Shiga toxins (Stx1 and Stx2) are responsible for initiating haemolytic uraemic syndrome, a serious extraintestinal complication caused by enterohaemorrhagic Escherichia coli O157 : H7 infection in humans. Shiga toxins are classical AB(5)-type exotoxins, consisting of a globotriaosylceramide (Gb(3))-binding B subunit pentamer and an enzymic A subunit. It is demonstrated in this study that Stx2 b...
Typical haemolytic uraemic syndrome (HUS) is a thrombotic microangiopathy, leading to severe renal disease as well as life-threatening extrarenal complications. HUS is primarily caused by infections with enterohaemorrhagic Escherichia coli (EHEC) and 5–20% of EHEC infections result in HUS. EHEC bacteria produce several virulence factors, of which Shiga toxins are believed to play a central role...
Escherichia coli is a widespread bacterium encompassing a variety of strains, ranging from highly pathogenic strains, causing worldwide outbreaks of severe diseases to avirulent, well characterized safe laboratory strains. This study evaluated the prevalence and antibiogram profiles of E. coli pathotypes isolated from the Kat River and Fort Beaufort abstraction water. A total of 171 out of 278 ...
urinary tract infections (utis) are significant health problem, with escherichia coli as the primary pathogen in proximally 80% of cases. the adhesion of e coli to the host cell can be influenced by cell surface hydrophobicity (csh) and is an important factor for the development of infections. this study was conducted to find the relation between csh and one of the adhesions (mannose resistant ...
The type III protein secretion system is an important pathogenicity factor of enteropathogenic and enterohaemorrhagic Escherichia coli pathotypes. The genes encoding this apparatus are located on a pathogenicity island (the locus of enterocyte effacement) and are transcriptionally activated by the master regulator Ler. In each pathotype Ler is also known to regulate genes located elsewhere on t...
