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...

Occurrence of the protozoan fish parasite Ceratomyxa shasta in the Deschutes River basin and the ultrastructure of the spore

Creator:: Gould, Rowan Wayne
Abstract:: The purpose of this paper was twofold, (1) to determine the distribution of the infective stage of Ceratomyxa shasta (Noble) in the Deschutes River basin, and (2) to study the ultrastructure of the spore stage of the protozoan parasite. Liveboxes containing juvenile rainbow trout were placed at specific test points...

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...

A study of corynebacterial kidney disease of salmonid fishes

Creator:: Rowse-Eagle, Debra H.
Abstract:: This study was undertaken to compile a comprehensive review of the literature and to gain a better understanding of the host-parasite relationship in corynebacterial kidney disease of salmonid fishes. An indirect fluorescent antibody technique was developed which allowed differentiation of intra- and extracellular bacteria. This technique was used in combination...

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...

Development of a new vaccine delivery system for immunizing fish and investigation of the protective antigens in Vibrio anguillarum

Creator:: Gould, Rowan Wayne
Abstract:: Phenol-water and trichloroacetic acid extracts of Vibrio anguillarum were both antigenic and immunogenic when injected into coho salmon (Oncorhynchus kisutch). Cross-protection against virulent Vibrio anguillarum was observed with whole-cell bacterins and phenol-water extracts prepared from two serologically distinct groups. Gel diffusion studies indicated that intact somatic antigens were serotype specific....

Oral immunization for possible control of furunculosis in fish

Creator:: Frost, Gary Douglas
Abstract:: This project was initiated in an attempt to control furunculosis (Aeromonas salmonicida) in a production hatchery rearing coho salmon. An oral vaccine was prepared and administered to 520,000 juvenile coho salmon (Oncorhynchus kisutch) at the Siletz River Salmon Hatchery prior to the onset of a predictable naturally occurring epizootic of...

Properties of anti- Aeromonas salmonicida antibodies from juvenile coho salmon (Oncorhynchus kisutch)

Creator:: Cisar, John Ormond
Abstract:: After parenteral immunization with Aeromonas salmonicida cells, the agglutination activity in juvenile coho salmon (Oncorhynchus kisutch) serum was associated with the macroglobulin serum fraction. Antibody activity was diminished by 30 minutes exposure to 50 C but not 45 C. Reduction with 2-mercaptoethanol and alkylation markedly lowered but did not completely...

Pathogenic, antigenic, and immunogenic properties of Aeromonas salmonicida studied in juvenile coho salmon (Oncorhynchus kisutch)

Creator:: Udey, Lanny R.
Abstract:: An additional layer, exterior to the outer membrane cellwall layer, was found on Aeromonas salmonicida cells from aggregating strains. Nonaggregating strains were found to lack this layer. The nonaggregating strains were all avirulent (LD₅₀ greater than 1 X 10 ⁸ CFU/fish) while the majority of the aggregating strains were virulent...
