Pathogenicity Of Acinetobacter Calcoaceticus, Kaitlan A. Sullivan
Pathogenicity Of Acinetobacter Calcoaceticus, Kaitlan A. Sullivan
MUSC Theses and Dissertations
Acinetobacter is a genus of gram-negative bacteria that have been appearing frequently in hospitals contributing to infections in the blood, lungs, urinary tract, and other parts of the body. It infects patients with weakened immune systems that are placed on ventilators, after the use of catheters, or have any other open wounds produced by prolonged hospital stays. This genus of bacteria is problematic due to its high probability of becoming resistant to multiple classes of antibiotics. Thus, we are determining the pathogenicity of clinical isolates of Acinetobacter calcoaceticus using the organism Caenorhabditis elegans as a model.
We are testing …
The Use Of Aloe-Based Silver Nanoparticles As A Possible Treatment For Contaminated Water, Lozetta Davis
The Use Of Aloe-Based Silver Nanoparticles As A Possible Treatment For Contaminated Water, Lozetta Davis
Scholar Week 2016 - present
Water contamination is a world-wide issue that causes the death of millions yearly. This comes from regularly tainted water with water borne pathogens, which is typically seen in undeveloped areas. As antibiotics are used more, more resistance is being seen, and thus newer methods of microbial contamination need to be developed. Silver nanoparticles have shown success in microbial contamination on petri dishes, but not in a water system. It was hypothesized that if silver nanoparticles were added to bacteria contaminated water they would be able to reduce the amount of bacteria present. Silver nanoparticles that are synthesized from plants such …
Study Of Microbial Load In Water Samples From Hydraulic Fracturing Adjacent Streams, Anthony W. Ruocco
Study Of Microbial Load In Water Samples From Hydraulic Fracturing Adjacent Streams, Anthony W. Ruocco
Senior Projects Spring 2023
Hydraulic Fracturing, also known as “fracking,” is an oil and gas extraction method in which a mix of water, sand, and chemicals are shot at high pressures into subterranean areas. This process has the potential to not only damage landscapes and impact wildlife, but also to pollute groundwater and surface water, as well as streams. Water collected near fracking sites may show the effects of hydraulic fracturing on microbial communities, and examination of bacterial growth can possibly give indication of habitat degradation or the effect of inorganic compounds introduced by the hydraulic fracturing process. Samples collected by a Jude Lab …
Characterization Of The Clostridioides Difficile Glycosyl Hydrolase Ccsz, Brian Lowrance
Characterization Of The Clostridioides Difficile Glycosyl Hydrolase Ccsz, Brian Lowrance
Theses and Dissertations (Comprehensive)
Bacteria inhabit many of the harshest environments on Earth; persisting and thriving in conditions thought to be unsuitable for life. One common strategy to withstand these environments is the formation of a biofilm. Biofilm composition varies greatly, depending on the underlying community that produces it. Cellulose, a polymer consistently prevalent in biofilms, has been identified as a virulence factor in many pathogens and is suspected to be involved in pathogenesis by Clostridioides difficile. C. difficile is the #1 cause of hospital acquired diarrhea, which can range from mild to life-threatening infections. Biofilm formation is hypothesized to be involved in …
A Metagenomic Analysis Of The Microbial Communities Associated With Different Hydrothermal Vent Chimneys, Laura Murray
A Metagenomic Analysis Of The Microbial Communities Associated With Different Hydrothermal Vent Chimneys, Laura Murray
WWU Graduate School Collection
Hydrothermal vents host a diverse community of microorganisms that utilize chemical gradients from the venting fluid for their metabolisms. The venting fluid can solidify to form chimney structures that these microbes adhere to and colonize. These chimney structures are found throughout many different locations in the world’s oceans. In this study, comparative metagenomic analyses of microbial communities on five chimney structures from around the Pacific Ocean were elucidated focusing on the core taxa and genes that are characteristic for each of these hydrothermal vent chimneys, as well as highlighting differences among the taxa and genes found at each chimney due …
