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...

Greenhouse gas emissions from calf- and yearling-fed beef production systems, with and without the use of growth promotants
Download2012
Baron, V. S, Aalhus, J. L., Basarab, J. A., López-Campos, Ó., Haugen-Kozyra, K., Okine, E. K.
A spring calving herd consisting of about 350 beef cows, 14–16 breeding bulls, 60 replacement heifers and 112 steers were used to compare the whole-farm GHG emissions among calf-fed vs. yearling-fed production systems with and without growth implants. Carbon footprint ranged from 11.63 to 13.22...

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...

Escherichia coli and Salmonella are contaminants in meat products and pose a risk for foodborne illness. Thermal lethality is the traditional method for controlling pathogens in meat products. It is recommended that ground beef and poultry products be cooked to internal temperatures of 71°C and...

Fall 2011
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...

Fall 2016
Patterns of microbial host specificity have been observed at all host-related taxonomic levels, and several studies have demonstrated that Escherichia coli (E. coli) appears to display some level of host adaptation and specificity. Colonization of the gastrointestinal tract by E. coli largely...

Identifying Gene Expression Differences Induced by Diets that Lead to Higher Omega-3 Fatty-Acid Deposition in Beef Cows
DownloadFall 2015
A strong emphasis on the type of fatty acids (FAs) consumed in the human diet has emerged in recent years. In this context, the various health benefits of consuming omega-3 (n-3) polyunsaturated fatty acids (PUFAs) have been widely reported. Supplementation of beef cattle diets with flaxseed, a...

Impact of carbohydrates and carnocyclin A on growth and gene expression of Listeria monocytogenes
DownloadSpring 2024
L. monocytogenes is the foodborne pathogen that causes listeriosis, which has a high fatality rate of 20 to 30%. L. monocytogenes is often associated with ready-to-eat food products. Therefore, techniques to control growth of this organism are needed for the safety of these foods....

Fall 2014
The growth of Listeria monocytogenes and spoilage microorganisms is a concern in sodium-reduced ready-to-eat (RTE) meats. To assess the microbial risk of sodium-reduced RTE meats, the microbiota of retail RTE meats was profiled and the growth of L. monocytogenes and an autochthonous microbiota...
