An Impedimetric Aptasensing System For The Rapid Detection Of Salmonella Typhimurium, America Sotero

Graduate Theses and Dissertations

Salmonella Typhimurium is a foodborne pathogen associated with raw and undercooked eggs, poultry, beef, fruits, and vegetables. In the United States, Salmonella is responsible for approximately 1.2 million illnesses, 23,000 hospitalizations, and 450 deaths annually. For many years, conventional detection methods such as culture-dependent and PCR-based methods have been the “golden standards” for the detection of this pathogen due to their high sensitivity and reliability. However, they still have some disadvantages such as long enrichment steps and high costs that need to be overcome. The development of a rapid and reliable method for the detection of S. Typhimurium is needed …

The Investigation Of Surface Structures On Various Pathogens And Their Interactions With The Human Immune System, Carmen M. Villalobos

Biomedical Engineering ETDs

The cell surface is the first interface the host immune system encounters and

its investigation has led to a better understanding of cellular biology and types of

pathways that pathogens target in a host cell. The cell surface has evolved to include

many functions such as manipulation of the cytoskeleton, cell signaling, membrane

trafficking, adhesion, and integration into host tissue. The pathogens of interest are

the pathogenic fungus, Candida albicans, and the parasite, Giardia lamblia and we

investigate the consequences of drug treatments on the cell surface, leading to

promising new targets.
