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...

Isolation and characterization of a new reovirus from chum salmon (Oncorhynchus keta)

Creator:: Winton, James R.
Abstract:: This report describes the isolation of a new virus from adult chum salmon (Oncorhynchus keta) returning to the Tokushibetsu Hatchery, Hokkaido, Japan. The agent was isolated in the CHSE-214 cell line derived from chinook salmon (Oncorhynchus tshawytscha). The virus replicated in selected fish cell lines incubated between 10 and 20°C...

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...

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...

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...

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...

Yersinia ruckeri : a characterization of the carrier state in steelhead trout (Salmo gairdneri)

Creator:: Hunter, Valerie Antoinette
Abstract:: Fish, asymptomatically infected with Enteric Redmouth Bacterium (ERMB), were tested for their ability to transmit bacteria to non-infected fish. Unstressed carrier fish were unable to transmit enough bacteria to cause epizootics or produce carrier fish. However, when the ERMB carriers were stressed with heat, sufficient bacteria were shed to infect...

Certain chemical and immunological properties of the endotoxin from Vibrio anguillarum

Creator:: Abe, Patrick Masami
Abstract:: The Boivin agent from Vibrio anguillarum was extracted with the use of 0.25M trichloroacetic acid (TCA). Chemical analysis revealed that the endotoxin contained approximately 35.1% protein, 18.1% carbohydrate, 39.3% lipid, 1.8% glucosamine and evidence of ethanolamine. Sixteen different amino acids made up the protein. The aliphatic amino acid concentration was...

The antibody response of juvenile coho salmon (Oncorhynchus kisutch) to Aeromonas salmonicida, the causative agent of furunculosis

Creator:: Paterson, William Douglas
Abstract:: This research was initiated to investigate the effects of various parameters on the immune response of juvenile coho salmon to Aeromonas salmonicida. The antibody response and development of protective immunity in juvenile coho salmon were followed after a single intraperitoneal injection of formalin killed A. salmonicida cells emulsified in Freund's...

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...
