Molecular and genetic assessment of selected antiporters and methyl-accepting chemotaxis proteins in Vibrio cholerae

Creator:: Quinn, Matthew J.
Abstract:: The pathogen Vibrio cholerae uses cations as a primary currency of virulence and environmental persistence, using gradients of those cations to move, acquire nutrients, and control virulence gene expression. An understanding of the overlapping roles of bioenergetics and chemotaxis in the virulence and environmental survival of V. cholerae issues from...

Characterization of the Na⁺-transporting NADH:ubiquinone oxidoreductase (NQR) in Vibrio cholerae

Creator:: Fassio, Sara R., Minato, Yusuke, Quinn, Matthew J., Faulkner, Wyatt J., and Hase, Claudia C.
Abstract:: We previously reported that inhibition of the Na⁺ translocating NADH:ubiquinone oxidoreductase (NQR), either by chemical inhibition or mutation, increased toxT transcription in Vibrio cholerae. In this study, we revealed that the nqr mutant strain showed similar phenotypes as the Escherichia coli NADH dehydrogenase I (nuo) mutant strain (e.g. growth defect...

The biosynthesis of ethylene from methionine in Saccharomyces cerevisiae

Creator:: Jones, Paul Aikens
Abstract:: Methionine metabolism, leading to the biosynthesis of ethylene in Saccharomyces cerevisiae does not appear to involve S-adenosylmethionine (SAM) and aminocyclopropanecarboxylic acid (ACC), based on the lack of ethylene synthesis when both SAM and ACC were incubated in the presence and absence of cells. Thus, the mechanism leading to the formation...

Genome-enabled investigation of the minimal growth requirements andphosphate metabolism for Pelagibacter marine bacteria

Creator:: Carini, Paul J.
Abstract:: Members of the SAR11 clade of heterotrophic α-proteobacteria are ubiquitous and abundant in the world's oceans where they are thought to play a pivotal role in the global carbon cycle. The first SAR11 bacterium cultivated in vitro, 'Candidatus Pelagibacter ubique' HTCC1062 (Ca. P. ubique), was isolated by dilution into sterile...

Chlamydiae under stress : environmental conditions influence the production and localization of chlamydial antigens

Creator:: Brown, Wendy J.
Abstract:: Chlamydiae are obligate intracellular pathogens that cause several serious conditions within the human host. Many of the symptoms associated with infection are thought to stem from the development of aberrant, or persistent, chlamydiae. Factors leading to chlamydial persistence include deprivation of amino acids, the release of certain cellular factors, or...

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...

Assessing disease impacts of hatcheries on downstream salmonids in the Willamette River Basin, Oregon

Creator:: Jakaitis, Michelle
Abstract:: Hatcheries are often perceived as a source of pathogen amplification, potentially increasing disease risk to free-ranging populations; at the same time, free-ranging fishes may introduce pathogens into hatcheries through untreated water sources. Many pathogens exist naturally within the environment (with the exception of introduced pathogens) and the presence of a...

Chemical and Genetic Investigations of Toxic Freshwater Cyanobacterial Blooms for Improved Monitoring and Understanding of Lake Ecology

Creator:: Collart, Lindsay P.
Abstract:: Toxin production by cyanobacterial harmful algal blooms (cyanoHABs) in freshwater systems has lasting ecological and human impacts. Nutrients, light availability, hydrology, and microbial community composition impact the frequency and intensity of toxic cyanoHABs. Climate change will exacerbate toxic cyanoHABs, making real time and predictive monitoring a vital tool for managing...
