Characterization Of A Plasmid-Based Dna Vaccine For Simian Immunodeficiency Virus, Priya Sanipara May 2020

Characterization Of A Plasmid-Based Dna Vaccine For Simian Immunodeficiency Virus, Priya Sanipara

Honors Theses

Described as one of the world’s worst pandemics, HIV (Human Immunodeficiency Virus) infects millions of people each year and is the cause for AIDS (Acquired Immunodeficiency Syndrome). Despite the development of vaccines for numerous infectious diseases such as polio, small pox, and influenza, a vaccine for HIV remains elusive due to the virus’s high mutation rate and ability to evade the immune system. HIV causes depletion of CD4+ lymphocytes, resulting in a weakened immune system. However, the development of a plasmid-based DNA vaccine approach may help revolutionize vaccine development for HIV due to its ability to confer cellular and humoral …


Design And Synthesis Of Novel Analogs As Potential Antitubercular Agents, Peggy Mccluggage May 2020

Design And Synthesis Of Novel Analogs As Potential Antitubercular Agents, Peggy Mccluggage

Honors Theses

Tuberculosis (TB) is an infectious, airborne disease which primarily infects the lungs. One-third of the world’s population is currently estimated to be infected with Mycobacterium tuberculosis (Mtb), the causative agent for TB [1]. Current treatment for this disease requires at least six months of taking multiple antibiotics with undesirable side effects [2]. Difficulty in complying to this regimen as well as the prevalence of HIV/AIDS has led to antimicrobial resistance seen in Mtb. In order to combat the Multi-Drug Resistant and Extensively-Drug Resistant strains of the disease-causing bacteria, preventative care and novel antibiotics are urgently needed [3]. The purpose for …


How Misinformation And Mistrust Compound The Threat Of Epidemics, William Boyd May 2020

How Misinformation And Mistrust Compound The Threat Of Epidemics, William Boyd

Honors Theses

This thesis was conducted to study the effects of misinformation and medical mistrust on the public health field. I use the events of the Chapare Virus outbreak in Bolivia in the summer of 2019 and the public dialogue during that time period to discuss these themes. I used data from market survey's in La Paz, newspaper articles from Página Siete, and Tweets from the time period of the outbreak. My findings suggest that misinformation and medical mistrust affected public health measures, which has major implications for the way the public health field should address future public health events.


Fatty Acid Mediated Alterations In Biofilm Formation With Vibrio Cholerae, Isabel Gray May 2020

Fatty Acid Mediated Alterations In Biofilm Formation With Vibrio Cholerae, Isabel Gray

Honors Theses

Vibrio cholerae is a Gram-negative bacterium known as a waterborne pathogen. It is often found in marine conditions and can infect humans through ingestion. V. cholerae is responsible for cholera, a disease characterized by profuse diarrhea, vomiting, and other dehydration symptoms. Ultimately, severe cases can cause extreme electrolyte imbalances, shock, and acute renal failure which lead to death in a short period of time. Annually, V. cholerae causes approximately 3 million cases of cholera and 100,000 deaths worldwide. V. cholerae can persist in motile and biofilm lifestyles under aquatic and host conditions, a unique biphasic lifestyle that contributes to Vibrio’s …


Molecular Characterization Of Wolbachia And Its Impact On The Microbiome Of Exotic And United States Ticks, Cailyn G. Bobo May 2020

Molecular Characterization Of Wolbachia And Its Impact On The Microbiome Of Exotic And United States Ticks, Cailyn G. Bobo

Honors Theses

Wolbachia endosymbionts are obligate intracellular bacteria in the phylum α-Proteobacteria. They infect approximately two-thirds of arthropods including insects and nematodes. These bacteria manipulate host reproductive biology through a series of mechanisms that include feminization of male progeny, parthenogenesis, male killing, and cytoplasmic incompatibility. These features make Wolbachia an effective agent of controlling insect populations, as previously reported in different mosquito species. Likewise, the bacteria have also shown promising ability to interfere with the ability of mosquitoes to transmit several viral pathogens. This study was conducted to fill an existing knowledge gap on the prevalence of Wolbachia in different tick species …


