Evaluation Of The Efficacy Of Synthetic Glycovaccines Against Both Murine Acute Chagas Disease And Cutaneous Leishmaniasis, Colin D. Knight
Evaluation Of The Efficacy Of Synthetic Glycovaccines Against Both Murine Acute Chagas Disease And Cutaneous Leishmaniasis, Colin D. Knight
Open Access Theses & Dissertations
Chagas disease (CD) and cutaneous leishmaniasis (CL) are neglected tropical diseases caused by the protozoan trypanosomatids, Trypanosoma cruzi and Leishmania spp., respectively. There are approximately 6-8 million people infected with T. cruzi worldwide and ~300,000 people in the US. Between 700,000 and 1.2 million new cases of CL occur worldwide yearly. The approved chemotherapies for both diseases are partially effective and may cause serious adverse events, resulting in premature treatment interruption. Moreover, no effective vaccine for either disease is available. Therefore, developing a vaccine that would provide effective cross-protection against both diseases would provide a cost-effective alternative to the existing …
Sars-Cov-2: Tale Of A Microscopic Murderer, Josiah P. Garner
Sars-Cov-2: Tale Of A Microscopic Murderer, Josiah P. Garner
Quest
Independent Study
Research in progress for BIOL1406: Biology for Science Majors I
Faculty Mentor: Amina Tassa, Ph.D.
I am delighted to introduce Josiah Garner’s “SARS-CoV-2: Tale of a Microscopic Murderer.” This independent study assignment explores the impact of a novel, deadly, and worldwide virus. The assignment also examines the fast development of vaccines to control the spread and reduce the symptoms of the virus.
Josiah’s paper focuses on the early history of the emergence of COVID-19, the world response, and vaccine development. He demonstrates critical thinking skills and effectively utilizes various research methods to obtain and communicate his information. Josiah …
Mycobacterium Avium Subsp. Paratuberculosis Candidate Vaccine Strains Are Pro-Apoptotic In Raw264.7murinemacrophages, Raul G. Barletta, John P. Bannantine, Judith R. Stabel, Ezhumalai Muthukrishnan, Dirk Anderson, Enakshy Dutta, Vamsi Manthena, Mostafa Hanafy, Denise K. Zinniel

Mycobacterium avium subsp. paratuberculosis (MAP) is the etiological agent of Johne’s disease, a severe gastroenteritis of ruminants. This study developed a model cell culture system to rapidly screen MAP mutants with vaccine potential for apoptosis. Two wild-type strains, a transposon mutant, and two deletion mutant MAP strains (MOI of 10 with 1.2 × 106 CFU) were tested in murine RAW 264.7 macrophages to determine if they induce apoptosis and/or necrosis. Both deletion mutants were previously shown to be attenuated and immunogenic in primary bovine macrophages. All strains had similar growth rates, but cell morphology indicated that both deletion mutants …
Prevalence Of Sars-Cov-2 Antibodies In Liberty University Student Population, Emily Bonus
Prevalence Of Sars-Cov-2 Antibodies In Liberty University Student Population, Emily Bonus
Senior Honors Theses
In 2020, the virus SARS-CoV-2 gained attention as it spread around the world. Its antibodies are poorly understood, and little research focuses on those with few COVID-19 complications yet large numbers of close contacts: university students. This longitudinal study recorded SARS-CoV-2 antibody presence in 107 undergraduate Liberty University students twice during early 2021. After extensive data cleaning and the application of various statistical tests and ANOVAs, the data seems to show that in the case of COVID-19 infections, SARS-CoV-2 IgM antibodies are immediately produced, and then IgG antibodies follow later. However, the COVID-19 vaccine causes the production of both IgM …

West Nile virus (WNV) causes annual outbreaks globally and is the leading cause of mosquito-borne disease in Unite States. In the absence of licensed therapeutics, there is an urgent need to develop effective and safe human vaccines against WNV. One of the major safety concerns for WNV vaccine development is the risk of increasing infection by related flaviviruses in vaccinated subjects via antibody-dependent enhancement of infection (ADE). Herein, we report the development of a plant-based vaccine candidate that provides protective immunity against a lethal WNV challenge mice, while minimizes the risk of ADE for infection by Zika (ZIKV) and dengue …
Generation Of Chimeric Rhinoviruses Presenting Sars-Cov-2 Broadly Neutralizing Epitopes And Their Antigenicity Characterization, Danish Ansari
Generation Of Chimeric Rhinoviruses Presenting Sars-Cov-2 Broadly Neutralizing Epitopes And Their Antigenicity Characterization, Danish Ansari
Biotechnology Theses
The global COVID pandemic is not yet fully under control as there were over 21 million new cases of SARS-CoV-2 infections and over 50,000 deaths globally as of January of 2022. A heavily mutated variant of concern, Omicron is responsible for most of these cases which demands an urgency for a new vaccine. NIH reports over 180 vaccine candidates that use various strategies currently in development. However, a recurring concern with these vaccines is that the continuous viral mutations decrease the efficacy of vaccines. Therefore, we proposed to construct a human rhinovirus (HRV) based chimeric virus containing highly conserved, broadly …

The group B coxsackieviruses (CVBs) exist in six serotypes (CVB1 to CVB6). Disease associations have been reported for most serotypes, and multiple serotypes can cause similar diseases. For example, CVB1, CVB3, and CVB5 are generally implicated in the causation of myocarditis, whereas CVB1 and CVB4 could accelerate the development of type 1 diabetes (T1D). Yet, no vaccines against these viruses are currently available. In this review, we have analyzed the attributes of experimentally tested vaccines and discussed their merits and demerits or limitations, as well as their impact in preventing infections, most importantly myocarditis and T1D.

As it wreaked tragedy on the world, the outbreak of COVID-19 helped expose a pandemic of a different kind, one steeped in distrust and contrarianism. This movement, termed science denialism, has been lurking and undermining public health efforts for decades. Specifically, it is “the employment of rhetorical arguments to give the appearance of legitimate debate where there is none, an approach that has the ultimate goal of rejecting a proposition on which a scientific consensus exists.” Unlike skepticism, which is “doubt as to the truth of something” and works to progress both science and society, denialism is characterized by individuals’ …
The Development Of A New Pertussis Booster Formulation Via The Implementation Of New Adjuvants And Utilization Of Alternate Routes Of Administration, Megan Ashley Dejong
The Development Of A New Pertussis Booster Formulation Via The Implementation Of New Adjuvants And Utilization Of Alternate Routes Of Administration, Megan Ashley Dejong
Graduate Theses, Dissertations, and Problem Reports
Pertussis (whooping cough) is a respiratory disease caused by airborne transmission of the Gram-negative bacterium, Bordetella pertussis. Prior to the development of the first pertussis vaccines (whole cell (wP) vaccines), the incidence of pertussis was in the hundreds of thousands of cases per year, which led to the death of many children, as the infection is most severe in younger populations. Thankfully, the wP formulation resulted in a dramatic decrease in the number of annual pertussis cases, nearly eradicating the disease. However, as wP contained the whole B. pertussis bacterium (and its lipooligosaccharide (LOS)), reactogenicity issues became apparent, leading …
