Development And Validation Of An Isothermal Amplification Assay For Eastern Equine Encephalitis Virus, Mikayla D. Maddison
Development And Validation Of An Isothermal Amplification Assay For Eastern Equine Encephalitis Virus, Mikayla D. Maddison
USF Tampa Graduate Theses and Dissertations
Eastern Equine Encephalitis virus (EEEV) is a neurotrophic alphavirus for which there is no effective treatment or vaccine for humans. Periodic outbreaks in the Eastern United States represent an ongoing public health problem; Florida serves as the reservoir for EEEV for the rest of the country. Reverse transcription-polymerase chain reaction (RT-PCR) is the current gold standard for molecular diagnostic testing of the presence of EEEV in vectors. However, RT-PCR is technically complex and can be difficult for mosquito control districts to utilize. In order to provide a simple, cost-effective alternative for mosquito surveillance and control, a novel one step reverse …
Evaluation Of A Microsphere-Based Immunoassay (Mia) In Measuring Diagnostic And Prognostic Markers Of Dengue Virus Infection, Jason H. Ambrose
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 …

Respiratory Syncytial Virus-Infected Mesenchymal Stem Cells Regulate Immunity Via Interferon-Beta And Indoleamine-2,3-Dioxygenase, Michael B. Cheung

Respiratory syncytial virus (RSV) is the most common cause of acute lower respiratory tract infection in young children worldwide, accounting for an estimated 33.8 million cases of respiratory disease, over 3 million of which require hospitalization, and between 66,000 and 199,000 deaths in this susceptible population. Additionally, severe RSV infection early in life is associated with an increased risk of wheeze and other airway disorders later in life. Despite this, there is currently no vaccine or economically reasonable prophylactic regimen to prevent infection. While disease is typically more severe in infancy RSV can infect throughout the lifespan repeatedly as the …
Prenatal Stress, Depression, And Herpes Viral Titers, Pao-Chu Hsu
Prenatal Stress, Depression, And Herpes Viral Titers, Pao-Chu Hsu
USF Tampa Graduate Theses and Dissertations
Recent studies suggest that some cases of prenatal depression may be associated with reactivation of latent infections of the herpesvirus family. The possible relationships among stress, prenatal depression, and herpes viral reactivation in pregnancy are understudied and the molecular pathways such as the neuroimmune biogenic amine pathway are unidentified. Chronic stress shifts the T helper-1 cell (Th1) cytokine profile to a Th2 profile, which favors virus induced pathogenesis and survival. Pregnancy is also associated with a similar Th2 dominance. In non-pregnant individuals, exposure to psychological or physical stress may be associated with latent herpes viral reactivation and could result in …
Innate Immune Responses To Respiratory Syncytial Virus: Age-Associated Changes, Terianne Maiko Wong
Innate Immune Responses To Respiratory Syncytial Virus: Age-Associated Changes, Terianne Maiko Wong
USF Tampa Graduate Theses and Dissertations
Respiratory syncytial virus (RSV) infection causes ~64 million cases of respiratory disease and 200,000 deaths annually worldwide, yet there is no broadly effective prophylactic or treatment regimen. RSV can produce acute respiratory illness in patients of all ages but strikes the age extremes, infants and the elderly, with highest frequency presumably due to innate immune deficiencies. A higher morbidity and mortality has been reported for the elderly above 65 years of age, which has been attributed to immune senescence. Efforts to generate an effective vaccine have thus far been unsuccessful.
The innate immune system provides the first line of defense …
Therapeutic Peptide-Based Vaccination Strategies Against Hpv-Induced Cancers, Kelly Barrios Marrugo
Therapeutic Peptide-Based Vaccination Strategies Against Hpv-Induced Cancers, Kelly Barrios Marrugo
USF Tampa Graduate Theses and Dissertations
There is an urgent need for the development of an effective therapeutic vaccine against cancer caused by human papilloma virus (HPV). We focused on HPV-induced malignancies because of their high worldwide prevalence (e.g., cervical carcinoma and head & neck cancer). A successful therapeutic vaccine could prevent the 250 000 deaths/year worldwide and the 2.25 billion dollars that
are expended in related care in the US.
We used an HPV-induced mouse cancer model to test vaccines
composed of a CD8 T cell peptide epitope administered with potent adjuvants designed to generate vast numbers of high avidity cytotoxic T lymphocytes specific for …