Assessing The Effect Of Bile And Oxygen Availability On The Redox Status Of Listeria Monocytogenes Strain F2365, Sukriti Bhattarai May 2020

Assessing The Effect Of Bile And Oxygen Availability On The Redox Status Of Listeria Monocytogenes Strain F2365, Sukriti Bhattarai

Honors Theses

Although bile is a bactericidal agent able to disrupt membrane structure and cellular homeostasis, including the induction of oxidative stress, Listeria can tolerate bile and also utilize it as a signal to enhance infection and virulence. Preliminary findings showed that under anaerobic conditions, exposure to bile significantly lowered the amount of oxidative damage present in bile-resistant strain F2365 cells. Similarly, Listeria further elicits an adaptive immune response, wherein pre-exposure of the bacterium to stress during food processing or in the host prior to entry into the intestine increases bile tolerance. Based on these previous studies, we hypothesized that bile induces …


Generating Zika Vaccine Candidates Using Nhumirim Virus As A Backbone, Mariam A. Atobiloye May 2020

Generating Zika Vaccine Candidates Using Nhumirim Virus As A Backbone, Mariam A. Atobiloye

Honors Theses

Zika virus (ZIKV) is a mosquito-transmitted flavivirus that is causing significant world-wide health concern. There are currently no treatments or vaccines available for this virus, thus, there is an urgent need to develop a safe and effective vaccine to combat ZIKV infection. Nhumirim virus (NHUV) is also a mosquito-transmitted flavivirus, but it is unable to infect humans and other vertebrate animals, making it an ideal candidate to develop chimeric viral vaccines against other disease-causing flaviviruses, such as ZIKV. In this study, we generated chimeric viruses by replacing envelope (E) gene in the genome of NHUV with ZIKV E gene, which …


The Effects Of Disease Contamination On Memory For Touched Objects In Older Adults, Jessica M. Runnels May 2020

The Effects Of Disease Contamination On Memory For Touched Objects In Older Adults, Jessica M. Runnels

Honors Theses

Recently it has been shown that individuals have better memory for objects that have been touched by an individual with a contagious disease relative to an individual with a non-contagious disease or who is healthy (Gretz & Huff, 2019). This pattern has been suggested to occur due to the activation of the Behavioral Immune System (BIS)—an avoidance-based system designed to thwart sources of potential pathogens. The BIS has been suggested to operate through an evolutionary-based mechanism in which avoidance of pathogens increases the likelihood of survival, increasing reproductive success. Given this approach, an important question is how the activation of …


Regulation Of Weak Acid-Dependent Cell Death By The Msaabcr Operon During Biofilm Formation Of Staphylococcus Aureus, Sarah-Elizabeth M. Polley May 2020

Regulation Of Weak Acid-Dependent Cell Death By The Msaabcr Operon During Biofilm Formation Of Staphylococcus Aureus, Sarah-Elizabeth M. Polley

Honors Theses

Staphylococcus aureus is a dangerous human pathogen and a leading cause of both nosocomial and community-associated infections. Infection by S. aureus is a growing health concern due to the emergence of antibiotic resistance and the capability to form robust biofilms. Major constituents of the biofilm extracellular matrix are demonstrated to be released via controlled autolysis of a subpopulation of the biofilm. As indicated in past studies, the programmed cell death (PCD) of S. aureus grown in a biofilm microenvironment is potentiated by the buildup of acetate, a byproduct of glucose metabolism, which causes cytoplasmic acidification. Furthermore, it has been shown …

“A Moral Imperative To Prevent Aids”: Race And Religion In Atlanta’S Aids Activism, 1981-1993, Madison Bailey

Honors Theses

The early years of the AIDS epidemic marked a tumultuous period of American history, calling into question the authority of doctors and the ability of scientists to cure disease. Already marginalized groups, such as gay men and intravenous drug users, appeared to be most vulnerable to a deadly virus with no cure or effective treatments. In the face of discrimination, activists rose up to provide necessary services for AIDS patients and advocate on their behalf. This activism uniquely characterized the early AIDS epidemic and permanently changed the field of biomedical research. The current historiography of AIDS activism tends to focus …

