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.

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....
