Discovery Of New Antimicrobial Options And Evaluation Of Aminoglycoside Resistance Enzyme-Associated Resistance Epidemic, Selina Y. L. Holbrook
Discovery Of New Antimicrobial Options And Evaluation Of Aminoglycoside Resistance Enzyme-Associated Resistance Epidemic, Selina Y. L. Holbrook
Theses and Dissertations--Pharmacy
The extensive and sometimes incorrect and noncompliant use of various types of antimicrobial agents has accelerated the development of antimicrobial resistance (AMR). In fact, AMR has become one of the greatest global threat to human health in this era. The broad-spectrum antibiotics aminoglycosides (AGs) display excellent potency against most Gram-negative bacteria, mycobacteria, and some Gram-positive bacteria, such as Staphylococcus aureus. The AG antibiotics amikacin, gentamicin, kanamycin, and tobramycin are still commonly prescribed in the U.S.A. for the treatment of serious infections. Unfortunately, bacteria evolve to acquire resistance to AGs via four different mechanisms: i) changing in membrane permeability to …
The Role Of Pro-Inflammatory Mediators Ifnβ And Prostaglandin E2 In Suppression Of Innate Immunity To Listeria Monocytogenes, Michelle G. Pitts
The Role Of Pro-Inflammatory Mediators Ifnβ And Prostaglandin E2 In Suppression Of Innate Immunity To Listeria Monocytogenes, Michelle G. Pitts
Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics
As a foodborne pathogen, Listeria monocytogenes (Lm) encounters many barriers to invasion and dissemination in the host that may change the nature of host response. Lm has been most commonly studied using intravenous (i.v.) inoculation, however, a method that delivers a bolus of bacteria directly to the bloodstream. Thus, little is known about what systemic and local mediators are triggered during the natural course of infection and how these may impact susceptibility. Our laboratory used foodborne transmission of Lm in mice to assess whether the method of transmission and the specific organ microenvironment could affect infection-induced secretion of …
Synthesis And Biological Evaluation Of Novel Drug Candidates To Address Drug Resistance In Tuberculosis And Fungal Diseases, Huy Ngo
Theses and Dissertations--Pharmacy
Tuberculosis (TB) and fungal infections are two of the most lethal infectious diseases worldwide due to the emergence of drug-resistant Mycobacterium tuberculosis (Mtb) and fungal strains that can resist the most potent antimicrobial drugs currently employed. Due to the rise of these drug resistant strains, effective treatment options for these two infections are limited. This dissertation aims at exploring novel drug scaffolds to help combat drug resistance in TB and fungal infections.
TB caused by the pathogenic Mtb is, alongside with human immunodeficiency virus acquired immunodeficiency virus (HIV), the deadliest infectious disease worldwide with approximately 2-3 billion people …
