Fecal Bacteroidetes host distributions and environmental source tracking

Creator:: Dick, Linda K.
Abstract:: Contamination of recreational and shellfish waters with fecal pollution is a major water quality issue with associated economic impacts and human health risks. Reliable fecal source identification and rapid, quantitative analyses are essential components of risk assessment. Enteric bacteria that are endemic to specific hosts have a potential role as...

Pathogenic and molecular characterization of three closely related isolates of infectious pancreatic necrosis virus (IPNV)

Creator:: Bruslind, Linda D.
Abstract:: Three closely related isolates belonging to the A₁ serotype of infectious pancreatic necrosis virus (IPNV) were selected for comparison, to provide insight into the nature of variation in the virulence of IPN viruses. Brook trout fry (Salvelinus fontinalis) were experimentally infected with the three isolates by immersion. Cumulative mortalities over...

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...
Resource Type:: Dissertation
Full Text:: antiporter was found to be a K+(Na+)/H+ antiporter essential for V. cholerae growth at low environmental pH

Anaerobic biodegradation of the cyclic nitramines, RDX and HMX, by ovine ruminal microbes

Creator:: Eaton, Hillary L.
Abstract:: Cyclic nitramines released into all environmental compartments through anthropogenic activities are toxic and possibly carcinogenic and mutagenic. Soils on military ranges, located throughout the world in various climatic regions and close to human activities, are especially susceptible to cyclic nitramine contamination. The properties of soils on military ranges will directly...

Survival and persistence of Bacteroidales human and ruminant specific fecal markers and occurrence with fecal pathogens

Creator:: Walters, Sarah P.
Abstract:: Aquatic fecal contamination from non-point sources impairs environmental health and serves as a vehicle for transmission of waterborne disease, resulting in economic losses worldwide. Accurate methods of diagnosing fecal pollution and its source are needed to prevent human exposure, remediate pollution, and reduce economic impacts. In order to obtain this...

Characteristics of two salmonid fish cell lines : glycolytic rates, CO₂ requirements and susceptibility to Reovirus and Reovirus-like agents

Creator:: Kleeman, Karl Terrence
Abstract:: The research presented in this thesis is concerned with the characterization of two salmonid cell lines, CSE 119 derived from embryos of coho salmon (Oncorhynchus kisutch) and STE 137 derived from embryos of steelhead trout (Salmo gairdneri). The rates of glucose utilization and lactic acid production during the most active...

Investigations of regulatory T cell induction by 2, 3, 7, 8-Tetrachlorodibenzo-p-dioxin during a graft-versus-host response

Creator:: Marshall, Nikki B.
Abstract:: The immune toxicity of 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) has been studied for over 35 years, but only recently has the profound immune suppression associated with TCDD exposure been linked to induction of regulatory T cells (Tregs). The effects of TCDD are mediated through binding the aryl hydrocarbon receptor (AhR), a ligand-activated transcription...

Ruminal Biodegradation of Heterocyclic Toxic Compounds

Creator:: Tanaree, Dan D.
Abstract:: Cyclic nitramines are a class of compounds that include most of the commonly used explosives today. These are among the most common toxicants released into the environment as a result of human activity, generated on military ranges, battlefields, and production sites. Of these, hexahydro-1,3,5-trinitro-1,3,5- triazine (RDX) is of particular interest,...

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...
