چکیده

A novel sequence of 2.9 kb in the intergenic region between the mutS and rpoS genes of Escherichia coli O157:H7 and closely related strains replaces a sequence of 6.1 kb in E. coli K-12 strains. At the same locus in Shigella dysenteriae type 1, a sequence identical to that in O157:H7 is bounded by the IS1 insertion sequence element. Extensive polymorphism in the mutS-rpoS chromosomal region is indicative of horizontal transfer events.

Expression, purification, and immunization of a chimeric protein containing immunogenic regions of flagellin and intimin proteins against E. coli O157: H7

Introduction: Enterohemorrhagic Escherichia coli (EHEC) and serotype O157: H7 is one of the most important diseases causing diarrhea. Shiga-like toxin secreted by the bacteria destroys epithelial cells and, in acute cases, causes hemolytic uremic syndrome (HUS). Antibiotic therapy is not effective against this pathogen, because it increases the production of Shiga toxin. Designing chimeric immu...

Prevalence and molecular characterization of verotoxin-producing Escherichia coli O157:H7 in cattle and sheep in Shiraz-Iran

Shiga toxin producing Escherichia coli have been associated with HUS, HC and TTP in human. We found recto-anal mucosal sample in sheep as well in cattle is the main site for E. coli O157 localization. 1246 E. coli isolates from 872 both healthy and diarrheic animals were analyzed, by screening for the presence of Shiga toxin-producing (VT 1 and VT 2) and intimin (eae) genes used Multiplex PCR. ...

Complete Genome Sequence of SS52, a Strain of Escherichia coli O157:H7 Recovered from Supershedder Cattle

Shiga toxin-producing Escherichia coli O157:H7 causes foodborne infections, and cattle are the primary reservoir. Some animals, known as supershedders, excrete orders of magnitude more E. coli O157:H7 in the feces than normal. Here, we report the complete genome sequence of the SS52 supershedder strain of E. coli O157:H7.

Draft Genome Sequence of Enterohemorrhagic Escherichia coli O157:H7 Strain MC2 Isolated from Cattle in France

Enterohemorrhagic Escherichia coli (EHEC) with serotype O157:H7 is a major foodborne pathogen. Here, we report the draft genome sequence of EHEC O157:H7 strain MC2 isolated from cattle in France. The assembly contains 5,400,376 bp that encoded 5,914 predicted genes (5,805 protein-encoding genes and 109 RNA genes).

Chitosan-Based Intranasal Vaccine against Escherichia coli O157:H7

Background: Enterohemorrhagic Escherichia coli (EHEC) O157:H7 is an infectious zoonotic pathogen causing human infections. These infections, in some cases, can lead to hemolytic uremic syndrome and its life-threatening complications and even death worldwide. The first intimate bacterial adhesion, intimin (I), with its own receptor translocated intimin receptor (Tir) and E. coli secreted protein...
