Identification and Characterization of a Newly Isolated Shiga Toxin 2-Converting Phage from Shiga Toxin-Producing Escherichia coli [PDF]

Infection and Immunity, 1998
ABSTRACT Shiga toxins 1 (Stx1) and 2 (Stx2) are encoded by toxin-converting bacteriophages of Stx-producing Escherichia coli (STEC), and so far two Stx1- and one Stx2-converting phages have been isolated from two STEC strains (A. D. O’Brien, J. W. Newlands, S. F.

Retrograde transport pathways utilised by viruses and protein toxins [PDF]

, 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

Pathogenic Potential to Humans of Bovine Escherichia coli O26, Scotland [PDF]

, 2012
Escherichia coli O26 and O157 have similar overall prevalences in cattle in Scotland, but in humans, Shiga toxin–producing E. coli O26 infections are fewer and clinically less severe than E. coli O157 infections.

Nitric oxide‐enhanced Shiga toxin production was regulated by Fur and RecA in enterohemorrhagic Escherichia coli O157

MicrobiologyOpen, 2017
Enterohemorrhagic Escherichia coli (EHEC) produces Shiga toxin 1 (Stx1) and Shiga toxin 2 (Stx2). Nitric oxide (NO), which acts as an antimicrobial defense molecule, was found to enhance the production of Stx1 and Stx2 in EHEC under anaerobic conditions.

Eeyarestatin 1 interferes with both retrograde and anterograde intracellular trafficking pathways [PDF]

, 2011
Background: The small molecule Eeyarestatin I (ESI) inhibits the endoplasmic reticulum (ER)-cytosol dislocation and subsequent degradation of ERAD (ER associated protein degradation) substrates.

Shiga Toxin 2 Targets the Murine Renal Collecting Duct Epithelium [PDF]

Infection and Immunity, 2009
ABSTRACTHemolytic-uremic syndrome (HUS) caused by Shiga toxin-producingEscherichia coliinfection is a leading cause of pediatric acute renal failure. Bacterial toxins produced in the gut enter the circulation and cause a systemic toxemia and targeted cell damage. It had been previously shown that injection of Shiga toxin 2 (Stx2) and lipopolysaccharide

Shiga toxin-producing Escherichia coli O157:H7 in milk and milk products in Ogun State, Nigeria [PDF]

Veterinaria Italiana, 2014
Shiga toxin producing Escherichia coli (STEC) O157 is a major cause of food-borne illnesses in humans. This study investigated the presence of STEC O157 in milk and milk products in Ogun State, Nigeria. Of a total of 202 samples 10 (5%) were positive for

Shiga Toxin-Bearing Microvesicles Exert a Cytotoxic Effect on Recipient Cells Only When the Cells Express the Toxin Receptor

Frontiers in Cellular and Infection Microbiology, 2020
Shiga toxin is the main virulence factor of non-invasive enterohemorrhagic Escherichia coli strains capable of causing hemolytic uremic syndrome. Our group has previously shown that the toxin can reach the kidney within microvesicles where it is taken up
