Potential for Phenotypic Plasticity in the Hyperosmotic Stress Response of Diverse E. coli
(North Dakota State University, 2021)
Escherichia coli inhabits multiple environments that contain varying physical stresses which emphasize the importance of adaptation. The large pangenome of E. coli can account for some strain-to-strain variances in phenotype, ...
ß-phenylethylamine: A Novel Chemo-Attractant Agent
(North Dakota State University, 2021)
Bacterial metabolism and physiology are finely tuned mechanisms that maintain homeostasis for the bacterium and allow for responses to environmental signals. Responses could include anything from regulation of cell division ...
Validation of Effects of SNV From GWAS on Biofilm Phenotype Using a CRISPR System With Universal Guide RNA Sequence
(North Dakota State University, 2021)
Extraintestinal E. coli have adapted to survive in secondary environments outside of the intestines of a host. The genetically diverse phylogroup D was use to validate two previous GWAS analysis that identified single ...
The Response of Salmonella enterica and Enterohemorrhagic Escherichia coli in Low-Moisture Environments
(North Dakota State University, 2021)
The recent increase in outbreaks of low-moisture foods due to contamination with foodborne pathogens has led to an increase in interest of the response of these pathogens to low-moisture environments. In addition, knowledge ...
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 ...
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 ...
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 ...
Effects of Intensive Agricultural Management Practices on Soil Microbial Assembly and Recruitment
(North Dakota State University, 2022)
Soil microbial communities play an important role in ecosystems in various ways to promote healthy and fertile soil. However, intensive agricultural practices with excessive tillage and fertilizer applications can affect ...
Sexual Dimorphisms in the Adipose Biology of Vasoactive Intestinal Peptide Deficient Mice
(North Dakota State University, 2022)
Both VIP and PACAP deficient mice display impaired fat storage, but only the molecular adipose characteristics of PACAP KO mice are known. While mice deficient in these peptides are lean, supplementation could promote ...