Serial dilutions were performed, and samples were plated on various culture media. Following incubation, counts of bacteria were determined. DNA was extracted from bacterial growth on plates from …


Investigating The Role Of The Etc In Listeria Monocytogenes During Ethanol Exposure, Amanda Fawcett Apr 2020

Investigating The Role Of The Etc In Listeria Monocytogenes During Ethanol Exposure, Amanda Fawcett

Honors Theses

To better understand how alcohol consumption negatively impacts our defenses against pathogens, I investigated how Listeria monocytogenes, a foodborne pathogen that can cause serious infections, responds to ethanol exposure. More specifically, I investigated the contribution of the electron transport chain (ETC), which involves different proteins to carry out respiration, in L. monocytogenes survival in ethanol. Survival assays were performed under different physiologically relevant conditions for wildtype bacteria and mutants deficient in ETC components. I found that ETC mutants, compared to wildtype bacteria, exhibited significantly altered ethanol survival in a manner sensitive to oxygen levels. This suggests that ETC plays a …

The Impact Of Vaccine Coverage And Exemptions On The Resurgence Of Vaccine Preventable Disease: A Review Of The Literature, Kara Costantino Apr 2020

The Impact Of Vaccine Coverage And Exemptions On The Resurgence Of Vaccine Preventable Disease: A Review Of The Literature, Kara Costantino

Honors Theses

Vaccinations are a safe and effective way to prevent the spread of disease. In recent years, vaccine coverage rates have declined while nonmedical exemption rates have increased. These changes have contributed to increased prevalence of vaccine preventable diseases. Declining vaccine coverage and increasing nonmedical exemptions are a threat to public health and the relationship between these factors needs to be understood. Clusters and outbreaks of vaccine preventable diseases have occurred as a result of more people declining vaccination. Factors that may incline someone to refuse vaccination include safety concerns, lack of trust, freedom of choice, decreased understanding for the need, …

Vaccinate Her? I Hardly Know Her!: Understanding Vaccine Hesitancy, Zachary M. Marcum Apr 2020

Vaccinate Her? I Hardly Know Her!: Understanding Vaccine Hesitancy, Zachary M. Marcum

Honors Theses

Vaccines are a first defense against highly communicable diseases such as measles. For vaccines to protect the population, a vast majority must be vaccinated to maintain herd immunity. Vaccine hesitancy is delaying vaccination from the suggested schedule or refusing vaccination outright. The hesitance is commonly portrayed as a lack of knowledge or scientific literacy. But highly educated people are still just as likely to be hesitant. The basis of hesitance is likely ethically similar to that of vaccination. Understanding the methods of the vaccine hesitant will better inform attempts to persuade them. Individuals have an obligation to the community to …


Systematic Review Of Integrating Care To Improve Quality Of Life Within Chronically Diseased Patients With Mental Illness, Brooke R. Goble Apr 2020

Systematic Review Of Integrating Care To Improve Quality Of Life Within Chronically Diseased Patients With Mental Illness, Brooke R. Goble

Honors Theses

Chronic disease and mental illness affects a multitude of individuals in the United States. Sufficient treatments exist for chronic diseases and mental illnesses, separately. However, a gap in care exists in individuals who have co-occurring conditions. The presence of one or more chronic conditions, or comorbidities, has been observed by several providers, yet there is a crucial need for integrated care in the case of chronically diseased individuals with mental illness. Increasing quality of life within this vulnerable population is a necessity. The purpose of this systematic review is to determine whether integrated care and collaboration between behavioral health and …

Give Me A Choice: Perceptions Of Freedom And The Anti-Vax Movement In Maine, Louisa Goldman Jan 2020

Give Me A Choice: Perceptions Of Freedom And The Anti-Vax Movement In Maine, Louisa Goldman

