Comparative Investigation Of Bacterial Adhesion On Medical Device Thermoplastics, Dev V. Mehta
Comparative Investigation Of Bacterial Adhesion On Medical Device Thermoplastics, Dev V. Mehta
Honors Theses
This project will focus on determining if differences in bacterial cell wall composition influences adhesiveness to thermoplastic materials used to construct patient orthotic splints. Bacteria with decreased adhesion are unable to remain bonded to orthotic splints, increasing its ability to transfer to a patient’s wound, leading to an infection. Antibiotic resistant bacteria used in this investigation included gram-positive cocci vancomycin-resistant (VRE) Enterococcus faecalis, methicillin-resistant Staphylococcus aureus (MRSA), and gram-negative rods extended-spectrum beta-lactamase (ESBL) Escherichia coli and Pseudomonas aeruginosa. Each test bacterium is a major pathogen causing healthcare-associated infections (HAIs). Saline, artificial perspiration, and ascites fluids were used to determine the …
Pseudomonas Aeruginosa Exoenzyme Y Enzymatic Activity Inhibits Exoenzyme S-Induced Caspase Activation But Not Cytotoxicity In Pulmonary Microvascular Endothelial Cells, Connor Holm
Honors Theses
Pseudomonas aeruginosa (P. aeruginosa) is the most common cause of ventilator-associated pneumonia in intensive care unit patients. P. aeruginosa utilizes a type III secretion system that injects exoenzymes U, S, T, and/or Y into the host cell cytosol. A majority of clinically isolated P. aeruginosa strains express ExoY often in combination with ExoU and ExoT, or ExoS and ExoT. Host signaling mechanisms in response to intoxication with individual exoenzymes have been extensively studied, yet little is known about host cell response to co-intoxication. In this study, pulmonary microvascular endothelial cells (PMVECs) were infected with P. aeruginosa strains expressing different combinations …
Redesigning Nasogastric Feeding Tubes To Prevent Dislodgement, Sydney Ruth Rester, Shelby Lynn Berry
Redesigning Nasogastric Feeding Tubes To Prevent Dislodgement, Sydney Ruth Rester, Shelby Lynn Berry
Honors Theses
Seniors at the University of Mississippi studying biomedical engineering complete a senior project that seeks to solve a problem in healthcare. Our team, composed of Sydney Rester, Shelby Berry, Andrew Ulmer, and Alex Bromley, sought to improve care associated with nasogastric feeding tubes. We identified two major problems: clogging and tube dislodgement. To address the problem of dislodgement, the team crafted a new feeding tube design with a balloon attachment. The attachment prevents a patient from pulling the feeding tube out and keeps the tube from dislodging due to normal patient movement. We further determined that our tube should be …

Analyzing The Survival Rate Of Clinically Pathogenic Bacteria On Occupational Therapy Devices Used During Full Hip Replacement Rehabilitation, Meredith Rippy
Analyzing The Survival Rate Of Clinically Pathogenic Bacteria On Occupational Therapy Devices Used During Full Hip Replacement Rehabilitation, Meredith Rippy
Honors Theses
An increasing concern of the healthcare system has been that of Healthcare-Associated Infections (HAIs). HAIs currently account for approximately 1.7 million infections and 99,000 deaths per year in United States hospitals. HAI’s (formerly called nosocomial infections) are defined as infections that develop in patients who have been in residence in a healthcare facility (i.e., in-patient clinics) for 48 hours or longer and who previously had no evidence of infection prior to admission. Consequences of HAIs include increased length of hospital stay, exposure to high frequency antibiotics, sepsis, and in unfortunate cases, death. In out-patient environments where patients are receiving rehabilitative …
