The risk of Salmonella spp. from small poultry operations in Oregon

Creator:: Diaz-Hui, Jonathan
Abstract:: Salmonella is a bacterium responsible for several illnesses, including typhoid fever, paratyphoid fever, and salmonellosis. It is commonly found in animal products, including poultry. Determination of potential reservoirs of Salmonella contamination is important to mitigate the risk of transmission and possible outbreaks. Outbreaks can negatively impact the livelihood of local...

The frequency of Ceratonova shasta genotypes in Manayunkia speciosa host genotypes

Creator:: Messmer, Madison M.
Abstract:: Ceratonova shasta is a myxozoan parasite that affects populations of salmonid species in the Pacific Northwest and is the cause of enteronecrosis. It has a complex life cycle involving two hosts; a definitive annelid host, Manayunkia speciosa (polychaete), and an intermediate salmonid host. Klamath River M. speciosa are genetically variable...

The Effects of the Immunity Factor Relish on Aging Phenotypes in Drosophila melanogaster

Creator:: Kumar, Nandita
Abstract:: Aging is a complex biological phenomenon that alters many different physiological processes. Although many age-related phenotypes, such as neurodegeneration, weakening circadian rhythms, and inflammaging, are well-studied, the links between them are not. To elucidate these links we created an inflammation-like state in Drosophila melanogaster by overexpressing Relish (Rel), an NFκB...

The Effect of Dissolved O₂ Level on KHV Reactivation from Latency and Pathologic analysis during KHV Reactivation

Creator:: Chen, Sammi
Abstract:: Koi herpesvirus (KHV) is a new emerging viral pathogen of koi and common carps. It has been demonstrated that KHV becomes latent in the white blood cells in the recovered koi. The latent KHV can be reactivated under stressful conditions, such as heat and injury, and the reactivated viruses can...

Studies on the evolution and expression of the Type II ferripyoverdine receptor gene fpvAIIb in Pseudomonas aeruginosa

Creator:: Glover, Rochelle
Abstract:: When iron levels are low, the opportunistic pathogen Pseudomonas aeruginosa secretes the high-affinity iron-binding siderophore pyoverdine. The cognate ferripyoverdine receptor, FpvA, has gained attention as the most divergent gene in the organism’s genome, showing substantial evidence of positive selection. S-type pyocins, bacteriocins with specificity to Pseudomonads, enter cells through FpvA...

Nonmedical prescription stimulant use: exploring student perceptions and university response

Creator:: Foss, Austyn
Abstract:: This thesis explores trends and perceptions surrounding nonmedical use of prescription stimulants by university students throughout the United States. Furthermore, this study evaluated how universities in Oregon have responded to increased rates of nonmedical prescription stimulant use on campuses across the country. The following research questions are addressed: 1) What...

Metagenomics and metatranscriptomics of the leaf- and root-associated microbiomes of Zostera marina and Zostera japonica

Creator:: Wojahn, John Michael Adrian
Abstract:: A great deal of research has been focused on the microbiomes of terrestrial angiosperms (flowering plants), but much less research has been performed on the microbiomes of aquatic angiosperms (Turner et al. 2013). Eelgrass beds are extremely productive ecosystems that provide habitat for many marine organisms, such as fish, shellfish,...

Establishment of an in vitro model to study persistence in Mycobacterium avium subspecies hominissuis

Creator:: Armstrong, Elyssa L.
Abstract:: Mycobacterium avium subspecies hominissuis (MAH) is the most common pathogen among non-tuberculous mycobacteria, causing disease in immunocompromised individuals. An intracellular bacterium, MAH resides within the phagosome, a vesicle formed by macrophages as they engulf invading pathogens. Here, a subpopulation of MAH regresses into a nonreplicative state called persistence, allowing them...

Contribution of native plasmids to fitness of Pantoea vagans C9-1, a biological control agent for fire blight of apple and pear

Creator:: Klein, Jeannie M.
Abstract:: Pantoea vagans C9-1 (C9-1) is a biological control agent sprayed onto apple and pear trees during bloom for suppression of fire blight, a devastating bacterial disease caused by Erwinia amylovora. Prior bioinformatics studies of C9-1 focused on predicted phenotypes associated with the three native megaplasmids, pPag1, pPag2, and pPag3, and...

Characterizing Rhythms in Circadian Gene Expression Following Chronic Binge-Like Alcohol Drinking in HDID Mice

Creator:: Batish, Tanvi
Abstract:: Mammals exhibit circadian rhythms in several physiological processes controlled by a core set of circadian genes that make up the so-called molecular clock. Disruptions in these rhythms, and variations in circadian genes, are associated with the development of psychiatric disorders, including addiction. However, the effect of chronic binge-like alcohol drinking...

Aryl Hydrocarbon Receptor Activation and the Prevention of Type 1 Diabetes

Creator:: Newman, Matthew
Abstract:: The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor that is an important regulator of immune responses in various disease models. In the non-obese diabetic (NOD) mouse model of type 1 diabetes, activation of this receptor leads to suppression of the autoimmune response and limits immune cell infiltration of...

A Different Kind of Fatigue : A Cross-Cultural Analysis of the Etiology of Burnout in Medical Literature

Creator:: Tran, Jessica
Abstract:: The rate of physician dissatisfaction is steadily rising. Between 2011 and 2012, the number of physicians that would not choose a career in medicine if given the opportunity to decide again increased by 15% (Adams). This discontentment has major repercussions in the midst of the rising need for physicians: it...
