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 ...
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 ...
Characterizing Humidity, Sex, and B-Cell Gene Regulation in Fungal Allergic Asthma
(North Dakota State University, 2020)
Asthma is a debilitating lung disease that affects nearly 300 million people worldwide. Environments with high humidity and subsequent mold exposure often trigger allergic asthma. Sex differences have been reported in the ...
Assessment of Vacuum Steam Pasteurization to Improve Safety and Quality of Low Moisture Foods
(North Dakota State University, 2016)
Low moisture foods such as grains, seeds, spices and flour are part of our daily diet. While they are rich in bioactive compounds, they can be minimally processed or often consumed raw. Several outbreaks due to Salmonella ...
A Porcine Circovirus Vaccine with Enhanced Capabilities
(North Dakota State University, 2016)
Porcine circovirus type 2 (PCV2) is a pathogen of swine. Vaccines against PCV2 are available, although none are capable of differentiating infected from vaccinated animals (DIVA). Positive and negative DIVA markers were ...
Characterization of a Novel Cryptosporidium Genotype in Red-Winged Black Birds
(North Dakota State University, 2014)
Cryptosporidium species cause cryptosporidiosis, characterized by acute gastroenteritis in humans and animals worldwide. Knowledge of the diversity of Cryptosporidium among mammals and birds is incomplete, especially in ...
