Antimicrobial applications of treatments using light pulses emitted from light emitting diodes (LED)
DownloadSpring 2022
Low water activity (aw) foods have been associated with several foodborne outbreaks and recalls. Eradication of foodborne microorganisms like Salmonella and Escherichia coli from low aw foods is challenging, as they are resistant to conventional decontamination practices. High intensity light...

Application of antimicrobials for the elimination of Escherichia coli and Listeria monocytogenes in brine injected beef
DownloadFall 2013
The application of antimicrobials to a brine-injected raw beef roast for the elimination/inhibition of heat resistant Escherichia coli and Listeria monocytogenes was investigated. The choice of antimicrobials for use in brine injected beef was based on minimum bactericidal concentration in brine...

Characterization of Heat Resistant Escherichia coli Isolates Associated with Human Infection
DownloadSpring 2021
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...

Characterization of novel envelope proteins and their relationship with the Cpx response and stress resistance in Escherichia coli
DownloadFall 2022
Stress is a major factor every organism needs to mitigate to survive. Environmental factors such as oxygen content, temperature, and alkalinity can all induce stress and prevent life from progressing. For Escherichia coli and other members of the mammalian gastrointestinal tract they need to...

Detection of Shiga Toxin-Producing Escherichia coli Using Loop Mediated Isothermal Amplification
DownloadFall 2013
Shiga toxin-producing Escherichia coli (STEC) is a worldwide health concern. To detect STEC, a loop mediated isothermal amplification reaction (LAMP) was optimized to detect shiga toxin genes. LAMP’s performance was compared to conventional and real-time (RT) PCR using two product detection...

Spring 2019
The safety of low water activity (aW) foods is a concern due to the survival of low-infectious dose pathogens such as Escherichia coli and Salmonella. Desiccation of non-heat resistant E. coli and Salmonella increases their heat resistance; therefore, a non-thermal alternative is necessary to...

Environmental Risk Factors Associated with Contamination of Private Drinking Water Wells with Escherichia coli
DownloadFall 2014
The focus of this research was to identify environmental risk factors that play a critical role in the contamination of drinking water wells with Escherichia coli. This study used data from a case control-study carried out between April 2005 and September 2006 in Ontario and Alberta, using...

Spring 2019
During food processing, Escherichia coli are exposed to stress from oxidation, osmolarity and temperature, and have developed mechanisms to survive. A highly heat resistant strain of E. coli AW1.7 was isolated from a beef carcass after thermal processing and it has a genomic island called the...

Fall 2017
Strains of Escherichia coli may survive heat or pressure stress, acquire specific virulence genes and cause severe human diseases. The locus of heat resistance (LHR) has been identified as an important heat resistant element in E. coli. The objective of this thesis was to explore the role of the...

Heat and Pressure Resistance of Escherichia coli and Its Inactivation In the Presence of Antimicrobial Compounds
DownloadFall 2014
Verotoxigenic Escherichia coli (VTEC) are pathogens causing severe foodborne disease. E. coli AW1.7 is a heat resistant beef carcass isolate that may be used as a surrogate organism to study the survival of VTEC on food. This dissertation examines the heat and pressure resistance of E. coli and...
