Evolution Of Bordetella Pertussis Genome May Play A Role In The Increased Rate Of Whooping Cough Cases In The United States, Kevin Loftus May 2018

Evolution Of Bordetella Pertussis Genome May Play A Role In The Increased Rate Of Whooping Cough Cases In The United States, Kevin Loftus

Senior Honors Projects, 2010-2019

Bordetella pertussis is the bacterium responsible for pertussis, a disease commonly referred to as whooping cough. Recently, pertussis has made a resurgence in the U.S. despite high-vaccination coverage. Possible causes of the increased number of pertussis cases include genetic evolution of B. pertussis, increased awareness of the disease, better laboratory diagnostics, and the switch from a whole-cellular (wP) vaccine to an acellular vaccine (aP) in the 1990s. Fortunately, just as B. pertussis is evolving, so is the arsenal of technologies used to understand and combat this pathogenic bacterium. Whole genome sequencing is one technology that helps researchers better understand …

Cost-Effectiveness Analysis Of Targeted Herpes Zoster Vaccination In Adults 50-59 At Increased Cardiovascular Risk, Kathleen M. Glassner Nov 2017

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 …


Peptide Vaccine Formulation Controls The Duration Of Antigen Presentation And Magnitude Of Tumor‐Specific Cd8+ T Cell Response, Hiep Khong May 2017

Peptide Vaccine Formulation Controls The Duration Of Antigen Presentation And Magnitude Of Tumor‐Specific Cd8+ T Cell Response, Hiep Khong

Dissertations and Theses (Open Access)

Despite remarkable progresses in vaccinology, therapeutic cancer vaccines have not achieved their full potential. We previously showed that the duration of antigen presentation critically affected the quantity and quality of T cell response and subsequent anti‐tumor efficacy. Here we describe L‐tyrosine amino acid‐based microparticles as a novel peptide vaccine adjuvant for the induction of tumor‐specific T cells. L‐tyrosine microparticles did not induce inflammasome activation, but instead extended antigen presentation time. The consequent prolongation in antigen presentation translated into prolonged T cell proliferation and superior numbers and anti‐tumor function of vaccination‐induced CD8+ T cells. Indeed, prolonging antigen presentation by repeated injection …


Novel Possibilities For The Treatment And Prevention Of Cutaneous Leishmaniasis, Eva A. Iniguez Jan 2017

Novel Possibilities For The Treatment And Prevention Of Cutaneous Leishmaniasis, Eva A. Iniguez

Open Access Theses & Dissertations

Protozoan parasites from the genus Leishmania cause broad clinical manifestations known as leishmaniasis, which affect millions of people worldwide. Cutaneous leishmaniasis (CL) is mainly caused by either Leishmania major or L. tropica parasites, which produce localized cutaneous ulcers, often leading to scarring and social stigma. Currently, the disease has reached hyperendemicity levels in the Middle East due to conflict and human displacement and is one the most common forms of the disease in the Old World. Furthermore, the first choice of treatment in that region continues to be pentavalent antimonials, which are costly and highly toxic, and current vector control …


Utilization Of Cholera Toxin B As An Adjuvant For The Subunit Pspa Vaccine, Provides Effective Protection Against Streptococcus Pneumoniae Challenge, Daniel R. Pinho Aug 2016

Utilization Of Cholera Toxin B As An Adjuvant For The Subunit Pspa Vaccine, Provides Effective Protection Against Streptococcus Pneumoniae Challenge, Daniel R. Pinho

Seton Hall University Dissertations and Theses (ETDs)

Streptococcus pneumoniae is a prevalent human pathogen associated with pneumonia. It is estimated that approximately 1 million people around the world die each year, specifically with young children and the elderly comprising a significant portion. Currently, antibiotics can treat the infection but individuals such as the young or elderly are more susceptible to bodily damage from symptoms, such as pneumonia, meningitis, and sepsis, thus require more preventive measures. As a result, vaccinations are a key solution to providing effective protection against infectious pathogens. Presently, two vaccinations exist in the market: PPSV23 and PCV13, which only protect against …

Coccidiosis continues to be a great challenge to the poultry industry all over the world and in broiler breeders vaccination with live oocysts of Eimeria has been widely adopted as a control measure. Broiler breeders are usually subjected to feed restriction during their early growth however no studies have been undertaken on the effects of vaccination in birds whose feed has been restricted in this manner. The objective of this study was to assess the level of protection acquired by broiler breeder chickens when immunized at day-old with live eimerian oocysts and given a restricted diet. Effects upon growth and …


