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 ... -
Rationally Reconstructed and Attenuated Vaccines for Epidemic Response
(North Dakota State University, 2021)Most of the recent viral outbreaks were caused by highly mutating RNA and single stranded DNA viruses. The availability of safe and effective rapid response vaccines early on in an epidemic situation, along with good vaccine ... -
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 ... -
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 ... -
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 ... -
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 B-Cell Role in Autoimmunity
(North Dakota State University, 2023)This review is focused on B-cell’s role in autoimmunity and was conducted by reading current papers across a variety of journals and compiling the information learned in this process. Specifically, this review paper ... -
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 ... -
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 ... -
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 ... -
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, ... -
The Effects of Agricultural Factors on Foodborne Bacterial Pathogen Isolation, Attachment, and Survival
(North Dakota State University, 2020)The pathogens enterohemorrhagic Escherichia coli (EHEC), Salmonella enterica, and Listeria monocytogenes are prominent causes of foodborne illness. If they reach the pre- or post-harvest environment of produce, they can ... -
Transmission and Pathogenesis of Swine Torque-Teno Virus 1 (TTSuV1)
(North Dakota State University, 2019)Torque-teno viruses (TTVs) are small ubiquitous non-enveloped single-stranded circular DNA viruses. Since their discovery in a post-transfusion hepatitis patient, they have been isolated in several vertebrate hosts with ... -
The Decomposition Ecology and Microbial Forensics of the Postmortem Microbiome
(North Dakota State University, 2021)Every living organism dies and is decomposed into nutrients and by-products. This is lead initially by the normal flora of the newly deceased host. The postmortem microbiome, so-called “necrobiome”, undergoes temporal ... -
Current Status of the Biology, Pathogenesis, and Impacts of Ebola Virus
(North Dakota State University, 2021)Ebola viruses (EV) are single-stranded negative-sense RNA viruses belonging to the Filoviridae family. There are 6 species of Ebola, and four of them can cause Ebola virus disease (EVD) in humans. Ebola viral hemorrhagic ... -
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 ... -
An Overview of SARS-CoV-2 Covid-19: Epidemiology, Origin, and Pathology
(North Dakota State University, 2020)Following SARS (years 2002-2003) and MERS (year 2012) outbreaks, humans have faced a new highly contagious virus, SARS-COV-2, which began late 2019 and resulted in a pandemic (COVID-19 pandemic). The disease has been spread ... -
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) ... -
