Cost-Effectiveness Analysis Of Targeted Herpes Zoster Vaccination In Adults 50-59 At Increased Cardiovascular Risk, Kathleen M. Glassner

USF Tampa Graduate Theses and Dissertations

Background: Over the last twenty years the incidence of herpes zoster (HZ) infection, also known as shingles, has been increasing among adults for unknown reasons. The economic burden of HZ is currently estimated at over $1 billion per year in the United States (U.S.) and is expected to increase as the susceptible adult population ages. HZ is caused by a re-activation of the varicella zoster virus (VZV), chicken pox, and more than 95% of adults living today carry the virus with a lifetime risk of 1 in 3 for developing HZ. In 2006 the FDA approved a vaccine for the …

Evaluation Of A Microsphere-Based Immunoassay (Mia) In Measuring Diagnostic And Prognostic Markers Of Dengue Virus Infection, Jason H. Ambrose

USF Tampa Graduate Theses and Dissertations

Infections with dengue viruses (DENV) constitute both a global problem as well as locally in Florida. DENV comprise four distinct serotypes of single-stranded RNA viruses and belong to the family Flaviviridae. DENV are among the most medically important arboviruses in the world and cases may currently exceed 400 million per annum. Additionally, dengue established its first recorded endemic transmission cycle in the state of Florida in over a half century, first within the Florida Keys during 2009-10 followed by an unrelated outbreak in Martin County in 2013. The clinical profile of DENV infections ranges from a mild febrile illness …

Synthesis, In Vitro Characterization And Applications Of Novel 8-Aminoquinoline Fluorescent Probes, Adonis Mcqueen

USF Tampa Graduate Theses and Dissertations

Malaria is a parasitic disease that is caused by the plasmodium parasite. Plasmodium infection has affected man for thousands of years. With advances in drug discovery over the past century, malaria has evolved to possess resistance to most mainline therapeutics. This war of drug discovery vs plasmodium evolution continues to be fought to this very day, with attempts to eradicate malaria worldwide. Frontline treatments such as chloroquine, artemisinin, and atovaquone/proguanil have all seen parasitic resistance in strains of P. vivax as well as P. falciparum. While plasmodium possesses resistance to most classes of anti-malarials, the 8-aminoquinoline (8-AQ) class has …

Role Of Viruses Within Metaorganisms: Ciona Intestinalis As A Model System, Brittany A. Leigh

USF Tampa Graduate Theses and Dissertations

Marine animals live and thrive in a literal sea of microorganisms, yet are often able to maintain specific associations that are largely dictated by the environment, host immunity and microbial interactions. Animal-associated microbiomes include bacteria and viruses that vastly outnumber host cells, especially in the gut environment, and are considered to be integral parts of healthy, functioning animals that act as a metaorganism. However, the processes underlying the initial establishment of these microbial communities are not very well understood. This dissertation focuses on the establishment of a well-known developmental animal model, Ciona intestinalis (sea squirt), to study the establishment and …

Pollen Forecasting In Sarasota, Florida, Daniel J. Gessman

USF Tampa Graduate Theses and Dissertations

Current predictions of pollen levels rely strictly on historical Averages, regardless of environmental factors that might affect the timing of pollen release by different plants. For this thesis, the goal was to develop a statistical model that will accurately forecast pollen levels by correlating those daily counts to atmospheric and meteorological conditions. This project used ARIMA modeling on IBM’s SPSS Statistics 24 of daily pollen count information for multiple allergenic pollens in the Sarasota County, Florida area over a 11-year period. The pollen species in question for this project are oak and cypress trees, grass, and ragweed pollens; and Alternaria …

The Effect Of Antigen Polymorphisms On Serological Antibody Detection Assays Based Upon The, Kristi M. Miley

USF Tampa Graduate Theses and Dissertations

Onchocerca volvulus is a filarial parasite transmitted to humans by female Simulium spp. black flies. Infection with this parasite can cause blindness and severe skin disease among humans in Africa and the Americas. Enzyme-linked Immunosorbent Assay serological testing of OV-16 antigen is a diagnostic tool for determining effective elimination of the parasite. Programs typically rely on OV–16 ELISA to evaluate the progress towards interruption and/or elimination of disease by mass drug distribution of ivermectin and vector larvicidal control efforts. As elimination grows closer, monoclonal antibody positive controls for OV-16 ELISA become important to develop for Onchocerca testing due to the …

Disease Introduction By Aboriginal Humans In North America And The Pleistocene Extinction, Zachary D. Nickell, Matthew D. Moran

Journal of Ecological Anthropology

While overhunting and climate change have been the major hypotheses to explain the late-Pleistocene New World megafaunal extinctions, the role of introduced disease has only received brief attention. Here, we review pre-Columbian diseases endemic to aboriginal Americans and evaluate their potential to cause large-scale mortality in Pleistocene mammals. Of the probable communicable diseases present in pre-Columbian times, we regard anthrax and tuberculosis as viable candidates. These two diseases demonstrate characteristics that could have made them deadly to immunologically naïve populations. Introduced disease, as a primary cause or interacting with overhunting and climate change, could have contributed to the decline and …

Analysis Of Antibody-Induced Plasmodium Falciparum Sporozoites Through Scanning Electron Microscopy, Sagorika Bera

USF Tampa Graduate Theses and Dissertations

Malaria is a devastating disease that continues to affect millions of people worldwide every year. Specifically, Plasmodium falciparum is the most common human malaria parasite, particularly in sub-Saharan Africa. P. falciparum causes the most malignant and debilitating symptoms with the highest mortality and complication rates. Even with the worldwide efforts of many researchers and organizations, the road to discovering a vaccine has been difficult and challenging. Due do to the improvements in in vitro liver stage assays as well as rodent models of mammalian malaria, pre-erythrocytic stages of malaria have become a more accessible target for experimental studies. These vaccine …

Development Of Tools For Stable Transfection In The Human Filarial Parasite Brugia Malayi Via The Piggybac Transposon System, Johan Chabanon

USF Tampa Graduate Theses and Dissertations

Brugia malayi is one of three species of nematode known to cause lymphatic filariasis (LF) in humans. LF infects over 120 million people, causing debilitating disease. Various global programs have been launched in the past 20 years to eliminate LF. These programs have greatly scaled up the resources and efforts allocated to halting the transmission and reducing disease burden. Only a few drugs are used to treat LF, and resistance is thus a devastating possibility. Research aimed at identifying new drug targets could therefore prove essential in elimination of LF.

Genetic manipulation of B. malayi has been limited to transient …
