Shiga toxin-producing Escherichia coli (STEC) is a bacterial pathogen associated with foodborne diarrheal disease. Infection with STEC presents as a mild, watery diarrhea to hemorrhagic colitis and can progress to the life-threatening complication, hemolytic uremic syndrome. Cattle are recognized...
Development and validation of a surrogate strain cocktail to evaluate bactericidal effects of pressure on verotoxigenic Escherichia coliDownload
Many strains of verotoxigenic Escherichia coli (VTEC) are highly resistant to pressure. To facilitate future studies to improve the elimination of VTEC by pressure processing of food, this study developed and validated a cocktail of non-pathogenic strains of E. coli with equal or higher...
From Nuisance to Resource: Understanding Microbial Sources of Contamination in Urban Stormwater-Impacted Bodies of Water Intended for Water Reuse ActivitiesDownload
Harvesting stormwater provides the province of Alberta, Canada, with a strategy to address the growing demands on water resources due to climate change and projected population growth. However, stormwater reuse poses a variety of challenges due to the potential of this source to be of low water...
Escherichia coli AW1.7 is a heat resistant food isolate and the occurrence of pathogenic strains with comparable heat resistance may pose a risk to food safety. To identify the genetic determinants of heat resistance, 29 strains of E. coli that differed in their of heat resistance were analyzed...
Mechanisms of pressure-mediated cell death and injury in Escherichia coli: From fundamentals to food applicationsDownload
High hydrostatic pressure is commercially applied to extend the shelf life of foods, and to improve food safety. Current applications operate at ambient temperature and 600 MPa or less. However, bacteria that may resist this pressure level include the pathogens Staphylococcus aureus and strains...
The Spatiotemporal Occurrence and Recovery of Shiga Toxin-producing Escherichia coli (STEC) in Well-sourced Drinking Water from Southern Alberta, CanadaDownload
Shiga toxin-producing Escherichia coli (STEC) are important enteric pathogens that cause significant morbidity and mortality worldwide, as well as in Canada. Drinking water is a key exposure pathway for STEC infection and the occurrence of these pathogens in drinking water sources represents an...
