Project description:Shiga toxin type 2 (Stx2) is the main virulence factor produced by Stx-producing Escherichia coli (STEC) responsible for hemorrhagic colitis and the life-threatening sequela hemolytic uremic syndrome.
Project description:Escherichia coli O157:H7 is a non-invasive Shiga toxin (Stx)-producing pathogen that causes gastroenteritis and hemolytic uremic syndrome characterized by acute kidney injury. Stx binding to cells induces release of extracellular vesicles (EVs) containing the toxin. This study aimed to demonstrate the lethal effects of toxin-positive vesicles compared to free toxin, and the importance of the Stx receptor, globotriaosylceramide (Gb3), for these effects.
Project description:Transcriptomes of 24 clinical strains of E. coli O157:H7 that differ phylogenetically and by Shiga toxin profiles were compared after 30 min co-incubation with epithelial cells.
