Geographic And Socioeconomic Risk Factors For Sporadic Cryptosdporidiosis And E. Coli Infection In East Tennessee, Ingrid Elizabeth Luffman
Doctoral Dissertations
This research examines risk factors for sporadic cryptosporidiosis and Escherichia coli (E. coli) O157 infection in East Tennessee, using case-control and retrospective ecological approaches. Multiple models and approaches are used to identify risk factors for the two diseases, and to examine the effect of scale on risk for disease in the individual and in the population. Risk factors examined are animal density, land use, geology, surface water impairment, poverty rate and availability of private water supply. The research objectives are, first, to identify risk factors for E. coli O157 and cryptosporidiosis in East Tennessee by relating disease data …

Modulating T Cell Responses To Control Stromal Keratitis, Tamara Antia Veiga Parga
Doctoral Dissertations
Herpetic stromal keratitis (SK) is an immunoinflammatory corneal lesion caused by herpes simplex virus (HSV) infection. This infection, in some cases, can result in a chronic immunoinflammatory lesion that is the most common cause of infectious blindness in the developed world. Studies in animal models have revealed that SK lesions are orchestrated mainly by IFN-gamma producing CD4+ T cells (Th1) and neutrophils that infiltrate the corneal stroma.
The first part of this dissertation (I) reviews literature on HSV induced corneal SK immunopathology and the role of Tregs in viral infections. It also focuses on the understanding of HSV-1 induced immunoinflammatory …
