Methicillin-resistant Staphylococcus aureus (MRSA) is a major public health menace. The global spread of MRSA is characterized by successive waves of epidemic clones dominating specific geographical regions. The acquisition of genes encoding resistance to heavy metals (HMRGs) is thought to be a key feature in the geographic divergence of MRSA. However, the cause-effect relationship between the presence of HMRGs and the divergence of MRSA clones remains to be clarified. In this study, we assessed the role that HMRGs may have played in the evolutionary divergence of the MRSA ST5-SCCmecI lineage in Latin America. We conducted a genomic characterization …

Pilrα Sustains Microglial Capacity To Process Myelin In A Mouse Model Of Demyelination, Kent Lin

Arts & Sciences Graduate Student Theses and Dissertations

Alzheimer's disease (AD) is characterized by amyloid-β (Aβ) plaques, neurofibrillary tangles, and neurodegeneration. Microglia, the resident immune cells of the central nervous system (CNS), play a crucial role in AD pathogenesis by containing the spreading of Aβ plaques. Genetic studies have associated a variant of the receptor Paired Immunoglobulin-like Type 2 Receptor Alpha (PILRα) with reduced risk for AD. PILRα is a receptor found on myeloid cells, such as microglia, that binds to endogenous cell surface glycoproteins and sends inhibitory signals within the cell. Additionally, it serves as an entry receptor for Herpes Simplex Virus 1. To elucidate the role …

Determining Antibiotic Efficacy On A Species Of Pseudomonas Bacteria Isolated From A Soil Sample, Austin Taylor, Peyton Wells, Alyssa Smith

Student Research Symposium

The Pseudomonas genus contains a variety of species of bacteria that play essential roles in soil health, plant growth, and microbial competition. Certain species exhibit biocontrol properties by producing antimicrobial compounds to protect plants from harmful pathogens. While our Pseudomonas species is normally non-pathogenic to plants and humans, it could transfer antimicrobial resistance genes to harmful pathogens in the environment. By studying the Minimum Inhibitory Concentration (MIC) of the isolated bacteria to several common antibiotics, we could identify antibiotic-sensitive strains that could be used in agriculture, or antimicrobial-producing strains that could serve as natural defenses for plants.
