Consequences of Influenza A Virus on Pneumococcal Biofilm Formation and Stability in the Absence of Host Factors

Creator:: Nutter, Laura
Abstract:: Streptococcus pneumoniae and Influenza A Virus both primarily infect the upper respiratory tract, with more severe disease occurring during coinfection than would be caused by either pathogen independently. Until recently, characterization of the interactions between these two pathogens has occurred exclusively in the context of a host or using host-derived...

Chemical and Genetic Investigations of Toxic Freshwater Cyanobacterial Blooms for Improved Monitoring and Understanding of Lake Ecology

Creator:: Collart, Lindsay P.
Abstract:: Toxin production by cyanobacterial harmful algal blooms (cyanoHABs) in freshwater systems has lasting ecological and human impacts. Nutrients, light availability, hydrology, and microbial community composition impact the frequency and intensity of toxic cyanoHABs. Climate change will exacerbate toxic cyanoHABs, making real time and predictive monitoring a vital tool for managing...

How Do Parasites Infect Salmon? Comparative Transcriptomics Reveal Myxozoan Adaptations for Parasitism

Creator:: Americus, Benjamin
Abstract:: The phylum Cnidaria contains three main branches: Anthozoa (corals, sea anemones) Medusozoa (jellyfish, hydra), and Endocnidozoa. This latter branch is characterized by parasitism and contains the microscopic fish-parasites Myxozoa. Myxozoa are highly simplified, consisting of only a few cell types, however they have retained the nematocyst stinging cells and complex...

Comparing Sediment Microbial Communities of Arctic Beaver Ponds to Tundra Lakes and Streams

Creator:: Shannon, Kelly
Abstract:: In recent decades the habitat of North American beaver (Castor canadensis) has expanded from boreal forests into pan-Arctic tundra ecosystems. It is unknown how the advance of beavers into Arctic watersheds will impact microbial communities responsible for the mineralization of organic matter (OM), which has implications for carbon cycling. To...

Harnessing Heterogeneity in Human Gut Microbiome Data

Creator:: Tataru, Christine
Abstract:: The focus of this thesis is to design, characterize, and apply novel computational methods and molecular systems to interrogate heterogeneous human gut microbiome-related phenomena. In Chapter 2, I design, implement, and characterize a method for embedding co-occurrence patterns derived from massive 16s amplicon datasets. I use this method to 1....

Intestinal Lesions and Parasites Associated with Senescence and Prespawn Mortality in Chinook Salmon (Oncorhynchus tshawytscha)

Creator:: Nervino, Stephanie A.
Abstract:: Pre-spawning mortality (PSM) presents a major problem for population recovery of spring Chinook salmon (Oncorhynchus tshawytscha) in the Willamette River basin. In certain reaches and years, PSM has exceeded 90%. Histology has been used as the primary diagnostic method to investigate PSM in the Chinook Salmon, and a collection of...

Expanding Diagnostic Assays for Pseudoloma neurophilia & Description of the Progression of Infection in Adult Zebrafish Populations

Creator:: Schuster, Corbin J.
Abstract:: Pseudoloma neurophilia is the most common pathogen reported in zebrafish (Danio rerio) research facilities and is an important threat to the zebrafish model. This microsporidian parasite can cause clinical disease, but more importantly is a causative agent of non-protocol induced variation in research. Studies utilizing infected zebrafish, could potentially confound...

Impacts of Environmental Change on a Newly-characterized Symbiosis between a Novel Bacterial Parasite, Genus Aquarickettsia, and the Coral Acropora cervicornis

Creator:: Klinges, J. Grace
Abstract:: Coral reef ecosystems continue to be significantly altered by disease epizootics, but why some host populations remain resistant while others succumb to outbreaks remains unknown. Research across diverse animal and plant host systems has revealed that disease severity is strongly influenced by host genetics and by environmental influences on both...

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...

The Effect of Protein Nitration on Cell Survival Pathways in Schwann Cells

Creator:: Graumann, Oliver W.
Abstract:: Neurofibromatosis type 2 (NF2) is a genetic disorder caused by the inactivation of the merlin tumor suppressor gene. NF2 patients develop bilateral vestibular schwannomas (VS) and other nervous system tumors with no effective drug treatment option. In pathological conditions, including NF2, production of the oxidant peroxynitrite leads to protein tyrosine...
