Spring 2011
Several obstacles to widespread use of bacteriocins in food have been identified, including lack of specific, rapid quantitation methods, and little data on their efficacy in food systems. The first objective of this study was to develop a specific, rapid quantitation method for bacteriocins...

The mechanism of heat resistance in an exceptionally resistant strain of E. coli was investigated. E. coli AW1.7 was compared to a heat sensitive strain, E. coli GGG10. The heat resistance of both strains was increased by inclusion of NaCl, but only E. coli AW1.7 exhibited a consistent heat...

Investigation on the uptake of functional proteins and infectious prions into wheat plants through the root system
DownloadSpring 2014
Prions are the proteinaceous particle responsible for infections in a class of neurodegenerative diseases. These diseases affect a number of mammals including cervids where it is termed Chronic Wasting Disease (CWD). Prions enter the environment and persist for years. Plants have the ability to...

Implications of direct contacts between mule deer (Odocoileus hemionus) on transmission of chronic wasting disease
DownloadFall 2022
Chronic wasting disease (CWD) is a fatal, prion disease of cervids that was first detected in Alberta in 2005. Transmission of CWD occurs by direct contact with an infected individual or via contaminated environments. I investigated the seasonal effects of landscape heterogeneity on direct,...

Enterococcus faecalis 710C is a lactic acid bacterium that produces two bacterocins, ent7A and ent7B. Both ent7A and ent7B have strong activity against gram-positive food pathogens including Listeria spp., Clostridium spp., vancomycin-resistant enterococci (VRE) and methicillin-resistant...

Consumers’ concerns about animal diseases, production and processing methods could drive their choices of food products. Consumers’ choices of food products will influence their nutritional status. Understanding preferences for food products could inform policy and assist in forecasting future...

Ecology and management of white-tailed deer (Odocoileus virginianus) and mule deer (O. hemionus) of east-central Alberta in relation to chronic wasting disease
DownloadFall 2010
Chronic wasting disease (CWD) is a fatal pathogen affecting white-tailed and mule deer in east-central Alberta, and I addressed two current limitations of CWD management. First, to improve precision and accuracy of density estimates obtained from aerial surveys, I evaluated alternative survey...

Effect of bacterial stress response on pathogen enumeration and its implications for food safety
DownloadSpring 2011
To determine the impact of stress response on enumeration, cell association status and the viability of Escherichia coli DH5α, Staphylococcus aureus ATCC 13565 and Listeria monocytogenes CDC 7762 were evaluated using fluorescence microscopy and were compared with the outcomes of traditional plate...

Fall 2012
Provided that infectious prions (PrPTSE) are inactivated, composting of specified risk material (SRM) may be a viable alternative to rendering and land filling. The overall objective of this research was to utilize laboratory-scale composters to assess the degradation of SRM and PrPTSE during...

An input-output analysis of the economic impacts of chronic wasting disease and bovine spongiform encephalopathy in Alberta and Canada
DownloadSpring 2011
This thesis utilizes input-output analysis to calculate the economic impacts from potential prion diseases outbreaks in Alberta and Canada. Both chronic wasting disease and bovine spongiform encephalopathy have the capacity to not only affect the farmed cervid and cattle industries, but to impact...
