Identification of Shiga toxigenic Escherichia coli seropathotypes A and B by multiplex PCR
A multiplex PCR assay was developed to identify the six clinically important enterohemorrhagic Escherichia coli (EHEC) serotypes classified in seropathotypes A and B and to differentiate these from Shiga toxigenic E. coli. The assay simultaneously detects genes for Shiga toxin (stx) and intimin (eae), including allelic variants of both genes, 16S ...

Multiple evolutionary trajectories for non-O157 Shiga toxigenic Escherichia coli [PDF]
AbstractBackgroundShiga toxigenic Escherichia coli (STEC) is an emerging global pathogen and remains a major cause of food-borne illness with more severe symptoms including hemorrhagic colitis and hemolytic-uremic syndrome. Since the characterization of the archetypal STEC serotype, E. coli O157:H7, more than 250 STEC serotypes have been defined.

X-ray microtomographic visualization of Escherichia coli by metalloprotein overexpression [PDF]
This paper reports X-ray microtomographic visualization of the microorganism Escherichia coli overexpressing a metalloprotein ferritin. The three-dimensional distribution of linear absorption coefficients determined using a synchrotron radiation microtomograph with a simple projection geometry revealed that the X-ray absorption was homogeneously ...

Molecular Surveillance of Shiga Toxigenic Escherichia coli O157 by PulseNet USA
PulseNet USA is the national molecular subtyping network system for foodborne disease surveillance. Sixty-four public health and food regulatory laboratories participate in PulseNet USA and routinely perform pulsed-field gel electrophoresis of Shiga toxigenic Escherichia coli isolated from humans, food, water, and the environment on a real-time basis ...

Detection of virulence genes in Shiga toxigenic Escherichia coli isolated from diarrhoeic and non-diarrhoeic pediatric patients in Ondo State, Nigeria [PDF]
Background:Shiga toxigenic Escherichia coli (STEC) is one of the major causes of intestinal infection, bloody and non-bloody diarrhoea and extra-intestinal complications in humans.

Genetic Diversity and Virulence Potential of Shiga Toxin-Producing Escherichia coli O113:H21 Strains Isolated from Clinical, Environmental, and Food Sources [PDF]
Shiga toxin-producing Escherichia coli strains of serotype O113:H21 have caused severe human diseases, but they are unusual in that they do not produce adherence factors coded by the locus of enterocyte effacement.

Presence of activatable Shiga toxin genotype (stx2d) in Shiga toxigenic Escherichia coli from livestock sources [PDF]
Stx2d is a recently described Shiga toxin whose cytotoxicity is activated 10- to 1,000-fold by the elastase present in mouse or human intestinal mucus. We examined Shiga toxigenic Escherichia coli (STEC) strains isolated from food and livestock sources ...
