Impacts of Environmental Change on a Newly-characterized Symbiosis between a Novel Bacterial Parasite, Genus Aquarickettsia, and the Coral Acropora cervicornis

Creator:: Klinges, J. Grace
Abstract:: Coral reef ecosystems continue to be significantly altered by disease epizootics, but why some host populations remain resistant while others succumb to outbreaks remains unknown. Research across diverse animal and plant host systems has revealed that disease severity is strongly influenced by host genetics and by environmental influences on both...

Expanding Diagnostic Assays for Pseudoloma neurophilia & Description of the Progression of Infection in Adult Zebrafish Populations

Creator:: Schuster, Corbin J.
Abstract:: Pseudoloma neurophilia is the most common pathogen reported in zebrafish (Danio rerio) research facilities and is an important threat to the zebrafish model. This microsporidian parasite can cause clinical disease, but more importantly is a causative agent of non-protocol induced variation in research. Studies utilizing infected zebrafish, could potentially confound...

Multiple Stressors Drive Changes in Coral Microbiome Diversity and Composition Demonstrating the Role of a Bacterial Symbiont in Microbial Community Sensitivity and Resilience

Creator:: Maher, Rebecca L.
Abstract:: On coral reefs, disturbances rarely occur in isolation. Global stressors such as increasing seawater temperature often coincide with local stressors like nutrient pollution. In the face of increasing anthropogenic stress, corals can function as environmental sentinels, although little is known about how multiple stressors interact to disrupt their associated bacterial...

B-cell heterogeneity in salmonids

Creator:: Irwin, Michael J.
Abstract:: Salmonid B lymphocytes were stimulated both in vivo and in vitro and shown to produce antibody specific for the immunogen. A passive hemolytic plaque assay was employed to demonstrate B cells producing specific antibody. Characterization of plaque forming cells (PFCs) involved sequential inhibition with a series of graded concentrations of...

In vitro regulation and cultivation of salmonid lymphocytes

Creator:: DeKoning-Loo, Jenefer
Abstract:: The foundation of the research compilation presented here began with the derivation of an improved method for obtaining optimal in vitro mitogenic responses in salmonid lymphocyte cultures by utilizing autologous or homologous plasma as the primary serum supplement. It was observed that lymphocytes which were previously unresponsive to mitogenic challenge...

Infection and immune response induced by Vibrio anguillarum in juvenile coho salmon (Oncorhynchus kisutch)

Creator:: Groberg, Warren J.
Abstract:: Immunity in juvenile coho salmon (Oncorhynchus kisutch) was evaluated after immunization against vibriosis by parenteral, oral or immersion methods. Relative levels of immunity were determined by protection of fish from experimental water-borne challenges with Vibrio anguillarum and by serum agglutination titers. Coho salmon eggs were exposed to bacterin during artificial...

The Evolution of Scleractinian Microbial Symbionts

Creator:: McMinds, Ryan C.
Abstract:: The modern world has presented many threats to the health and stability of ecosystems worldwide. One of the most biodiverse ecosystems, coral reefs, faces particularly strong pressures, and is already declining rapidly in complexity and area. Although the stressors that affect reefs are diverse, ranging from nutrient pollution to overfishing,...

Structural and functional analysis of the 57 kDa protein produced by the fish pathogen, Renibacterium salmoninarum

Creator:: Wiens, Gregory D.
Abstract:: Little is known about the virulence factors of Renibacterium salmoninarum, the causative agent of salmonid bacterial kidney disease. The predominant protein produced by R. salmoninarum in broth culture or during infection is a 57/58 kDa protein (p57) which is associated with strain virulence. In this study monoclonal antibodies (MAbs) to...

Transformation of alfalfa using Agrobacterium tumefaciens

Creator:: Gelford, Inga L.
Abstract:: Agrobacterium tumefaciens, the causative agent of crown gall disease, does not readily infect commercial varieties of alfalfa (Medicago sativa). Cloned virulence genes from the megaplasmid pTiBo542 have been shown to enhance Agrobacterium host range and infectivity on dicotyledonous plants. To obtain a gene transfer system for commercial alfalfa cultivars, an...
