Impacts of multispecies parasitism on coho salmon (Oncorhynchus kisutch) in Oregon

Creator:: Ferguson, Jayde A.
Abstract:: Diseases caused by parasites are recognized as significant sources of mortality in wild fish populations. I assessed the impacts of multispecies parasitism on a threatened stock of juvenile coho salmon (Oncorhynchus kisutch). A crucial prerequisite to this research was proper identification of parasites, which can be difficult for species lacking...

Particulate Trace Metal Fluxes in the Western Arabian Sea and Their Links to Marine Productivity

Creator:: Flannery, Kelly M.
Abstract:: Many trace elements (e.g., Zn, Cd, Mo) are essential phytoplankton micronutrients, making them crucial to the marine ecosystem and ultimately the carbon cycle. Because of this association trace metals are also utilized in paleoceanographic studies (e.g., Mo, Cd). However, not much is known about what controls the cycling of these...

Differentiating freshwater contributions and their variability to the surface and halocline layers of the Arctic and subarctic seas

Creator:: Alkire, Matthew Buckley
Abstract:: Dramatic and ongoing changes pervading the Arctic and subarctic seas over recent decades have motivated this effort to track and better understand hydrographic variability using chemical tracers. Particular emphasis has been paid to differentiating freshwater contributions to upper layers: namely Pacific water, meteoric water, and sea-ice melt/formation. Data collected in...

Structural and functional analysis of the 57 kDa protein produced by the fish pathogen, Renibacterium salmoninarum

Creator:: Wiens, Gregory D.
Abstract:: Little is known about the virulence factors of Renibacterium salmoninarum, the causative agent of salmonid bacterial kidney disease. The predominant protein produced by R. salmoninarum in broth culture or during infection is a 57/58 kDa protein (p57) which is associated with strain virulence. In this study monoclonal antibodies (MAbs) to...

The role of Salmonella typhimurium type three secretion system (T3SS) and effector proteins in chromatophore cell response.

Creator:: Farhad, Mohammad
Abstract:: Bacterial contamination of food poses a great risk to human health worldwide. A chromatophore cell-based biosensor, utilizing B. splendens erythrophore cells, is an emerging technology that has shown potential to detect bacterial toxicity based on function-dependent mechanisms. Previous studies have investigated the response of erythrophore cells to foodborne pathogens, pesticides,...

Evaluation of zebrafish (Brachydanio rerio) as a model for carcinogenesis

Creator:: Tsai, Hsi-Wen
Abstract:: Zebrafish (Brachydanio rerio) are small, freshwater teleost fishes in the family Cyprinidae, the true minnows. They are native to the tropical latitudes of India, but have become widespread through their use as aquarium fish and as models for several branches of biological research. Their ease of rearing, short generation time,...

The conserved biology of herpesvirus latency : a study in cyprinid herpesvirus 3

Creator:: Reed, Aimee N.
Abstract:: Cyprinid herpesvirus 3 (CyHV-3), commonly known as koi herpesvirus (KHV), is a member of the Alloherpesviridae and is a deadly pathogen for koi and common carp, Cyprinus carpio. It causes severe gill necrosis and nephritis, dermal ulceration and hemorrhage, and mass mortality of up to 100% of affected fish. Fish...

Investigating the basis of substrate specificity in butane monooxygenase and chlorinated ethene toxicity in Pseudomonas butanovora

Creator:: Halsey, Kimberly H.
Abstract:: Pseudomonas butanovora, Mycobacterium vaccae, and Nocardioides sp. CF8 utilize distinctly different butane monooxygenases (BMOs) to initiate degradation of recalcitrant chlorinated ethenes (CEs) that pollute aquifers and soils. BMO-dependent degradation of CEs such as trichloroethylene (TCE) can lead to cellular toxicities. The type and severity of TCE transformation-dependent damage can have...

Functional, structural and evolutionary analyses of the ferritin-like superfamily of proteins

Creator:: Cooley, Richard Bleier
Abstract:: The ferritin-like superfamily (FLSF) of proteins is composed of a wide variety of functionally diverse proteins involved in oxygen dependent metal-mediated electron transfer reactions. Their biological importance is exemplified by the fact FLSF proteins are found in almost every organism from all three domains of life. Their functions range from...
