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...

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...

Intestinal Lesions and Parasites Associated with Senescence and Prespawn Mortality in Chinook Salmon (Oncorhynchus tshawytscha)

Creator:: Nervino, Stephanie A.
Abstract:: Pre-spawning mortality (PSM) presents a major problem for population recovery of spring Chinook salmon (Oncorhynchus tshawytscha) in the Willamette River basin. In certain reaches and years, PSM has exceeded 90%. Histology has been used as the primary diagnostic method to investigate PSM in the Chinook Salmon, and a collection of...

Disturbances in a marine bacterioplankton system drive community assembly towards niche-based processes

Creator:: Vergin, Kevin L.
Abstract:: Over 100 monthly bacterioplankton DNA samples, from each of the surface and 200 m depths at the Bermuda Atlantic Time-series Study (BATS) site, were analyzed for community assembly processes. Correlation networks, filtered for potential autocorrelation artifacts, were constructed for each depth. Network characteristics for the two depths were remarkably similar...

Microbial Community Dynamics of an Aquifer Biostimulated to Precipitate Calcite

Creator:: Ohan, Juliette
Abstract:: Microbial-induced calcite (CaCO₃) precipitation (MICP) is a well-known natural phenomenon where microbes precipitate calcite in their environment as a result of metabolic activity. It has recently been of interest as a bioengineered technique to stabilize soils for construction applications. A known metabolic pathway to induce MICP is ureolysis, where introduced...

Host-pathogen Interactions of Respiratory RNA Viruses and the Application of Recombinase Polymerase Amplification for Viral Diagnostics

Creator:: Prescott, Meagan A.
Abstract:: Humans and viral disease are inextricably intertwined. Viral disease plays an immeasurable role in human life, from the disease and economic burden associated with every facet of contending with human viral disease, to managing the consequences of viral disease in organisms important to our food supply, economy, and entertainment. The...

Genomic identification of candidate inclusion membrane proteins in Chlamydial species and microscopic analysis

Creator:: Blake, Nathanael A.
Abstract:: The Chlamydiaceae are a family of obligate intracellular bacteria with a unique biphasic developmental cycle. The replicating, metabolically active, intracellular phase bacteria (RBs) grow within a cellular vacuole know as the inclusion. Since the proteins the Chlamydiaceae secrete into this membrane are the means of host/parasite interaction, they have long...

High performance liquid chromatography of the staphylococcal enterotoxins

Creator:: Williams, Robert Roy
Abstract:: Many methods in use today for the isolation, purification, and identification of the staphylococcal enterotoxins involve lengthy steps with significant loss of enterotoxin, are subject to interference from contaminating sample components, and lack sufficient specificity. Culture extracts of enterotoxin producing Staphylococcus aureus strains (enterotoxins A-E), crude enterotoxin preparations (enterotoxins A-E),...

Molecular characterization of crustacean parasite Nadelspora canceri

Creator:: Amogan, Harold
Abstract:: Investigations into the phylogeny, genome size, and karyotype of microsporidian Nadeispora canceri were initiated to further characterize the organism. Isolates of N. canceri spores were obtained from both Dungeness (Cancer magisrer) and red rock crabs (Cancer productus). Analysis of the ssu rDNA sequence from spore isolates of the two crab...
