Interactions Between Aquatic Chromogenic Bacteria And Pathogenic Vibrio Spp., John Louis Harris
Biological Sciences Theses & Dissertations
Interactions between populations inhabiting an ecosystem are responsible, in large part, for determining which species coexist in that ecosystem. In this study, interactions between selected Vibrio species, V. alginolyticus and V. anguillarum, and marine heterotrophic, chromogenic bacteria in aquatic microcosms were investigated. The ultimate goal of this project was to evaluate the feasibility of ex ploiting competitive interactions as a means to biologically control growth of the pathogenic marine bacteria, V. alginolyticus and V. anguillarum. In the majority of experiments (14/16), if chromogenic species were allowed to develop stable populations before a Vibrio spp. was introduced into a …
Effects Of Corticosteroids And Of Cyclosporin A On Trypanosoma Musculi In Mice And In Culture, Philip Stephen Schuyler
Effects Of Corticosteroids And Of Cyclosporin A On Trypanosoma Musculi In Mice And In Culture, Philip Stephen Schuyler
Loma Linda University Electronic Theses, Dissertations & Projects
The in vivo and in vitro effects of cyclosporin A and corticosteroids on Trypanosoma musculi were examined. Mice that received continuous administration of 6 mg/liter/day of dexamethasone in drinking water and 200 mg/kg hydrocortisone acetate as a single dose 24 hrs prior to injection with T. musculi had significantly higher and longer parasitemias, than controls. Body and spleen weights and B cell responsiveness were lower in test animals and there were some deaths. Mice injected with T. musculi that received 100 mg/kg/day cyclosporin A had longer, but not higher, parasitemias than controls. Corticosteroids appear to partially inactive antibody production (i.e. …
