Variability in Plant Growth Promoting Properties Among Clinical and Environmental Isolates of Stenotrophomonas Maltophilia
(North Dakota State University, 2015)
Stenotrophomonas maltophilia has both negative and positive attributes by being a human pathogen and plant growth promoting rhizobacterium. This study sought to determine if environmental and clinical isolates of S. ...
Brucellosis Epidemiology, Virulence Factors, Control and Molecular Targets to Prevent Bacterial Infectious Diseases
(North Dakota State University, 2012)
Brucellosis is a bacterial zoonosis that infects both professional phagocytic and nonphagocytic cells in the hosts. Brucella intracellular survival is important for its virulence. In a study to establish the seroprevalence ...
Genetic Disruption of VIP Signaling Alters Intestinal Microbial Structure and Immunity
(North Dakota State University, 2018)
Vasoactive intestinal peptide (VIP) regulates clock gene expression in the brain that synchronizes diurnal feeding behaviors in mammals. In the gastrointestinal (GI) tissues, VIP influences host nutrient absorption from ...
Glycan Triggers of Life Cycle Development in the Apicomplexan Parasite Cryptosporidium
(North Dakota State University, 2017)
Cryptosporidium is an apicomplexan parasite that causes the diarrheal disease cryptosporidiosis, an infection that can become chronic and life threating in immunocompromised and malnourished individuals. Development of ...
Heterogeneity in Phenotypic Response of Foodborne Pathogens to Control Measures
(North Dakota State University, 2019)
Foodborne pathogens are estimated to cause 48 million foodborne illnesses through consumption of contaminated food annually. Designing efficient control measures is vital to reducing foodborne illnesses. The modern trend ...
Investigations in Asthma Heterogeneity: The Roles of Aspergillus Fumigatus-Derived Eicosanoid Synthases and Occupational Exposures to Grain Dusts on the Development of Fungal Allergic Asthma
(North Dakota State University, 2013)
Allergic asthma is an inflammatory syndrome of the respiratory system which changes the airway wall architecture. Using an aeroallergen, murine model of A. fumigatus-mediated asthma, the two studies herein examine the ...
Biofilm Formation of Escherichia coli from Surface Soils is Influenced by Variation in Cell Envelope, Iron Metabolism, and Attachment Factor Genes
(North Dakota State University, 2018)
Biofilm formation may increase survival and persistence of Escherichia coli in the highly variable conditions of soil environments, though it remains unknown the extent variation in biofilm formation affects survival. We ...
Gene Expression and Evolution in Escherichia Coli Biofilm
(North Dakota State University, 2014)
Biofilms can be defined as a complex aggregation of bacterial communities that involves many gene regulatory mechanisms, as well as evolutionary processes to increase biodiversity. Specific Aim 1 used a gene regulation ...
Happy Beef: The Development of ß-Phenylethylamine as a Novel Nutrient Treatment Reducing Bacterial Cell Count by Escherichia Coli O157H7 on Beef Meat
(North Dakota State University, 2013)
Since its emergence in 1980's, Escherichia coli O157:H7 has often been associated with the consumption of contaminated meat. E. coli O157:H7 continues to persist as a food borne pathogen not only in beef but many other ...
The Effects of Acetoacetic Acis on Bacterial Growth and Biofilm Formation of Cronobacter Sakazakii, Serratia Marcescens, and Yersinia Enterocolitica
(North Dakota State University, 2016)
Prevention of bacterial biofilms is an area of research currently being investigated by many research teams. The ability of a chemical to be incorporated into a material that could be used in a medical or food production ...