Hiv Vaccines: Progress, Limitations And A Crispr/Cas9 Vaccine, Omar A. Garcia Martinez May 2016

Hiv Vaccines: Progress, Limitations And A Crispr/Cas9 Vaccine, Omar A. Garcia Martinez

Biology: Student Scholarship & Creative Works

ABSTRACT: The HIV-1 pandemic continues to thrive due to ineffective HIV-1 vaccines. Historically, the world’s most infectious diseases, such as polio and smallpox, have been eradicated or have come close to eradication due to the advent of effective vaccines. Highly active antiretroviral therapy is able to delay the onset of AIDS but can neither rid the body of HIV-1 proviral DNA nor prevent further transmission. A prophylactic vaccine that prevents the various mechanisms HIV-1 has to evade and attack our immune system is needed to end the HIV-1 pandemic. Recent advances in engineered nuclease systems, like the CRISPR/Cas9 system, have …

Current research in virology is changing public conceptions about vaccines and infectious disease. The University of Nebraska State Museum collaborated with research virologists, science writers, artists and learning researchers to create public outreach materials about viruses and infectious disease. The project, funded by the National Institute of Health’s SEPA program, developed comics, a book with Carl Zimmer, and other materials and programs. The project launched three kinds of learning research: 1) a survey of Nebraska adults on their opinions about vaccines and infectious disease; 2) a study comparing the mental models of viruses, vaccines and infection from virologists, teachers, and …


Characterization Of Induced Rnai Silencing Of Vaccinia Virus Essential Genes, Kewa Jiang May 2016

Characterization Of Induced Rnai Silencing Of Vaccinia Virus Essential Genes, Kewa Jiang

Honors Scholar Theses

Vaccinia virus (VACV) is a large double-stranded DNA virus and the prototypical member of the family Poxviridae and is most notable for its use as the vaccine that eradicated smallpox (variola virus). More recently, VACV has been used to develop recombinant vaccines and immunotherapies. However, many of these processes require VACV replication to be tightly controlled. RNA interference (RNAi) is a powerful tool for in vitro silencing of mRNAs that are complementary to 19-21 base pairs (bp) of double-stranded RNA (dsRNA). This project outlines the design and preliminary analysis of two inducible RNAi silencing constructs targeting multiple VACV essential genes …


Investigating The Effects Of Increasing Anti-Ama1, Anti-Msp1, And Anti-Msp2 In Preventing Malaria Incidence, April Skipper Apr 2016

Investigating The Effects Of Increasing Anti-Ama1, Anti-Msp1, And Anti-Msp2 In Preventing Malaria Incidence, April Skipper

Selected Honors Theses

Malaria is a life-threatening illness that 3.2 billion people, half of the world's population, are at risk of contracting. In 2015, there were 214 million malaria cases and 438,000 deaths caused by the disease. It is caused by Plasmodium parasites which infect humans through the bite of the Anopheles mosquito. The four species of Plasmodium that are known to cause malaria are P. falciparum, P. vivax, P. ovale, P. malariae, and P. knowlesi. The symptoms of malaria greatly resemble symptoms of a common cold, so accurate diagnosis can be a challenge. Symptoms commonly include fever, headache, …


Antibody-Mediated Immunity To Vibrio Cholerae At Epithelial Surfaces, Kara Jeanette Levinson Jan 2016

Antibody-Mediated Immunity To Vibrio Cholerae At Epithelial Surfaces, Kara Jeanette Levinson

Legacy Theses & Dissertations (2009 - 2024)

Vibrio cholerae, the causative agent of the severe diarrheal disease cholera, has an estimated worldwide disease burden in the millions and remains a significant public health threat. Immunity to V. cholerae is primarily antibody-mediated and though V. cholerae colonization evokes a mucosal immune response, it is the secretory IgA (SIgA) antibodies produced against bacterial surface antigens, specifically lipopolysaccharide (LPS) that confer protective immunity. SIgA antibodies are thought to function by inhibiting colonization by cross-linking and agglutination of pathogens, thereby limiting access to the epithelium, a process known as immune exclusion. Recent studies in other enteric pathogens have demonstrated that SIgA …

The Hot Zone And The Cold War, Peter Nichols Jul 2014

The Hot Zone And The Cold War, Peter Nichols

Colby Magazine

It was a time when, in the nation's schools, drills for nuclear war were as frequent as fire drills- when Americans and their Soviet counterparts lived with a constant fear of imminent worldwide destruction. "You had a cultural mindset that was apocalyptic," said Robert S. Weisbrot, Christian A. Johnson Distinguished Teaching Professor of History at Colby, "that believed you could not guarantee that your wonderful suburban home and family and community...would survive ten more seconds."

