic Escherichia coli producing Shiga toxins 1 and/or 2 have become major foodborne pathogens. The specific binding of Shiga toxin 1 B-subunit to its receptor, a neutral glycolipid globotriaosylceramide Gb(3), on the apical surface of colonic epithelium followed by toxin entry into cells are the initial steps of the process, which can result in toxin transcytosis and systemic effec...

Shiga toxin is a bacterial toxin consisting of A and B subunits. Generally, the essential cytotoxicity of the toxin is thought to be mediated by the A subunit, which possesses RNA cleavage activity and thus induces protein synthesis inhibition. We previously reported, however, that the binding of the Shiga toxin 1-B subunit to globotriaosyl ceramide, a functional receptor for Shiga toxin, induc...

BACKGROUND Hemolytic uremic syndrome associated with Shiga toxin-producing Escherichia coli O157:H7 has been widely known as a common cause of acute renal failure in children. There are only a few reports of sporadic Shiga toxin-producing Escherichia coli-hemolytic uremic syndrome in adults in the USA. Analyses from the 2011 outbreak of hemolytic uremic syndrome associated with Escherichia coli...

Infection of humans with Shiga toxin-producing Escherichia coli O157:H7 and Shigella dysenteriae 1 is strongly associated with vascular endothelial cell damage and the development of hemolytic-uremic syndrome. The cytotoxic effect of Shiga toxins on vascular endothelial cells in vitro is enhanced by prior exposure to bacterial lipopolysaccharide (LPS) or either of the host cytokines tumor necro...

Shiga toxin-producing Escherichia coli have been associated with food-borne illnesses. Pasteurization is used to inhibit microbial growth in milk, and an open question is whether milk pasteurization inactivates Shiga toxins. To answer this question we measured Shiga toxin's inhibition effect on Vero cell dehydrogenase activity and protein synthesis. Our data demonstrate that Shiga toxin 2 (Stx2...

Shiga toxin 2 (Stx2) from the foodborne pathogen Escherichia coli O157:H7 is encoded on a temperate bacteriophage. Toxin-encoding phages from C600::933W and from six clinical E. coli O157:H7 isolates were characterized for PCR polymorphisms, phage morphology, toxin production, and lytic and lysogenic infection profiles on O157 and non-O157 serotype E. coli. The phages were found to be highly va...

The Shiga toxin family consists of Shiga toxin (Stx) that is produced as a virulence factor by Shigella dysenteriae, and the Shiga-like toxins produced by certain strains of enterohemorrhagic E. coli as well as by some other types of bacteria. Infection with bacteria producing these toxins is a threat to human health even in industrialized countries, as the initial diarrhea caused by the infect...
