enterohemorrhagic escherichia coli (ehec) of the o157:h7 serotype is a worldwide zoonotic pathogen responsible for the majority of severe cases of human ehec disease. the aim of the present study was to investigate the prevalence of e. coli o157: h7/nm in raw meat samples from two provinces of iran. during a period from march 2010 to march 2011. two hundred and ninety five raw meat samples were...

background and objectives: enterohemorrhagic escherichia coli (ehec) o157:h7 has been recognized as a major food borne pathogen responsible for frequent hemorrhagic colitis and hemolytic uremic syndrome in humans. cattle are important reservoirs of e. coli o157:h7, in which the organism colonizes the intestinal tract and is shed in the feces. objective: vaccination of cattle has significant pot...

background and objective: enterohemorrhagic escherichia coli (ehec) o157:h7 is an important enteric pathogen in human causing bloody or nonbloody diarrhea, which may be complicated by hemolytic uremic syndrome (hus). cattle are an important reservoir of ehec. this research aims at vaccination with a divalent chimer protein composed of espa 120 and intimin 282 and its preventive effect of ehec o...

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...

Background: On 5 June 2012 several enterohemorrhagic Escherichia coli, EHEC, O157:H7 infections were reported to the public health authorities of Limburg. Methods: We performed a case-control study, a trace back/forward investigation and compared strains isolated from human cases and food samples. A case was defined as anyone with a laboratory-confirmed E. coli O157:H7-infection in North-East L...

Here, we present the genome sequence of the Escherichia coli bacteriophage UFV-AREG1. This phage was isolated from cowshed wastewater and showed specificity for enterohemorrhagic E. coli O157:H7 (ATCC 43895), E. coli 0111 (CDC O11ab) and E. coli (ATCC 23229).

Enterohemorrhagic Escherichia coli (EHEC) isolates of serotype O157:H7 are serious foodborne zoonotic pathogens and prime targets for biocontrol using bacteriophages. We report on the complete genome sequences 11 novel lytic bacteriophages, representing three viral genera, isolated from cattle in Hungary that target E. O157 strains.

Escherichia coli strains of serotype O51:H40 were studied with regard to the presence of several virulence properties and their genetic diversity and enteropathogenicity in rabbit ileal loops. This serotype encompasses potential enteropathogenic strains mostly classified as being atypical enteropathogenic E. coli (EPEC) strains, which are genetically closer to enterohemorrhagic E. coli than to ...

background and objectives: a diverse group of escherichia coli are known as enterohemorrhagic escherichia coli (ehec) including o157:h7 and non-o157 ehec. enterohemorrhagic strains are related to severe clinical conditions in humans including hemorrhagic colitis and hemolytic uremic syndrome, and most of the recorded outbreaks occurred due to o157: h7 e. coli . the aim of the present study was ...

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).
