Characterization And Investigation Of Fungi Inhabiting The Gastrointestinal Tract Of Healthy And Diseased Humans, Mallory J. Suhr
Dissertations & Theses in Food Science and Technology
Gastrointestinal microbiome studies have failed to include fungi in total community analyses. As a result, their diversity and function in the gut is poorly understood. Recent work has begun to uncover the role intestinal fungi play in diet, immune system development, interactions with other microorganisms in the gut, and pathogenesis of diseases. Advances in sequencing technologies allow for the ability to profile the fungal gut microbiome (“mycobiome”) in healthy and diseased states. This thesis explores the mycobiome in 1) healthy humans with a vegetarian diet and 2) pediatric small bowel transplant recipients that develop fungal bloodstream infections.
The gut mycobiome ...

Effects Of Panelist Participation Frequency And Questionnaire Design On Overall Acceptance Scoring For Food Sensory Evaluation In Consumer Central Location Tests, 2015 Brigham Young University - Provo
Effects Of Panelist Participation Frequency And Questionnaire Design On Overall Acceptance Scoring For Food Sensory Evaluation In Consumer Central Location Tests, Mauresa Bastian
All Theses and Dissertations
Two studies were conducted to determine the effect of panelist participation frequency and specific aspects of questionnaire design on overall acceptance scoring in consumer central location tests. Regarding participation frequency, research subjects who participate frequently in some survey types are known to provide responses that differ from subjects who participate less frequently, known as panel conditioning. With respect to questionnaire design, overall acceptance (OA) question placement and usage of pre-evaluation instructions (PEI) in questionnaires for food sensory analysis may bias consumers' scores via carry-over effects. To investigate these concerns, data from consumer sensory panels previously conducted at a central location ...

After repeated subirrigation with synthetic wastewater, lettuce leaves and soil were collected at three sequential harvests. The internalization frequency of Salmonella in lettuce was low. A soil horizon-influenced Salmonella concentration gradient was determined with concentrations in bottom soil 2 log CFU/g higher than in top soil. Lincomycin and sulfamethoxazole were recovered from lettuce leaves at concentrations as high as 822 ng ...
Determining The Fate Of Non-O157 Shiga Toxin-Producing Escherichia Coli In Dairy Compost During Storage Using The Optimized Detection Method, Hongye Wang
Shiga toxin-producing Escherichia coli (STEC), a member of Enterobacteriaceae family, has been recognized as emerging pathogens. Dairy compost is commonly applied to farmland as a soil amendment. Despite the agricultural benefit of manure-based soil amendment, the inadequately treated compost can contribute to fresh produce contamination on the farm. Moreover, the epidemiological results showed that the non-O157 STEC cases have surpassed those of E. coli O157. Therefore, it is critical to evaluate the behavior of non-O157 STEC strains in the dairy manure-based compost. The objectives of this study were to: 1) optimize a culturing method for detecting non-O157 STEC from dairy ...
Combining Modified Atmosphere Packaging And Nisin To Extend The Shelf Life Of Atlantic Salmon (Salmo Salar), Dong Han

Hand Hygiene Promotion: An Essential Strategy For Preventing Foodborne Disease In Elementary Schools, 2015 Clemson University
Hand Hygiene Promotion: An Essential Strategy For Preventing Foodborne Disease In Elementary Schools, Zhangqi Wang
Student absenteeism is a pervasive problem in the United States, causing a number of educational, economic, and institutional problems. Hand-hygiene interventions have been reported to be a method for reducing illness-associated student absenteeism. As an increasing number of schools offer self-service, including salad bars and bowls of whole fresh fruit, opportunities for the transmission of foodborne pathogens via hands could possibly increase illness-associated student absenteeism. To address this problem, we conducted a two-phase study. First, we conducted a systematic literature review to evaluate peer-reviewed studies (N=24) that reported an association between hand hygiene interventions and illness-associated absenteeism reduction in ...

Self-Learning, Dvd-Based Education Versus Traditional Education Approaches To Improve The Safety Of Warfarin Use Among Patients With Atrial Fibrillation, Jessica Oliver Hatch
All Graduate Theses and Dissertations
Atrial fibrillation (AF) is a common cardiac arrhythmia that requires extensive medical and pharmaceutical management. The coagulation antagonist warfarin is commonly prescribed to reduce AF-associated stroke. Although warfarin effectively mediates thromboembolitic risk, its management is complex as many factors influence its therapeutic range including: genetics, diet, medication, and herbal and dietary supplement (HDS) interactions. Lack of patient knowledge regarding these factors contributes to poor patient outcomes. With the emerging epidemic of AF, readily available educational tools are necessary to improve patient outcomes while reducing clinician burden.
The purpose of this study was to develop both a self-learning, DVD-based and one-on-one ...
Effects Of Blast Chilling On Fresh Pork Quality In Chops From The Longissimus Dorsi, 2015 Iowa State University
Effects Of Blast Chilling On Fresh Pork Quality In Chops From The Longissimus Dorsi, Aaron M. Blakely, Edward M. Steadham, Kenneth J. Prusa, Christine A. Fedler, Elisabeth J. Huff-Lonergan, Steven M. Lonergan
Animal Industry Report
Carcasses (n=40) with defined fat free lean and carcass weight were selected 45 minutes postmortem. Carcasses were split, and sides subjected to conventional or blast chilling regimens. Sides that were blast chilled had Longissimus dorsi (LD) chops with slower pH decline, greater cook loss and greater Warner-Bratzler Shear force than chops from conventionally chilled sides. These results demonstrate that current blast chilling practices have the potential to negatively impact pork tenderness.
Effects Of Blast Chilling On Fresh Pork Quality In Cuts From The Psoas Major, Semimembranosus, And Triceps Brachii, Aaron M. Blakely, Edward M. Steadham, Kenneth J. Prusa, Christine A. Fedler, Elisabeth J. Huff-Lonergan, Steven M. Lonergan
Animal Industry Report
Carcasses (n=40) with defined fat free lean and carcass weight were selected 45 minutes postmortem. Carcasses were split and sides subjected to conventional chill (CC) or blast chilling (BC) regimens. The Psoas Major (PM) from BC sides had increased purge loss, but was juicier, more tender and less chewy than the PM from CC sides. The Semimembranosus (SM) from BC sides had higher 30 hour pH, darker color scores, and had a lower Hunter a value than the SM from CC sides. No treatment effect was found in the Triceps Brachii.

Prediction Of Loin, Belly And Jowl Iv Based On Diet Composition Verses Daily Fatty Acid Intake, Trey A. Kellner, Kenneth J. Prusa, John F. Patience
Animal Industry Report
Iodine value product (IVP) is commonly used to predict carcass fat iodine value (CIV). However, when higher fat diets are employed, IVP tends to emphasize the quantity of fat in the diet more than the composition of that fat. The objective of this experiment was to compare the effectiveness in predicting CIV by IVP versus individual fatty acid content in the diet or their daily intake. Forty-two gilts and 21 barrows (PIC 337 × C22/29) with an average initial weight of 77.8 ± 0.38 kg were allotted based on sex and weight across 7 treatments: a control diet with ...
