Tetr Family Regulator Farr Variation Controls Antimicrobial Fatty Acid Efflux In Staphylococcus Aureus, Camryn M. Bonn
Tetr Family Regulator Farr Variation Controls Antimicrobial Fatty Acid Efflux In Staphylococcus Aureus, Camryn M. Bonn
Electronic Thesis and Dissertation Repository
To colonize human skin and survive within abscesses, Staphylococcus aureus has evolved mechanisms to evade host innate defenses. USA300 has become the predominate community-acquired methicillin-resistant S. aureus (CA-MRSA) clone, which can be in part attributed to detoxification of unsaturated free fatty acids (uFFA) found in sebum and the nares. Our lab has previously identified the TetR family regulator FarR responsible for induction of the resistance-nodulation-division (RND) superfamily efflux pump FarE to promote efflux of toxic uFFA. However, RND family efflux pumps remain poorly characterized in Gram-positive species and the mechanism by which FarR regulates FarE has yet to be determined. …

Hybridized Polymeric Nano-Assemblies: Key Insights Into Addressing Mdr Infections, Ryan Landis
Doctoral Dissertations
Multidrug-resistant (MDR) bacteria contribute to more than 700,000 annual deaths world-wide. Millions more suffer from limb amputations or face high healthcare treatment costs where prolonged and costly therapeutic regimens are used to counter MDR infections. While there is an international push to develop novel and more powerful antimicrobials to address the impending threat, one particularly interesting approach that has re-emerged are essential oils, phytochemical extracts derived from plant sources. While their antimicrobial activity demonstrates a promising avenue, their stability in aqueous media, limits their practical use in or on mammals. Inspired by the versatility of polymer nanotechnology and the sustainability …

Necrotizing Fasciitis, Holly Herron
Nursing Student Class Projects (Formerly MSN)
Necrotizing fasciitis also known as necrotizing soft tissue infections (NSTIs) is a rare life-threatening infection that involves the skin and soft tissue. A rapid and accurate diagnosis of NSTIs must be identified by healthcare providers to diminish morbidity and mortality. NSTIs are characterized by progressive necrosis of subcutaneous tissue and fascia involving large areas of tissue (Lin, Chang, Lai, Lin, & Chen, 2013). Hippocrates (500 BC) described necrotizing fasciitis as “diffuse erysipelas caused by trivial accidents [where] flesh, sinews, and bones fell away in large quantities, [leading to] death in many cases” (Lancerotto, Tocco, Salmaso, Vindigni & Bassetto, 2012).