"It was not simply a matter of two countries that are adversaries building up weapons," said Weisbrot. "Each saw the other as the incarnation of …


Sa-4-1bbl As A Platform To Develop Adjuvant Systems For Prophylactic And Therapeutic Vaccines., Gunes Dinc 1984- May 2014

Sa-4-1bbl As A Platform To Develop Adjuvant Systems For Prophylactic And Therapeutic Vaccines., Gunes Dinc 1984-

Electronic Theses and Dissertations

Vaccines against infectious diseases are one of the most critical accomplishments in modern medicine. Despite significant progress in vaccinology, there is still a dire need for developing vaccines against various acute and chronic infections and cancer. In general, vaccines are categorized as prophylactic, given to healthy individuals to prevent disease, and therapeutic, administered to people who already have disease. As such, the nature, quality, and quantity of immune responses required for the efficacy of these two types vaccines are different. Prophylactic vaccines against infectious diseases primarily rely on the generation of neutralizing high titers of antibody for their efficacy. These …


Modulation Of Vaccine-Induced Responses By Anthelmintic Treatment In Ponies, Emily Rubinson Jan 2014

Modulation Of Vaccine-Induced Responses By Anthelmintic Treatment In Ponies, Emily Rubinson

Theses and Dissertations--Medical Sciences

Vaccines and anthelmintics induce an inflammatory response in equids. Since they are commonly given concurrently, it is practical to study any interaction between them. This study evaluated whether IVM and PYR would modulate the acute phase inflammatory response, the systemic gene expression of pro-inflammatory cytokines, and vaccine-specific titers induced by WNV, EHV, and KLH vaccines. Naturally-infected, yearling ponies were sorted by gender, then fecal epgs. They were randomly assigned to three treatment groups: IVM, PYR, and control. All ponies received vaccinations intramuscularly on days 0 and 29. Whole blood, serum, and plasma samples were collected 1, 3, and 14 days …

Immunoproteomic Analysis Of Proteins Expressed By Two Related Pathogens, Burkholderia Multivorans And Burkholderia Cenocepacia, During Human Infection., Minu Shinoy, Ruth Dennehy, Lorraine Coleman, Stephen Carberru, Kirsten Schaffer, Máire Callaghan, Sean Doyle, Siobhan Mcclean

Articles

Burkholderia cepacia complex (Bcc) is an opportunistic bacterial pathogen that causes chronic infections in people with cystic fibrosis (CF). It is a highly antibiotic resistant organism and Bcc infections are rarely cleared from patients, once they are colonized. The two most clinically relevant species within Bcc are Burkholderia cenocepacia and Burkholderia multivorans. The virulence of these pathogens has not been fully elucidated and the virulence proteins expressed during human infection have not been identified to date. Furthermore, given its antibiotic resistance, prevention of infection with a prophylactic vaccine may represent a better alternative than eradication of an existing infection. We …


Mucin Associated Surface Protein Synthetic Peptide As A Novel Vaccine Candidate Against Chagas Disease, Carylinda Serna Jan 2013

Mucin Associated Surface Protein Synthetic Peptide As A Novel Vaccine Candidate Against Chagas Disease, Carylinda Serna

Open Access Theses & Dissertations

Trypanosoma cruzi is an intracellular protozoan parasite and the etiological agent for Chagas disease. Chagas is endemic in Latin America affecting 18-20 million people. However, currently worldwide increasing numbers of the disease are being seen due to migration and globalization. This neglected disease causes significant morbidity, mortality, and an economic burden. There are no known vaccines and the only currently available drug is Benznidazole, but its effects are controversial. Nonetheless, a therapeutic or prophylactic vaccine is of urgent need to alleviate this disease. In this study we present an experimental approach using a synthetic peptide-based vaccine against T. cruzi. The …


Neutralizing Antibodies Against The Ricin Toxin Binding Subunit (Rtb), Anastasiya Yermakova Jan 2013

Neutralizing Antibodies Against The Ricin Toxin Binding Subunit (Rtb), Anastasiya Yermakova

Legacy Theses & Dissertations (2009 - 2024)

Ricin is a toxin that is naturally produced by the seeds of the castor bean plant Ricinus communis, and is part of a family of A-B toxins that includes Shiga, cholera, and anthrax toxins. The toxin consists of two subunits, RTA and RTB, which are linked by a disulfide bond. RTA is an RNA N-glycosidase that selectively targets and inactivates 28S ribosomal RNA, thereby arresting protein synthesis and leading to cell death. RTB is a galactose/ N-acetylgalactosamine-specific lectin that mediates attachment, entry, and intracellular trafficking of ricin in host cells. Currently, there is no approved vaccine or therapeutics available against …


