Genetically similar strains of Escherichia coli O157:H7 isolated from sheep, cattle and human patients [PDF]

, 2012
Conclusions: The same pathogenic subtypes of VTEC O157:H7, including the highly virulent clade 8, appear to be present in both sheep and cattle in Sweden, suggesting strains can circulate freely between ruminant ...

Behavior of Escherichia coli O157:H7, Listeria monocytogenes, and Salmonella Typhimurium in teewurst, a raw spreadable sausage [PDF]

, 2009
The fate of Listeria monocytogenes, Salmonella Typhimurium, or Escherichia coli O157:H7 were separately monitored both in and on teewurst, a traditional raw and spreadable sausage of Germanic origin. Multi-strain cocktails of each pathogen (ca.

Herd-level risk factors associated with the presence of Phage type 21/28 E. coli O157 on Scottish cattle farms [PDF]

, 2006
<p>Background: E. coli O157 is a bacterial pathogen that is shed by cattle and can cause severe disease in humans. Phage type (PT) 21/28 is a subtype of E.

Expression and regulation of the Escherichia coli O157:H7 effector proteins NleH1 and NleH2 [PDF]

, 2012
E. coli O157 carries two genes encoding the effector proteins NleH1 and NleH2 which are 87% identical. Despite the similarity between the proteins, the promoter regions upstream of the genes encoding the effectors are more divergent suggesting that the ...

Extensive genomic diversity and selective conservation of virulence determinants in enterohemorrhagic Escherichia coli strains of O157 and non O157 serotypes [PDF]

, 2007
Background: Enterohemorrhagic Escherichia coli (EHEC) O157 causes severe food-borne illness in humans. The chromosome of O157 consists of 4.1 Mb backbone sequences shared by benign E.

Integrative Modular, Network-Based, and Machine Learning Framework for Predicting Accessory Genome Functions and Virulence in Escherichia coli O157:H7. [PDF]

Microbiologyopen
An analysis of the accessory genomes from 77 Escherichia coli O157:H7 strains using network and machine learning techniques uncovers modular communities of plasmid‐related virulence associated with IncF replicons. Accessory markers that are not directly linked to toxin genes can effectively predict the virulence status with an AUC of 0.85, facilitating

Characterisation of the effects of salicylidene acylhydrazide compounds on type three secretion in Escherichia coli O157:H7 [PDF]

, 2009
Recent work has highlighted a number of compounds that target bacterial virulence by affecting gene regulation. In this work, we show that small-molecule inhibitors affect the expression of the type III secretion system (T3SS) of <i>Escherichia ...

Effect of long-term starvation on the survival, recovery, and carbon utilization profiles of a bovine Escherichia coli O157:H7 isolate from New Zealand

, 2014
The ability to maintain a dual lifestyle of colonizing the ruminant gut and surviving in nonhost environments once shed is key to the success of Escherichia coli O157:H7 as a zoonotic pathogen.

Intimin, tir, and shiga toxin 1 do not influence enteropathogenic responses to shiga toxin-producing Escherichia coli in bovine ligated intestinal loops [PDF]

, 2002
Shiga toxin-producing Escherchia coli (STEC) comprises a group of attaching and effacing (A/E) enteric pathogens of animals and humans. Natural and experimental infection of calves with STEC may result in acute enteritis or subclinical infection ...
