The Role of the Mucosal Immunoglobulin IgT and Inflammatory Cytokines in Ceratonova shasta Infections in Rainbow Trout

Creator:: Taggart-Murphy, Laura M.
Abstract:: The myxozoan parasite Ceratonova shasta threatens both juvenile and adult salmonid populations in the Pacific Northwest region of the United States, causing intestine necrosis and hemorrhaging, along with high mortality in some fish strains. It induces an inflammatory tissue response in susceptible strains of fish; understanding the interactions between C....

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...

Studies on the lipid and fatty acid composition of Micrococcus radiodurans

Creator:: Lewis, Norman Francis
Abstract:: Comparatively little work has been done on bacterial lipids. There are profound differences between bacterial lipids in general and lipids of the higher forms of life in such respects as the absence of sterols, phospholipids low in nitrogen but high in inositol and carbohydrate, the presence of large proportions of...

Gamma irradiation patterns of Salmonella typhosa, Salmonella paratyphi B, and Salmonella wichita in crabmeat

Creator:: Dyer, John Kaye
Abstract:: Studies were conducted under controlled conditions in order to observe the resulting survival patterns in solid crabmeat of Salmonella typhosa, Salmonella paratyphi B, and SaImonella wichita following individual exposure to various doses of gamma radiation. As shown in their survival curves, these species of Salmonella exhibited in varying degrees a...

Significance of pigments in radiation resistance of Micrococcus radiodurans

Creator:: Krabbenhoft, Kenneth Louis
Abstract:: An ecological study of a microorganism similar to that isolated in 1956 and designated as Micrococcus radiodurans indicated that the organism could be isolated from several different environments. By taking advantage of its radio-resistivity, high levels of gamma radiation were used in the isolation procedures to inactivate most of the...

Bactericidal and physico-chemical properties of a lectin derived from spring chinook salmon (Oncorhynchus tshawytscha) Ova

Creator:: Banowetz, Gary Michael
Abstract:: Unfertilized ova from spring chinook salmon (Oncorhynchus tshawytscha) were examined for the presence of classical salmonid inmmunoglobulin. Immunodiffusion techniques in which rabbit anti-salmonid immunoglobulin was reacted against an ova homogenate and rabbit anti-ova homogenate was reacted against immune chinook serum failed to detect classical-type antibodies within these eggs. A lectin...

B-cell heterogeneity in salmonids

Creator:: Irwin, Michael J.
Abstract:: Salmonid B lymphocytes were stimulated both in vivo and in vitro and shown to produce antibody specific for the immunogen. A passive hemolytic plaque assay was employed to demonstrate B cells producing specific antibody. Characterization of plaque forming cells (PFCs) involved sequential inhibition with a series of graded concentrations of...

Pseudoloma neurophilia : progression of infection and transmission characteristics of a microsporidian parasite in a model vertebrate, Danio rerio

Creator:: Sanders, Justin L.
Abstract:: The microsporidian parasite, Pseudoloma neurophilia, is the most commonly diagnosed infectious disease in laboratory populations of the zebrafish, Danio rerio. Infections by P. neurophilia are generally subclinical, however, they can become acute either incidentally or due to experimental immune suppression. Non-protocol induced variation can confound results in laboratory experiments using...

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...

The effects of commercial rhizobium inoculants on the establishment of Trifolium subterraneum in southwest Oregon soils

Creator:: Jenkins, Michael B.
Abstract:: Commercial inoculant products for subclover that are marketed in the Pacific Northwest were evaluated in field trials (supplemented by appropriate laboratory analysis) at four sites in southwest Oregon. The materials tested were Nitragin (Milwaukee, WI) and Northrup-King (Minneapolis, MN) peat-based inocula, and Celpril (Manteca, CA) inoculated, lime-pelleted subclover seed. Duplicate...