Defining A Role For Inducible Heat Shock Protein 70 (Hsp70i) In Mediating Autoimmune Vitiligo, Jeffrey Alan Mosenson Jan 2013

Defining A Role For Inducible Heat Shock Protein 70 (Hsp70i) In Mediating Autoimmune Vitiligo, Jeffrey Alan Mosenson

Dissertations

Vitiligo is an autoimmune disease characterized by destruction of melanocytes, leaving 0.5% of the population with progressive depigmentation. Current treatments offer limited efficacy. Observations that heat shock proteins (HSPs) can serve as adjuvants in antitumor vaccines first suggested to us a link between HSPs and stress-induced vitiligo. Such proteins are marvelously well conserved throughout evolution, which has placed them in the spotlight for helping to understand the intriguing relationship between infection and immunity. Intracellularly, inducible heat shock protein 70 (HSP70i) is upregulated by stress and helps protect cells from undergoing apoptosis. In times of stress, melanocytes will secrete antigen bound …

Immunoproteomics: The Key To Discovery Of New Vaccine Antigens Against Bacterial Respiratory Infections, Ruth Dennehy, Siobhan Mcclean

Articles

The increase in antibiotic resistance and the shortage of new antimicrobials to prevent difficult bacterial infections underlines the importance of prophylactic therapies to prevent infection by bacterial pathogens. Vaccination has reduced the incidence of many serious diseases, including respiratory bacterial infections. However, there are many pathogens for which no vaccine is available and some vaccines are not effective among all age groups or among immunocompromised individuals. Immunoproteomics is a powerful technique which has been used to identify potential vaccine candidates to protect against pathogenic bacteria. The combination of proteomics with the detection of immunoreactive antigens using serum highlights immunogenic proteins …


Enhancing The Immune Response Through Ikkbeta-Induced Activation Of Nf-Kappab, Emily Hopewell Apr 2012

Enhancing The Immune Response Through Ikkbeta-Induced Activation Of Nf-Kappab, Emily Hopewell

USF Tampa Graduate Theses and Dissertations

Nuclear factor-κB (NF-κB) is one of the main regulators of inflammatory and immune responses. It is a family of transcription factors composed of five members: RelA, RelB, cRel, NF-κB1 (p105/p50), and NF-κB2 (p100/p52). Homo- and hetero-dimers of family members are inhibited by inhibitor of &klappaB (IκB) family members and activated by IκB kinase (IKK) family members. The IKK family is comprised of IKKα, IKKΒ, and IKKγ. The focus of my dissertation delves into the role of NF-κB activation by IKKΒ in both an immunotherapy setting and its role in T cell mediated anti-tumor immune responses.

A central focus of immunotherapy …

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 …


Membrane-Bound Immunomodulators As Adjuvants In A Cell Culture-Based Avian Influenza Vaccine, David Daniel Fischer Jan 2012

Membrane-Bound Immunomodulators As Adjuvants In A Cell Culture-Based Avian Influenza Vaccine, David Daniel Fischer

Wayne State University Dissertations

Inactivated viral vaccines often generate suboptimal immune responses. Adjuvants are incorporated into vaccines to increase their immunogenicity, however currently available adjuvants have shortcomings which have limited their use in human and veterinary medicine. This necessitates the development of new adjuvants and delivery systems. Cytokines have been extensively tested as adjuvants in vaccines but challenges such as diffusion from antigen, short half-lives and production costs have been encountered. To address this, we developed a technology that efficiently produces inactivated, whole-virus influenza vaccine bearing membrane-bound cytokines. Tethering the cytokine to the antigen of interest keeps the immunomodulator in close contact with the …

This paper evaluates the consistency of the healthcare utilization results based on the modified intention to treat (MITT) analyses with the PP analyses. The MITT analyses include all infants receiving at least one dose of vaccine or placebo and follow-up begins after …


The Quest For An Aids Vaccine, Robert T. Schooley Jan 1988

The Quest For An Aids Vaccine, Robert T. Schooley

New England Journal of Public Policy

More than fifty thousand cases of AIDS have been reported in the United States since the disease wasfirst described in 1981. Many times this number of people are infected with human immunodeficiency virus (HIV), which has been identified as the agent responsible for the illness. The seriousness of the disease, coupled with the relatively rapid spread of HIV, has fueled the effort for development of an effective vaccine.

Much is now known about the life cycle of the virus, and about its structural components. This information, and information about methods of transmission of the virus, form the basis for a …
