Current trends in detecting non-O157 Shiga toxin-producing Escherichia coli in food.

Foodborne pathogens and disease, 2013
Non-O157 Shiga toxin-producing Escherichia coli (non-O157 STEC) strains are increasingly recognized as important foodborne pathogens worldwide. Together with E.

Optimal growth temperature of O157 and non-O157 Escherichia coli strains [PDF]

Letters in Applied Microbiology, 2001
There are several biological characteristics that differ between Escherichia coli O157:H7, a dangerous food-borne pathogen, and the other serotypes of E. coli.The optimal growth temperatures (T(opt)) were determined for 32 E. coli strains, whether each strain belonged to the O157 serotype or not.

The endophytic lifestyle of Escherichia coli O157:H7: quantification and internal localization in roots.

Phytopathology, 2013
The foodborne pathogen Escherichia coli O157:H7 is increasingly associated with fresh produce (fruit and vegetables). Bacterial colonization of fresh produce plants can occur to high levels on the external tissue but bacteria have also been detected ...

Deposition and survival of Escherichia coli O157:H7 on clay minerals in a parallel plate flow system.

Environmental Science and Technology, 2013
Understanding bacterial pathogens deposition and survival processes in the soil-groundwater system is crucial to protect public health from soilborne and waterborne diseases.

Antibacterial Mechanism of (−)-Nortrachelogenin in Escherichia coli O157

Current Microbiology, 2015
(-)-Nortrachelogenin is a lignan belonging to group of polyphenolic compounds. Its biological properties in mammalian cells are well-studied; however, its biological effects in microorganisms remain poorly understood. Its efficacy against pathogenic bacteria, including antibiotic-resistant strains, was investigated and it was found that bacteria are ...

Phytochemicals in lowbush wild blueberry inactivate Escherichia coli O157:H7 by damaging its cell membrane.

Foodborne pathogens and disease, 2013
The antimicrobial activity and model of action of polyphenolic compounds extracted from lowbush wild blueberries (LWB) were studied against Escherichia coli O157:H7.

Occurrence of Escherichia coli O157 in Finnish cattle

Veterinary Microbiology, 2001
Bovine faecal samples were collected during June-December 1997 at 14 major abattoirs slaughtering cattle in Finland. Escherichia coli O157 was isolated from 19 of the 1448 samples (1.31%) after enrichment and immunomagnetic separation (IMS). The positive faecal isolates originated from 16 farms and eight abattoirs. The occurrence of E.

Preharvest control of Escherichia coli O157 in cattle1

Journal of Animal Science, 2007
Bovine manure is an important source of Escherichia coli O157 contamination of the environment and foods; therefore, effective interventions targeted at reducing the prevalence and magnitude of fecal E. coli O157 excretion by live cattle (preharvest) are desirable.

Epidemiology and spectrum of disease of Escherichia coli O157

Current Opinion in Infectious Diseases, 2003
The Shiga toxin-producing Escherichia coli strains, such as E. coli O157:H7, have emerged as major diarrheal pathogens both in the United States and elsewhere. These organisms are important because gastrointestinal infection (afebrile hemorrhagic colitis) can trigger microangiopathic hemolytic anemia and renal failure (hemolytic uremic syndrome ...

Factors affecting the occurrence of Escherichia coli O157 contamination in irrigation ponds on produce farms in the Suwannee River Watershed.

Canadian Journal of Microbiology (print), 2013
Outbreaks of enteritis caused by Escherichia coli O157 associated with fresh produce have resulted in questions about the safety of irrigation water; however, associated risks have not been systematically evaluated.
