Occurrence of the protozoan parasite Ceratomyxa shasta among salmonid fishes in Oregon waters

Creator:: Sanders, James Edward
Abstract:: This project was initiated to determine the incidence, distribution and species of fish affected by Ceratomyxa shasta in Oregon waters. Returning adult Pacific salmon and steelhead trout were chosen for the survey because they were known to be susceptible to infection. The parasite was also believed to be an important...

Control of furunculosis in Pacific salmon by immunization

Creator:: Overholser, Donald Lee
Abstract:: The purpose of this project was to study the possibility of controlling furunculosis in salmonid fish using immunological procedures. Antiserum with an agglutinating antibody titer of 1:20,480 against Aeromonas salmonicida was produced in a horse. This hyperimmune serum was used to passively immunize coho salmon, Oncorhynchus kitsutch, (jacks). However, this...

Certain aspects of the immunology and chemotherapy of bacterial kidney disease in juvenile coho salmon (Oncorhynchus kisutch)

Creator:: Banowetz, Gary Michael
Abstract:: The detection and antigenic nature of the causative Corynebacterium of bacterial kidney disease and chemotherapy of this disease in juvenile coho salmon (Oncorhynchus kisutch) were examined. Each of 207 yearling coho salmon collected from a population undergoing a severe epizootic of bacterial kidney disease were examined for the presence of...

Oral immunization for the control of vibriosis in Pacific salmon

Creator:: Nelson, Jim Steel
Abstract:: An oral vaccine was developed for control of vibriosis in Pacific salmon. The vaccine consists of a lyophilized sonicate of cells of Vibrio anguillarum, the causative agent of this disease. The preparation was incorporated into a ration and fed to salmon in fresh water before the fish were transported and...

Immune responses of salmonids : a) Oral immunization against Flexibacter columnaris : b) Effects of combining antigens in parenterally administered polyvalent vaccines

Creator:: Ransom, David Peter
Abstract:: Juvenile coho salmon (Oncorhynchus kisutch) were orally immunized against the bacterium Flexibacter columnaris (formerly Chondrococcus columnaris), the causative agent of columnaris disease in fish, with a vaccine-food preparation containing formalin-killed cells. Fish immunized for 1, 2, 3, and 4 months were challenged with selected concentrations of F. columnaris by exposure...

Oral and parenteral immunization for the control of Vibrio anguillarum, the etiological agent of vibriosis in salmonid fish

Creator:: Rohovec, J. S.
Abstract:: Efficacious vaccines were developed for the control of Vibrio anguillarum, the etiological agent of vibriosis in salmonid fish. These bacterins can be administered either orally or parenterally. It was determined that both formalin-killed lyophilized whole cells and wet-packed whole cells of the organism are effective oral immunogens. Intraperitoneal injection of...

Distribution and epizootiology of infectious pancreatic necrosis and infectious hematopoietic necrosis of salmonid fishes in Oregon

Creator:: Mulcahy, Daniel M.
Abstract:: The distribution in Oregon of two viruses affecting salmonid fishes was determined by examination of hatchery and feral fish. Infectious pancreatic necrosis virus (IPNV) was isolated from fish at the Oregon Department of Fish and Wildlife Research Laboratory, Corvallis, Roaring River, Fort Klamath, and Wizard Falls Hatcheries. Fish collected at...

Cell wall chemistry, deoxyribonucleic acid base composition and pathogenesis of the kidney disease bacterium in salmonid fishes

Creator:: Sanders, James Edward
Abstract:: Experiments were designed to more precisely evaluate the effects of water temperature on the progress of bacterial kidney disease ( BKD) in three species of salmonid fishes. Infections were produced by intraperitoneal injection of suspensions of the causative organism into fish held at seven temperatures ranging from 3.9 to 20.5°C....

Bacteriologic, immunologic and pathogenic studies of Vibrio spp. pathologic to salmonids

Creator:: Ransom, David Peter
Abstract:: Fish diseases and various parameters associated with disease caused mortality of fish were monitored at the Oregon State University Marine Science Center and at a private mariculture facility on Yaquina Bay during a period of five years. Nearly all disease problems observed were caused by Vibrio anguillarum and Vibrio spp....

Relative resistance of the Coho salmon (Oncorhynchus kisutch) and the Chinook salmon (Oncorhynchus tshawytscha) to the parasitic larvae (Glochidia) of the freshwater mussel (Margaritifera margaritifera)

Creator:: Fustish, Charles A.
Abstract:: The relative resistance of the coho salmon (Oncorhynchus kisutch) and the chinook salmon (O. tshawyscha) to the parasitic larvae (glochidia) of the freshwater mussel (Margaritifera margaritifera) was studied in an attempt to determine why the coho appeared to be more resistant. Natural and acquired antibody was sought in the mucus...
