Production Of A Candidate Recombinant Protein Vaccine For Mannheimia Haemolytica In Lettuce And Tobacco Chloroplasts, Coby K. Martin Jul 2018

Production Of A Candidate Recombinant Protein Vaccine For Mannheimia Haemolytica In Lettuce And Tobacco Chloroplasts, Coby K. Martin

Electronic Thesis and Dissertation Repository

The cattle industry worldwide is ravaged by bovine respiratory disease (BRD), a bacterial disease caused by Mannheimia haemolytica. Recent efforts to design vaccines against M. haemolytica focus on a virulence factor, leukotoxin, in addition to surface lipoproteins. Plant-based protein production is a safe and inexpensive alternative to traditional methods. Edible vaccines deliver antigens to pharyngeal tissues, which can provide local immunization against M. haemolytica prior to its progression into the lungs. In this project, a chimeric protein containing M. haemolytica antigens was produced in tobacco chloroplasts as a candidate edible vaccine for BRD. Attempts were made to transform lettuce …


Development Of A Rapid Diagnostic Assay For The Colorimetric Detection Of Bacterial And Viral Pathogens Using Loop-Mediated Isothermal Amplification Coupled With A Peptide Nucleic Acid And Gold Nanoparticle Reporter System, William Brown Jul 2018

Development Of A Rapid Diagnostic Assay For The Colorimetric Detection Of Bacterial And Viral Pathogens Using Loop-Mediated Isothermal Amplification Coupled With A Peptide Nucleic Acid And Gold Nanoparticle Reporter System, William Brown

All NMU Master's Theses

Detection of pathogenic agents remains pivotal to the control and prevention of infectious disease. While diagnostic methods continue to break barriers, the need for accurate, sensitive, and rapid methods persists. Current methods for pathogen detection, including culture, immunochemical, or molecular-based techniques, are subject to significant limitations that restrict their clinical utility. Point-of-care (POC) tests have received attention for the diagnostic screening of infectious disease, with benefits of simplicity, affordability, and convenience. This study describes the development of a novel loop-mediated isothermal amplification (LAMP) reaction followed by a peptide nucleic acid (PNA) probe and gold nanoparticle (AuNP) detection system that results …


Optimizing Genetic Manipulation Of Methanogens Through Faster Cloning Techniques, Merrisa Jennings May 2018

Optimizing Genetic Manipulation Of Methanogens Through Faster Cloning Techniques, Merrisa Jennings

Biological and Agricultural Engineering Undergraduate Honors Theses

Methanogenesis is the biological production of methane. Only anaerobic archaea known as methanogens are capable of such a metabolic feat. They have strict living conditions and substrate sources which determine their rate of metabolism. This is of particular importance from a greenhouse gas reduction perspective or biogas capturing perspective. One of the best ways to optimize methanogen methane production is via genetic manipulation. The current procedures are timely though, therefore a faster cloning processes should be developed. The objective of this study was to optimize a premade genetic transformation kit known as the Gibson Kit. The Gibson Kit was supposed …
