There is some overlap between certain types of Shiga toxin–producing E. coli and enteropathogenic E. coli. STEC, by definition, are Shiga toxin–positive, but within this group there is a subgroup known as enterohemorrhagic E. coli (EHEC) that, like EPEC, have a locus for enterocyte ...

Stx induced the release of toxin-positive HeLa cell- and platelet-derived microvesicles, detected by flow cytometry, an effect significantly reduced by NF449 or suramin. Suramin decreased microvesicle levels in mice injected with Stx or inoculated with Stx-producing EHEC. Taken together, we describe...
The aim of this study was to investigate the presence of class 1 integrons in a collection of Shiga toxin-producing Escherichia coli (STEC) from different origins and to characterize phenoand genotypically the antimicrobial resistance associated to them. A collection of 649 isolates were screened fo...

Characterization of Shiga Toxin Gene (stx)-Positive and Intimin Gene (eae)-Positive Escherichia coli Isolates from Wastewater of Slaughterhouses in France Wastewater samples from 12 slaughterhouses located in different regions in France were tested for the presence of six-positive and eae-positive Esc...
One of the human isolates could not be definitely identified as a Shiga-toxin producing because it showed positive for PCR using a common primer set for gene family and also positive for 2d subtype, but negative for 1, 2 and for expression of the toxin. The serotypes of the isolates were...
A sorbitol positive, streptomycin resistant STEC strain was isolated from the drinking water, and belonged to the serotype O100:H(-), produced Stx2 toxin (titre 1:8 by reversed-passive latex agglutination method), and carried the genes stx(2e), estIa and irp2. 展开 ...
Shiga toxin-producing Escherichia coli (STEC) is associated with bloody diarrhoea and haemolytic uraemic syndrome (HUS) [1], and human infections emerge as both spontaneous cases and outbreaks [2], [3]. Clinical disease ranges from mild gastroenteritis [4], to bloody diarrhoea, HUS, and death...
In this study, a total of 248 ground beef samples were analyzed for the presence of Shiga toxin-producing Escherichia coli (STEC). Out of these samples, only one (0.4%) tested positive for STEC. Further analysis using PCR confirmed the presence of all tested genes associated with STEC, incl...
