Comparison of Flexibacter columnaris strains isolated from fish in North America and other areas of the Pacific Rim

Creator:: Song, Yen-ling
Abstract:: Twenty-two isolates of Flexibacter columnaris were collected from different species of fish from a wide geographic range. Shieh medium was selected and modified to provide satisfactory growth of F. columnaris strains. Although there were three phenotypic variations in colony morphology among the strains observed, the environmental and biochemical characteristics as...

Final report : environmental stresses and skeletal deformities in fish from the Willamette River, Oregon, USA

Creator:: Villeneuve, Daniel L., Curtis, Lawrence R., Jenkins, Jeffrey J., Warner, Kara E., Tilton, Fred A., Kent, Michael L., Watral, Virginia G., Cunningham, Michael E., Markle, Douglas F., Sethajintanin, Doolalai, Krissanakriangkrai, Oraphin, Johnson, Eugene R., Grove, Robert Allan, Anderson, Kim A., Oregon State University.

Department of Fisheries and Wildlife, and Institute for Natural Resources
Abstract:: The Willamette River, one of only 14 American Heritage Rivers, flows through the most densely populated and agriculturally productive region of Oregon. Previous biological monitoring of Willamette River fish detected elevated frequencies of skeletal deformities in fish from certain areas of the lower (NP [NP], rivermile [RM] 26-55) and middle...

Analysis of chlamydial and host proteins associated with infection

Creator:: Chu, Hencelyn
Abstract:: Chlamydiae are obligate intracellular bacteria that infect a variety of eukaryotic hosts and affect normal host processes. Within host cells, their developmental cycle takes place inside non-acidified vacuoles termed inclusions. An inclusion membrane composed primarily of secreted chlamydial synthesized proteins called Incs encloses the inclusion. At this location, Incs have...

The role of chlamydial inclusion membrane proteins in host-pathogen interaction and the development of novel methods for studying chlamydial biology

Creator:: Alzhanov, Damir T.
Abstract:: The majority of our modern understanding of bacterial pathogenesis is based on the strategy that involves screening bacterial genomes for the presence of the genes encoding pathogenic factors, and analysis of these genes via forward and reverse genetics. Chlamydiae represent a unique group of pathogenic bacteria in which it is...

Advances in Freshwater Cyanobacterial Genomics

Creator:: Brown, Nathaniel M.
Abstract:: Limnology is undergoing a transition to high-throughput -omic analysis of freshwater bacterial communities. An important first step in making the transition is to characterize several genomes that can be used as references to guide metagenome assembly and analysis. Here I characterize four new freshwater cyanobacterial genomes, a pair of lake...

Impacts of microbial chemical interactions on marine plankton physiology

Creator:: Moore, Eric R.
Abstract:: The bioavailability of chemical compounds in the marine environment fundamentally influences the growth and physiology of microorganisms. Organic and inorganic chemicals that are produced by some marine plankton can be consumed by other plankton for energy production, growth, or to initiate essential physiological processes. Cultures of the diatom Thalassiosira pseudonana,...

Comparison of Renibacterium salmoninarum by antigenic analysis, antimicrobial assay and growth

Creator:: Getchell, Rodman Guy
Abstract:: The antigens of eight isolates of Renibacterium salmoninarum were compared serologically using immunoelectrophoretic techniques. Seven common antigens were identified by their electrophoretic mobilities in each antigenic profile. One of these common antigens, designated Fr 21-30, was partially purified by ammonium sulfate precipitation and gel filtration. Cross adsorption analysis showed Fr...

Intestinal hyperplasia and neoplasms in zebrafish (Danio rerio)

Creator:: Paquette, Colleen Elizabeth
Abstract:: Zebrafish (Danio rerio) have become an increasingly important model organism for cancer research. There are several cancer models in which neoplasms are induced chemically or genetically. However, spontaneous (unknown etiology) neoplasms are rather common in zebrafish, particularly in older fish. For over a decade, spontaneous intestinal neoplasia and preneoplastic intestinal...

Growth and development of tetracycline resistant Chlamydia suis

Creator:: Lenart, Jennifer
Abstract:: Tetracycline is a front line antibiotic for the treatment of chlamydial infections in both humans and animals, and the emergence of tetracycline resistant (tet[superscript R]) Chlamydia is of significant clinical importance. Recently, several tet[superscript R] chlamydial strains have been isolated from swine (Sus scrofa) raised in production facilities in Nebraska....

Harnessing Heterogeneity in Human Gut Microbiome Data

Creator:: Tataru, Christine
Abstract:: The focus of this thesis is to design, characterize, and apply novel computational methods and molecular systems to interrogate heterogeneous human gut microbiome-related phenomena. In Chapter 2, I design, implement, and characterize a method for embedding co-occurrence patterns derived from massive 16s amplicon datasets. I use this method to 1....
