Studies in Pathogenesis of a Novel Isolate of Cronobacter Sakazakii using an In Vitro Blood Brain Barrier Model
(North Dakota State University, 2013)
Genus Cronobacter is a member of the family Enterobacteriaceae consisting of several opportunistic species. The primary focus of this study was to utilize an in vitro co-culture model of the blood brain barrier to investigate ...
Cronobacter Sakazakii Characterization and Analysis of Cytotoxicity in Microvascular Endothelial Cells
(North Dakota State University, 2014)
Contamination of powdered infant formulas by the bacteria Cronobacter sakazakii can pose serious risk to infants and neonates who consume the formula and subsequently develop C. sakazakii related illnesses such as sepsis ...
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 ...
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 ...
Efficacy of Chlorine Dioxide Fumigation on the Spores of Paenibacillus larvae, the Causative Agent of American Foulbrood Disease in Honeybees
(North Dakota State University, 2019)
Honeybees (Apis mellifera) play a critical role in agricultural pollination. However, their health and numbers are in decline. A major cause of this decline is bacterial diseases, of which American foulbrood disease (AFB) ...
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. ...
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 ...
