The Importance of Escherichia coli O157:H7 in Foodborn Infection
Enterohemorrhagic Escherichia coli O157: H7 is one of the most important causes of bloody diarrhea. This bacterium is able to make bloody diarrhea or Hemorrhagic Colitis (HC) through verotoxin or shigatoxin production, and in acute forms it may lead to Hemolytic Uremic Syndrome (HUS) or Thrombotic Thrombocytopenic Purpurea (TTP). Contamination with E. coli O157:H7 usually happens after consumpt...
متن کاملsodC genes expression in Escherichia coli O157:H7 strains.
INTRODUCTION E. coli O157:H7 has three sodC genes encoding for Cu,Zn superoxide dismutase. We evaluated the expression of chromosomal sodC in distinct phases of growth in different strains, and we examined the mutual capability of chromosomal and prophagic genes to influence their expression. METHODS We used One Step real-time RT-PCR technology to study the expression of sodC genes in several...
متن کاملAdherence Patterns of Verotoxigenic Escherichia coli (VTEC) Non-O157 Strains Isolated from Faecal Samples in Iran
The adherence property of 70 verotoxigenicE. coli (VTEC) strains, not belonging to O157: H7 serotype (non-O157) was checked on HeLa cells adherence assay. These strains were isolated from patients with diarrhea and healthy individuals. The results obtained in this study revealed that localised adherence (LA) was manifested by 3 strains of which two belonged to serogroups O111, O127 and the thir...
متن کاملGenetically similar strains of Escherichia coli O157:H7 isolated from sheep, cattle and human patients
BACKGROUND Comparatively little is known about the prevalence or the molecular characteristics of the zoonotic pathogen E. coli O157:H7 in the sheep reservoir. To investigate this and determine the host specificity of subclones of the bacterium, we have conducted a slaughterhouse prevalence study in sheep and compared the collected isolates to O157:H7 previously isolated from cattle and human p...
متن کاملMolecular characterization of Escherichia coli O157:H7 strains isolated from different sources and geographic regions
Escherichia (E.) coli serotype O157:H7 is a globally distributed human enteropathogen and is comprised of microorganisms with closely related genotypes. The main reservoir for this group is bovine bowels, and infection mainly occurs after ingestion of contaminated water and food. Virulence genetic markers of 28 O157:H7 strains were investigated and multilocus enzyme electrophoresis (MLEE) was u...
