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 ... -
Gene Regulation in Biofilms
(North Dakota State University, 2011)Sessile bacterial communities which form on the solid surface or solid-liquid interface are known as biofilms. Both single species and multispecies biofilms are characterized by an extracellular matrix of polymeric ... -
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 ... -
Glucose Uptake by the Cellulolytic Rumen Anaerobe Bacteroides Succinogenes
(North Dakota State University, 1986)Glucose uptake by the cellulclytic rumen anaerobe, Bacteroides succinogenes S85, was measured under conditions that maintained anaerobiosis and osmotic stability. This organism was found to possess a highly specific, active ... -
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 ... -
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 ... -
Hepatitis Virus B and Hepatitis Virus C Co-Infection Among HIV Patients and Development of an Enzyme Linked Immunosorbent Assay (ELISA) for Diagnosis of Equine Protozoa Myeloencephalitis
(North Dakota State University, 2012)Study 1: HIV patients with chronic HBV and/or HCV are more likely to die of liver disease and have a more rapid progression to Acquired Immunodeficiency Syndrome (AIDS) than patients solely infected with HIV. Blood samples ... -
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 ... -
Impact of Pre-Harvest Environmental Factors on the Survival of Enterohemorrhagic E. Coli and Salmonella on Lettuce
(North Dakota State University, 2015)Enteric diseases linked to fresh produce consumption are on a rise. Pathogens can contaminate produce in the pre-harvest field and can survive for long time periods. Thus, this study quantified the survival of Enterohemorrhagic ... -
In the Pursuit of Poultry: β-Phenylethylamine and Ethyl Acetoacetate as Antimicrobials on Chicken
(North Dakota State University, 2022)This research examines the effect of β-phenylethylamine (PEA), a natural trace amine commonly found in food, and ethyl acetoacetate (EAA), an FDA approved flavoring agent and food additive, as novel antimicrobials on ... -
Inhibition of Fusarium Growth and Trichothecene Accumulation in Grain by Antifungal Compounds from Lactic Acid Bacteria
(North Dakota State University, 2013)Fusarium head blight (FHB) is a widely occurring plant disease, which is caused by fungi in the genus Fusarium. FHB leads to mycotoxin accumulation on grain, which causes food safety risk and economic loss. In addition to ... -
Interactions of Aspergillus fumigatus and Pseudomonas aeruginosa Contribute to Respiratory Disease Severity and Death
(North Dakota State University, 2019)The lung was recently identified to consist of a complex microenvironment made up of microorganisms that interact with one another and the host cells via direct and indirect interactions. As a result, understanding the ... -
International Infectious Disease Management and its Role in the 'One World, One Health, One Medicine' Concept
(North Dakota State University, 2012)The knowledge that almost 75% of all new human pathogens have animal origins, requires health professionals from all fields, (i.e. human medicine, veterinary medicine, and public health professionals), to work on solving ... -
Investigation of Nutrients as Treatments of Bacterial Biofilms
(North Dakota State University, 2019)Using nutrients bacteria utilize to grow as treatments of bacterial biofilms have been investigated. This dissertation examines the problem of the prevention and treatment of biofilms by: (i) testing the effect of the ... -
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 ... -
The Link Between Gut Microbiota Metabolism and Host Gluconeogenesis by Vasoactive Intestinal Peptide
(North Dakota State University, 2022)The gut microbiota (GM) plays a beneficial role in host metabolism. In mammals, the GM ferments dietary fiber into short chain fatty acids (SCFA), like propionate, that improves glucose metabolism. Rats fed a propionate ... -
lntraspecific Variation In Pathogenic Cryptosporidium parvum
(North Dakota State University, 2010)Cryptosporidium causes cryptosporidiosis, an infectious diarrheal disease, which can become chronic and life-threatening in immunocompromised individuals. Cryptosporidium parvum and C. hominis are the primary causes of ... -
Lung Mucosal Response to Repeated Inhalational Insults with Immunomodulatory Agents in a Murine Model of Fungal Asthma: Airway Epithelium Takes the Center Stage
(North Dakota State University, 2013)Asthma is a debilitating disease of the lungs affecting 235 million people worldwide. Fungus-associated asthma leads to a particularly severe type of disease, and exposure to environmental fungi and their products is ... -
The One World / One Health Concept Applied in the Field, Laboratory, and Hospital
(North Dakota State University, 2014)New infectious disease outbreaks demand new approaches for control and prevention of disease. The world’s health organizations have adopted the One World/One Health (OWOH) concept to meet this demand. The previous approach ... -
