16S Ribosomal RNA and Phylograms: Characterizing Student Reasoning to Learning Outcomes from the American Society for Microbiology Curriculum
(North Dakota State University, 2017)
The American Society for Microbiology (ASM) has established a suggested curriculum for introductory microbiology courses that includes a focus on evolution. However, no data is published to describe how proficiently students ...
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 ...
Phenotypic and Genotypic Effects of FlhC Mediated Gene Regulation in Escherichia Coli O157:H7
(North Dakota State University, 2011)
Escherichia coli (E.coli) 0157:H7, a pathogen belonging to the enterohemorrhagic group of E.coli, has long been a concern to human health. The pathogen causes a myriad of symptoms in humans, ranging from diarrhea and malaise ...
Attachment and Biofilm Formation of Foodborne Pathogens
(North Dakota State University, 2017)
Outbreaks of Listeria monocytogenes, Salmonella, and Escherichia coli are increasingly attributed to fresh produce. Current control measures have been assessed for decades, with no alternatives adopted. Sources were ...
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 ...
Physical and Chemical Treatments for Bacterial Biofilms
(North Dakota State University, 2014)
Physical and chemical treatments have been investigated for the treatment to remove biofilms. This thesis examines the problem of the removal and prevention of biofilms by: (i) using a water jet to determine biofilm stability ...
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 ...
