Bacterial Load In Virtual Reality Headsets, Benjamin Creel
Bacterial Load In Virtual Reality Headsets, Benjamin Creel
Honors Theses
Virtual reality technology is a rapidly growing field of computer science. Virtual reality utilizes headsets which cover the user’s eyes, nose, and forehead. In this study, I analyzed the potential for these headsets to become contaminated with bacteria. The nosepieces and foreheads of two HTC Vive VR headsets of the Department of Computer Science of the University of Mississippi were sampled over the course of a seven-week Immersive Media (CSCI 447) course. Serial dilutions were performed, and samples were plated on various culture media. Following incubation, counts of bacteria were determined. DNA was extracted from bacterial growth on plates from …
The Msaabcr Operon Mutant Staphylococcus Aureus Is Deficient In Persister Cells, Aaliyah D. Cole
The Msaabcr Operon Mutant Staphylococcus Aureus Is Deficient In Persister Cells, Aaliyah D. Cole
Honors Theses
Persister cells comprise a phenotypic variant that shows extreme antibiotic tolerance resulting in chronic infections. While this phenomenon has posed a great threat in public health, mechanism underlying their formation in Staphylococcus aureus remains largely unknown. Increasing evidence of the presence of persister cells in recalcitrant infections underscores the great urgency to unravel the mechanism by which these cells are developed. The Elasri Research group characterized msaABCR operon that plays roles in regulation of virulence, biofilm development and antibiotic resistance. It was hypothesized that the operon also plays a role in persister cell formation. In this study, the persister cell …
The Effect Of Increased Exposure Of Uvc Light On Human Skin Microbiota, T'Kylia S. Moss
The Effect Of Increased Exposure Of Uvc Light On Human Skin Microbiota, T'Kylia S. Moss
Honors Theses
Many methods have been employed to prevent infections from opportunistic pathogens in immunocompromised individuals. Among these are the use of ultraviolet light (UV). In this study, UVC light, was found to have a deleterious effect on specific skin flora. Organisms tested included Acinetobacter baumanii, Candida albicans, Candida kefyr, Corynebacterium renale, Enterococcus faecalis, Pseudomonas aeruginosa, Staphylococcus aureus, Staphylococcus epidermidis, and Streptococcus pyogenes. Nutrient agar was used to cultivate most organisms. Blood agar was used for the cultivation of Streptococcus pyogenes and Enterococcus faecalis. Bacterial suspensions were made and utilized to plate each organism onto a set of 7 nutrient agar or …
Discovering New Antibiotics: Bacterial Extracts Separated By Thin-Layer Chromatography Inhibit The Growth Of Staphylococcus, Heidi Hughes
Discovering New Antibiotics: Bacterial Extracts Separated By Thin-Layer Chromatography Inhibit The Growth Of Staphylococcus, Heidi Hughes
Honors Theses
Many bacteria have become resistant to commonly used antibiotics because of antibiotic use in people and animals. Therefore, new antibiotics are needed that will inhibit these resistant bacteria. Bacteria found in soil are a likely source for new antibiotics because of the limited available nutrients found in the soil. We isolated soil bacteria and screened them for antibiotic production against Staphylococcus epidermidids. Methanol extracts were made from entire agar plates of the soil bacteria that inhibited S. epidermidis. These extracts were spotted on a lawn of Staphylococcus aureus; growth inhibition was measured to comfirm that the extracts contained the …
