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...

Origin, incidence, and survival of Salmonella in a rural watershed

Creator:: Bolf, Ronald Bruce
Abstract:: A rural watershed containing a protected forest area in the north and a small rural community in the south was monitored for numbers of fecal indicator bacteria as well as the incidence and origin of the enteric pathogen Salmonella. Isolation of Salmonella only occurred once in the protected watershed, while...

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...

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...

Bactericidal and physico-chemical properties of a lectin derived from spring chinook salmon (Oncorhynchus tshawytscha) Ova

Creator:: Banowetz, Gary Michael
Abstract:: Unfertilized ova from spring chinook salmon (Oncorhynchus tshawytscha) were examined for the presence of classical salmonid inmmunoglobulin. Immunodiffusion techniques in which rabbit anti-salmonid immunoglobulin was reacted against an ova homogenate and rabbit anti-ova homogenate was reacted against immune chinook serum failed to detect classical-type antibodies within these eggs. A lectin...

Growth, survival, and antibiotic resistance transfer of Klebsiella in a botanical environment

Creator:: Yamamoto, Deborah Keiko
Abstract:: The ubiquitous presence of the coliform bacterium Klebsiella in botanical environments has been demonstrated. In this study, Klebsiella were found to multiply and colonize growing radish plants following contamination of seeds. All 29 cultures of Klebsiella tested from 5 different environments were capable of growth to 10⁶-10⁷ cells/gram of plant...

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...

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...

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....
