Antibiotic Drug Discovery Targeting Bacterial Metabolism, Miranda J. Wallace
Antibiotic Drug Discovery Targeting Bacterial Metabolism, Miranda J. Wallace
Theses and Dissertations (ETD)
Over the last century, the use of antibiotics has enabled many advances in modern medicine, making life as we know it possible. In recent years, however, emerging bacterial resistance to virtually all major antibiotic classes has resulted in a worldwide increase in morbidity, mortality, and financial burden associated with drug resistant infections. The antimicrobial resistance crisis presents an urgent need for new antimicrobials with distinct mechanisms of action from existing drugs. The current pharmaceutical pipeline of new antibiotics is limited due to three obstacles: a lack of understanding of resistance mechanisms, a dearth of novel mechanisms of action among new …
Glycolic Acid Utilization In Two Species Of Marine Bacteria, Erik S. Timsak
Glycolic Acid Utilization In Two Species Of Marine Bacteria, Erik S. Timsak
STAR Program Research Presentations
Interactions between bacteria and phytoplankton are crucial for the cycling of organic matter in marine environments. Around 50% of organic carbon taken up by marine bacteria is converted into inorganic carbon. The uptake of organic carbon by marine bacteria exuded from phytoplankton is a key factor in regulating the marine carbon cycle. One such molecule that is exuded by phytoplankton and then uptaken by marine bacteria is called glycolate - the anion of glycolic acid, a two caron molecule. Glycolate is exuded by phytoplankton during photorespiration and 10-50% of dissolved organic carbon in marine environments is comprised of glycolate. Additionally, …
Investigating The Proteinaceous Regulome Of The Acinetobacter Baumannii, Leila G. Casella
Investigating The Proteinaceous Regulome Of The Acinetobacter Baumannii, Leila G. Casella
USF Tampa Graduate Theses and Dissertations
Acinetobacter baumannii is an opportunistic pathogen that overtime has evolved into one of the most problematic pathogens due to its ability to overcome antibiotic pressures and harshly environments in the host and hospital environments. In this context, its genomic evolution due to its capacity to acquire genes that contribute to its pathogenic and antibiotic resistance nature has been the subject of research in the last decades providing with the identification of several proteins aiding in the process of pathogenicity. Although these findings have contributed to our understanding of A. baumannii pathogenic traits, the regulatory network that control their expression are …
