  • 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 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...

  • 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....

  • Comparison of Renibacterium salmoninarum by antigenic analysis, antimicrobial assay and growth

    Creator:
    Getchell, Rodman Guy
    Abstract:
    The antigens of eight isolates of Renibacterium salmoninarum were compared serologically using immunoelectrophoretic techniques. Seven common antigens were identified by their electrophoretic mobilities in each antigenic profile. One of these common antigens, designated Fr 21-30, was partially purified by ammonium sulfate precipitation and gel filtration. Cross adsorption analysis showed Fr...

  • 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...

  • Isolation and characterization of a leukocytolytic factor from Aeromonas salmonicida

    Creator:
    Fuller, David Wallace
    Abstract:
    The purpose of this study was to find what effect temperature and immunization has on the phagocytic activity of fish leukocytes against certain disease causing bacteria. Also proposed was the isolation and characterization of a leukocytolytic factor produced by one of these bacteria, Aeromonas salmonicida. Investigations revealed that temperature had...

  • 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...

  • 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...
