Providing Proteins To Belizean Residents Through Poultry Products, Ellis Freel

Poultry Science Undergraduate Honors Theses

Belize is a food insecure, developing country. Although Belize has plenty of nutritious food in-country, the exportation of that food to generate income contributed to a distribution issue of that nutritious food. More impoverished areas of Belize do not have access to nutritious food because of the lack of affordability and high export rates. Diets with a lack of food, or lack of balanced, nutritious food can negatively impact growth and cognitive development, especially in children. Poultry is one of the only products in Belize not able to be exported. Implementing poultry into Belizean diets would affordably alleviate food insecurity …

Fat Deposition, Β- Carotene, And Vitamin A Metabolism In Bulls, Steers, And Heifers, Tesla Trammell

Masters Theses & Specialist Projects

Bactericidal Mechanism Of Peracetic Acid Against Salmonella Mediated By Reactive Oxygen Species, Mohammed Khalid Wheib Al-Doury

Graduate Theses and Dissertations

Peracetic acid (PAA) is extensively used as a bactericidal agent in poultry processing to reduce foodborne pathogens, including Salmonella enterica serotype Typhimurium (S. Typhimurium). Despite its widespread application, the exact mechanisms underlying its bactericidal effects, particularly the role of reactive oxygen species (ROS), remain incompletely understood. This dissertation examines the role of ROS in PAA-mediated bacterial killing and explores both genetic and metabolic factors that influence bacterial susceptibility to PAA. Findings from these studies have implications for enhancing the efficacy of PAA, thereby improving food safety practices in the industry.

The first study investigates ROS as a central component …

Proteolytic Manipulation Of Neutrophil Responses And The Efferocytic Synapse By Porphyromonas Gingivalis., Kelley N. Cooper

Electronic Theses and Dissertations

Porphyromonas gingivalis (Pg) is etiologically associated with chronic periodontitis, a highly prevalent chronic inflammatory disease characterized by the destruction of hard and soft tissues of the periodontium. Pg is adapted to live in the human oral subgingival niche, a hostile environment dominated by excessive numbers of activated neutrophils and antimicrobial mediators. Its survival is contingent upon prompt and effective inactivation of neutrophil effector functions. In this dissertation, I uncover a novel pathogenic mechanism employed by Pg that disarms the antimicrobial capacity of live neutrophils and simultaneously sequesters them within macrophages. Mechanistically, RgpB, a cysteine protease produced by Pg …

Differential Responses Of Human Neutrophils To Legionella Species., Hannah E. Hanford

Electronic Theses and Dissertations

Legionella species are Gram-negative facultative intracellular bacterial pathogens commonly found in freshwater or soil environments where they survive and replicate within their natural protozoan hosts. Humans serve as an accidental host for Legionella species after inhalation of contaminated aerosolized water droplets or soil particles enabling the bacteria to enter the lungs, infect alveolar macrophages, and result in severe pneumonia. Evasion of degradation and proliferation within alveolar macrophages by Legionella species and manifestation of “Legionnaires’ disease” is dependent on the Dot/Icm type IV secretion system (T4SS). The T4SS apparatus is a needle-like channel for translocation of over ~350 effector proteins, depending …

The Atheroprotective Impact Of Anti-Mir-33a-5p/3p In Cultured Pro-Inflammatory Endothelial Cells, Kun Huang

All Dissertations

Atherosclerosis is the process of cholesterol buildup within arterial cells, which is considered a leading factor that causes certain cardiovascular diseases. Cholesterol accumulation within pro-inflammatory endothelial cells is thought to induce atherogenesis and accelerate atherosclerosis progression. Evidence suggests inhibiting the microRNA miR-33a in arterial cells may promote atheroprotection via increasing ABCA1 protein expression. MiR-33a is processed into two functional strands, miR-33a-5p and miR-33a-3p. The potential atheroprotective effect of inhibiting miR-33a-5p and/or miR-33a-3p precisely in pro-inflammatory endothelial cells is not fully understood, as data is scant regarding what potential atheroprotective impact ABCA1-dependent cholesterol within pro-inflammatory endothelial cells demonstrates, which occurs via …

Interspecific Selection In A Diverse Mycorrhizal Symbiosis, Megan A. Rúa, Jason D. Hoeksema

Biological Sciences Faculty Publications

Coevolution describes evolutionary change in which two or more interacting species reciprocally drive each other’s evolution, potentially resulting in trait diversification and ecological speciation. Much progress has been made in analysis of its dynamics and consequences, but relatively little is understood about how coevolution works in multispecies interactions, i.e., those with diverse suites of species on one or both sides of an interaction. Interactions among plant hosts and their mutualistic ectomycorrhizal fungi (ECM) may provide an ecologically unique arena to examine the nature of selection in multispecies interactions. Using native genotypes of Monterey pine (Pinus radiata), we performed a common …

Advancing Molecular Tools For The Study Of Rubus Viruses, Andrea Sierra-Mejia

Graduate Theses and Dissertations

Since blackberry yellow vein disease (BYVD) was first described, the blackberry virome has expanded significantly. BYVD is a complex disease associated with over ten viruses, yet the role of each virus in its etiology remains understudied. Studying the effect of each virus in disease development requires the identification of single infections; however, this task has been difficult for BYVD, with all field collected material over the past two decades consistently found infected by multiple viruses. Given the diversity of viruses associated with the disease and their different modes of transmission, obtaining pure virus cultures necessitate transmission of individual viruses via …

Phytoplankton Responses To Changing Irradiance And Carbon Fertilization, Alison Siersma

Graduate Theses and Dissertations (2019 - present)

Phytoplankton play a crucial role in marine ecosystems due to their innate ability to fix carbon. As atmospheric CO2 levels continue to rise from fossil fuel combustion, the resulting increase in dissolved CO2 and the concurrent decrease in ocean pH are likely to impact the phytoplankton community. The response of phytoplankton to elevated CO2 can vary significantly among species and environmental conditions (e.g. light, temperature, nutrient availability). To address these variations, an experiment was conducted using a controlled photobioreactor system, maintaining high and low light, constant temperature, nutrient levels, and two pCO2 concentrations. This study focused on two regionally relevant …
