Genetic Diversity and Antimicrobial Resistance of Listeria monocytogenes within Produce Handling and Processing Environments

Creator:: Bland, Rebecca N.
Abstract:: Listeria monocytogenes is a foodborne pathogen frequently associated with food processing environments. Its presence is particularly concerning in facilities handling minimally processed and ready-to-eat foods. Recent outbreaks associated with fresh produce, such as packaged salads and mushrooms, highlight the need to better understand and control these pathogens in environments that...

Development of High-Throughput Screening Methods to Determine Efficacy of “Clean-Label” Antifungals for Application on Cheese

Creator:: Jensen, Kristen
Abstract:: Cheese has been produced since ancient times and continues to be an important nutrient-dense staple in many diets around the world. Cheese quality is of high importance to consumers, and it is important for cheese producers to establish process controls to prevent and control cheese spoilage. Fungal spoilage is of...

Cleaning and Sanitizing Surfaces on Produce Farms: Optimizing What, How, and When

Creator:: Ohman, Erik
Abstract:: Production of fresh produce takes place outdoors, and therefore, is exposed to many routes of contamination (e.g., soil, contaminated water, manure, etc.) by human pathogens. Although precautions are taken to reduce this risk, pathogens can be regularly introduced to produce handling facilities. To manage the risk of cross-contamination from potentially...

Enrichment Isolation of Brettanomyces Yeasts to Probe the Relationship Between Vineyard and Winery Populations

Creator:: Pigao, Kevin E.
Abstract:: The budding yeast Brettanomyces bruxellensis has the potential to spoil fermented beverages and cause financial losses, but also contribute positively to certain products such as Lambic beer. It is most notorious for causing “Brett” spoilage of wine, which is characterized by undesirable aromas such as “bandaid” and “barnyard”, therefore most...

Effects of Whey Protein Isolate on the Human Gut Microbiota and Intestinal Function in Older Adults

Creator:: Rackerby, Bryna
Abstract:: Whey protein is a functional food comprised of numerous bioactive peptides and proteins, including glycomacropeptide (GMP), a hydrophilic casein peptide that separates with the whey fraction during cheesemaking. GMP has a unique amino acid composition, making it a viable nutritional therapy in disorders where certain amino acids are implicated, while...

Species- and Temporal-Specific Coral Microbiome Fluctuations in Response to a Natural Bleaching Event

Creator:: Ewton, Erica M.
Abstract:: Corals provide a diversity of ecosystem services, are among the most biologically diverse ecosystems on Earth, and directly support ~500 million people globally; however, corals are increasingly experiencing significant threats and are undergoing severe bleaching events as the result of the warming climate. Using a two-year data set surrounding a...

Antibiotic Resistance in Septic Sludge and Receiving Environments of Ho Chi Minh City, Vietnam

Creator:: Schutzius, Genevieve Conyers
Abstract:: Approximately ninety percent of urban Vietnamese households are connected to septic tanks, from which up to three-quarters of the sludge is reported to be dumped into waterways in residential areas. Vietnam has a considerable prevalence of antibiotic misuse and resultant antibiotic-resistant bacteria (ARB) in the human microbiome. Due to the...

The Inhibitory Activity of Essential Oil Constituents Against Clostridium perfringens Type A Isolates

Creator:: Alanazi, Saud
Abstract:: C. perfringens type A isolates are the causative agents of C. perfringens type A food poisoning (FP) and non-food-borne (NFB) human gastrointestinal diseases. In this study, we evaluated the antimicrobial effect of essential oil constituents (cinnamaldehyde, eugenol, allyl isothiocyanate (AITC), and carvacrol) against C. perfringens FP and NFB isolates grown...

Immunomodulatory Actions of Bovine Whey Protein Isolates, Glycomacropeptide, and Their Digests: Insights from Macrophage and Human Studies

Creator:: Olsen, Wyatt
Abstract:: Whey protein isolate (WPI) and glycomacropeptide (GMP) have shown potential immunomodulatory properties. In this study, we investigated their effects on pro-inflammatory cytokine secretion using both in vitro and in vivo models. In LPS-stimulated THP-1-derived macrophages, digested WPI and GMP reduced cytokine expression, while whole GMP increased secretion. The in human...
