Glucocorticoid regulation of salmonid B lymphocytes

Creator:: Tripp, Ralph A.
Abstract:: The in vitro effects of cortisol in regulating salmonid B cell functions were investigated. B cells at three distinct stages of differentiation were examined for cortisol sensitivity. B lymphocyte responses were examined 1) during the early stage of the precursor, 2) during the intermediate stage of differentiation associated with clonal...

Bacterial pathogens and associated toxins involved in erythrophore cell aggregation

Creator:: Hutchison, Janine R.
Abstract:: Current detection methods for bacterial contamination rely on structure based detection of proteins and nucleic acids. While these methods are easy to use and reliable, they cannot evaluate the toxicity of a sample and the potential to cause disease. Previously, erythrophore cells derived from Betta splendens had been suggested as...

Single-Cell Genomics of Uncultivated Marine Bacteria

Creator:: Landry, Zachary
Abstract:: Historically, the difficulty of obtaining pure cultures of abundant marine microbial plankton has an obstacle to reconstructing the underlying mechanisms of biogeochemistry in the ocean. While a number of dominant marine species from the ocean surface have been cultured, the dominant microbial plankton of the dark ocean proved far more...

Chromatophores as cell-based biosensors for the detection of chemically and biologically toxic substances

Creator:: Dukovcic, Stephanie R.
Abstract:: Cell-based biosensors are function-based detectors that use the physiological response of a living cell to sense biologically stimulating agents. This emerging technology extends the application of current detection methods by reporting on the toxicity of a sample and the potential to cause disease. Previously, Betta splendens erythrophores have been described...

Delineation of the composition of an indigenous soil population of Rhizobium meliloti in root nodules of uninoculated field grown Medicago sativa L.

Creator:: Jenkins, Michael B.
Abstract:: Agronomic and microbiological studies were conducted on "Anchor" alfalfa (Medicago sativa L.) established from uninoculated seed on three Aridisols in central Oregon. Significant responses to 230 Kg N per ha (NH₄NO₃), which was applied in mid-April and after each first and second harvests, were observed in yield parameters of the...

Nutritional factors associated with the presence and growth of Klebsiella in redwood environments

Creator:: Talbot, Henry Wilkinson
Abstract:: Bacteria of the genus Klebsiella have been found to be associated with redwood water storage reservoirs, redwood chips, and liquid expressed from within living redwood. A 1,000 gallon experimental redwood reservoir was employed to determine how to control the presence of Klebsiella and Enterobacter in drinking water stored in these...

The effect and metabolism of 5'-methylthioadenosine in normal and 5'-methylthioadenosine phosphorylase deficient mammalian cells

Characterization of Mycobacterium avium subsp. hominissuis Interactions with Host Macrophages and Multinucleated Giant Cells

Creator:: Joseph, Jayanthi J.
Abstract:: To examine the macrophage response to M. avium, I compared inflammasome and cytosolic sensor expression and activation. My result demonstrated that virulent strains of M. avium (A5 and 104) suppress IL-1β production and induce IFN-β production in macrophages. M. avium mutants deficient at DNA export in the biofilm exhibited reduced...

Methods for the in vitro cultivation of cells from the tissues of salmonid fishes

Creator:: Fryer, John L.
Abstract:: Methods examined for the preparation of cells from tissues of salmonid fishes for primary cultivation were the fragment (explant) and enzyme dispersion techniques. Both methods were employed for the cultivation of a variety of tissues from Pacific salmon, Oncorhynchus spp., and the steelhead trout, Salmo gairdneri gairdneri. A technique was...

Distribution of Clostridium botulinum type E in fish, shellfish and the marine environment of the Pacific Northwest, and protein patterns of the toxigenic and non-toxigenic stains

Creator:: Craig, James Morrison
Abstract:: Interest in the distribution of Clostridium botulinum type E was heightened by the sudden outbreak of human botulism from smoked whitefish chubs and canned tuna fish in 1963. The question arose as to how widely the organism is distributed among fish and shellfish in the Northwest and what potential hazard...
