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...

Developing a system of mutagenesis in Francisella tularensis LVS

Creator:: Flax, Lindsay A.
Abstract:: Francisella tularensis is a gram-negative facultative intracellular coccobacillus that primarily infects macrophages. The causative agent of tularemia, this bacterium is considered among the most infectious organisms known, requiring fewer than ten organisms to cause disease. Although ubiquitous in nature, transmission to humans is rare but can occur via insect bites,...

The role of S-adenosylmethionine in the biosynthesis of ergosterol and related sterols in Saccharomyces cerevisiae

Creator:: Turner, Jan Ross
Abstract:: An enzyme system was prepared from Saccharomyces cerevisiae, strain MCC, which carries out the transfer of the methyl group from S-adenosylmethionine or methionine to the side chain of yeast sterols. The cell-free system has been shown to be incapable of synthesizing ergosterol but carries out the synthesis of two as...

Novel Experimental Designs and Mathematical Models to Study Fecal Indicator Bacteria Persistence in Surface Water

Creator:: Brooks, Lauren
Abstract:: High counts of fecal indicators, used to signal the potential presence of pathogens associated with untreated waste, result in the classification of water bodies throughout the United States as impaired. Nonpoint sources of unknown origin that contribute to fecal contamination make management of impaired waters challenging, as they are difficult...

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...

Survival of fecal coliform bacteria in sludge-amended soils

Creator:: Hartel, Peter G.
Abstract:: A study was conducted to determine the effects or temperature, solar radiation, rainfall, and saturated flow on fecal coliform numbers in sewage sludge-amended soils. To determine this, four 4.6 X 13.7 m field plots were each amended in summer and in winter with 800 liters of anaerobically-digested sewage sludge, and...

Properties of the Glycoprotein of infectious hematopoietic necrosis virus

Creator:: Engelking, Henry Mark
Abstract:: The glycoprotein, G, of infectious hematopoietic necrosis virus, IHNV, was shown to be the viral protein which elicits and reacts with neutralizing antibodies. The G protein also confers protective immunity on immunized susceptible salmonid hosts to IHNV. The other three structural proteins of IHNV, N, Ml, and M2, do not...

Differential decay of human faecal Bacteroides in marine and freshwater

Creator:: Green, Hyatt C., Shanks, Orin C., Sivaganesan, Mano, Haugland, Richard A., and Field, Katharine G.
Abstract:: Genetic markers from Bacteroides and other faecal bacteria are being tested for inclusion in regulations to quantify aquatic faecal contamination and estimate public health risk. For the method to be used quantitatively across environments, persistence and decay of markers must be understood. We measured concentrations of contaminant molecular markers targeting...

Comparison of fixatives and fixation time for PCR detection of Mycobacterium in zebrafish Danio rerio

Creator:: Peterson, Tracy S., Kent, Michael L., Ferguson, Jayde A., Watral, Virginia G., and Whipps, Christopher M.
Abstract:: Mycobacteriosis is a common disease of laboratory zebrafish Danio rerio. Different infection patterns occur in zebrafish depending on mycobacterial species. Mycobacterium marinum and M. haemophilum produce virulent infections associated with high mortality, whereas M. chelonae is more widespread and is not associated with high mortality. Identification of mycobacterial infections to...
