Physical and functional characterization of soluble protein antigen(s) produced by Renibacterium salmoninarum

Creator:: Turaga, Prasad S. D.
Abstract:: Renibacterium salmoninarum produces bacterial kidney disease (BKD) in salmonid fish. Soluble antigen(s) (SA) produced by the bacterium was characterized by physicochemical, functional and immunological methods. The molecular weight determination by SDS-PAGE analysis of SA yielded 14 different molecular weight species. Seven of these species were prominent, 57 kd protein being...

Coliphage T3 S-adenosylmethionine hydrolase : properties of the cloned gene and consequences of its expression in Escherichia coli

Creator:: Hughes, Jeffrey A.
Abstract:: To begin the development of a research tool for use in the in vivo study of S-adenosylmethionine (SAM) metabolism, I attempted to locate, isolate, clone and elicit the expression of the SAM hydrolase gene (E.C. 3.3.1.2) of the coliphage T3. The gene was isolated and cloned into the M13mp8 cloning...

Comparative genomics of Vibrio and characterizing microbial communities at a shellfish hatchery

Creator:: Delgado, Hanna
Abstract:: Vibrio bacteria are commonly found in freshwater, marine, and estuarine environments. Members of this genus can exist in commensal relationships with marine animals or as planktonic bacteria, however, they are well known for their roles as pathogens towards humans and animals. In this dissertation, I investigated aspects of host-bacteria relationships...

Distribution of Clostridium botulinum type E in fish, shellfish and the marine environment of the Pacific Northwest, and protein patterns of the toxigenic and non-toxigenic stains

Creator:: Craig, James Morrison
Abstract:: Interest in the distribution of Clostridium botulinum type E was heightened by the sudden outbreak of human botulism from smoked whitefish chubs and canned tuna fish in 1963. The question arose as to how widely the organism is distributed among fish and shellfish in the Northwest and what potential hazard...

Effects of Anthropogenic Stressors on Seagrass and Coral Microbiomes

Creator:: Wang, Lu
Abstract:: Seagrasses and coral reefs play important roles in nutrient cycling, coastal protection, and maintaining marine biodiversity. However, these coastal marine organisms are declining globally due to anthropogenic stressors, such as rising ocean temperatures, ocean acidification, and eutrophication. These organisms live in close association with their microbiomes, which can be beneficial...

The Oregon sockeye salmon virus (IHN) : A. Replication and autointerference. B. The effect of temperature on infection in Kokanee salmon (Oncorhynchus nerka) and on virus stability

Creator:: McAllister, Philip E.
Abstract:: Since the isolation of the Oregon sockeye salmon virus (OSV) in 1958, extensive investigations have been undertaken to characterize the properties of this virus. The results of these investigations have indicated that OSV is a single-stranded RNA virus which contains essential lipids and has a density of 1.16 gm/cm³ in...

Aeromonas salmonicida and aeromonas hydrophila (liquefaciens) as pathogens of salmonid fish. A. Selective aeromonas medium. B. Comparative characteristics of virulent and avirulent strains of aeromonas salmonicida. C. Effect of water temperature on aeromonas infections

Creator:: McCoy, Ralph Hines
Abstract:: Studies were directed toward the formulation of a selective Aeromonas medium that would permit the isolation of Aeromonas species in the presence of other common bacterial flora. The final composition of this medium, PBG Agar, in grams per liter, is: Bacto-peptone, 10; Bacto-beef extract, 10; glycogen, 4; NaCl, 5; sodium...

The Influence of Microbial Communities on Spatiotemporal Elemental Cycling in Coastal Margins Revealed by Community- and Population-level Genomics and Proteomics

Creator:: Kieft, Brandon P.
Abstract:: Biotic and abiotic processes at continent-ocean interfaces cycle a disproportionate mass of carbon and nutrients relative to their global surface area, and microbial activity is a principal determinant of organic and inorganic matter flux in these transition zones. Most studies using modern high-throughput ‘omics techniques to link microorganisms with costal...

Virulence factors of Aeromonas salmonicida and their interaction with the salmonid host

Creator:: Rockey, Daniel D.
Abstract:: Selected secreted and cellular virulence factors of Aeromonas salmonicida were examined. A protocol was developed for the separation of two secreted proteases (P1 and P2 protease), and a trout erythrocyte specific hemolysin (T-lysin) from supernatants of cultures of the bacterium. Distinctions between the proteases were demonstrated using molecular weight determinations,...

Biogeochemical Processing of Freshwater Carbon in the Anthropocene

Creator:: Buser, Jessica Z.
Abstract:: Freshwater systems cycle carbon along a spatial and temporal biogeochemical continuum, across which ecosystem processes contribute to transformations of organic matter (OM). Various ecological constraints impact rates OM transformation and production and consumption of the energetic end of respiration, methane. Microbiological processing and complete reduction of carbon substrates to methane...
