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....

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...

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...

Comparison of Flexibacter columnaris strains isolated from fish in North America and other areas of the Pacific Rim

Creator:: Song, Yen-ling
Abstract:: Twenty-two isolates of Flexibacter columnaris were collected from different species of fish from a wide geographic range. Shieh medium was selected and modified to provide satisfactory growth of F. columnaris strains. Although there were three phenotypic variations in colony morphology among the strains observed, the environmental and biochemical characteristics as...

Enteric Redmouth Bacterium of salmonids : a biochemical and serological comparison of selected isolates

Creator:: O'Leary, Patrick John
Abstract:: A comparison of the agglutinating and precipatiating antigens of Enteric Redmouth Bacterium (ERMB) was made. There are two major and one minor agglutinating antigens which describe two serotypes (I and II). Only serotype I metabolizes sorbitol. A bacterin from serotype I cross protected against a challenge of bacteria of serotype...

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...