Honors Theses

While vaccination has proven to be an incredibly effective method of disease prevention, the growing ‘anti-vax’ movement threatens the population-level benefits conferred by widespread immunization. Recent findings indicate that anti-vax beliefs are not, as had been previously assumed, necessarily the result of scientific illiteracy but rather, are likely produced by intertwining social and situational contexts. With these considerations in mind, the goal of this study was to identify potential motivations underlying anti-vax behavior by performing a deep examination of anti-vax rhetoric, coupled with demographic and situational analyses. I focused specifically on the anti-vax community in Maine, with a special interest …


Naloxone Access And Opioid Use: A Theoretical Analysis, Caroline Dunsby Jan 2020

Naloxone Access And Opioid Use: A Theoretical Analysis, Caroline Dunsby

Honors Theses

Naloxone, commonly known by the brand name Narcan, is a medication that reverses the potentially fatal effects of an opioid overdose. Amidst the opioid epidemic that has taken tens of thousands of lives each year, many policies have been enacted to increase the public's access to naloxone, allowing non-medical personnel to save lives. There have been two distinct reactions to these policies. Those that support the policies state that harm reduction measures are necessary to save lives. Those that oppose the policies claim that by providing naloxone, states may be increasing risky opioid use - suggesting that naloxone leads to …

Antibiotic Resistant Bacteria Isolated From Michigan Birds - A High School Learning Experience, Cody Benfant Jun 2019

Antibiotic Resistant Bacteria Isolated From Michigan Birds - A High School Learning Experience, Cody Benfant

Honors Theses

Bacteria, extremely small prokaryotic cells, are everywhere throughout the world. One striking thing about bacteria is their size: comparing a 2-micrometer bacterial cell to a 6-foot-tall human is similar in scale to comparing a 6-foot-tall human to the distance between Chicago, IL and Denver, CO! Despite their small size, bacteria are found in almost every ecosystem and environment imaginable. From deep sea hydrothermal vents to the clouds miles in the sky, there are trillions of bacteria flourishing in all of Earth’s ecosystems, performing many important functions in global nutrient cycles. While the majority of bacteria are beneficial to humans, …

Modification Of Hiv-1 Protease Inhibitor Pharmacophore To Assess Anti-Malarial Properties, Margaret Ann Street May 2019

Modification Of Hiv-1 Protease Inhibitor Pharmacophore To Assess Anti-Malarial Properties, Margaret Ann Street

Honors Theses

For years, the human immunodeficiency virus type 1 (HIV-1) and malarial parasites have both been prevalent in sub-Saharan Africa. Coinfections of HIV-1 and malaria are common in areas of geographic overlap as both infections seem to increase the severity of the other. HIV-1 treatments have shown to decrease the Plasmodium infections resulting in a lower malarial incidence. HIV-1 protease inhibitors target a crucial step in the life cycle required for viral maturation and have demonstrated a lower level of resistance compared with other therapies. Recent studies have shown the treatment of HIV-1 with protease inhibitors has resulted in inhibitory effects …


Histone Deacetylase Inhibitors And Breast Cancer Metastasis: A Review And Exploration Of Hdac(I)S And Other Chemotherapeutic Agents, William E. Sistrunk May 2019

Histone Deacetylase Inhibitors And Breast Cancer Metastasis: A Review And Exploration Of Hdac(I)S And Other Chemotherapeutic Agents, William E. Sistrunk

Honors Theses

The traditional perspective of Histone Deacetylase enzymes is focused on their inherent epigenetic modification characteristics. While it is true that the histone modification these enzymes exhibit play a role in cancer and related diseases, Histone Deacetylase has a variety of non-histone targets. The non-histone targets include microtubules and are of specific interest because of the microtubules’ role in cell line differentiation, replication, apoptosis, and cancer metastasis. Using a variety of Histone Deacetylase Inhibitors (HDACi) and other chemotherapeutic compounds, our research group explored the HDACi effect on breast cancer cell lines. Our goal was to indicate the presence of HDACi cell-line …


Effects Of Mycoplasma Gallisepticum On Experimentally Infected Eastern Bluebirds (Sialia Sialis), Meredith A. Fry May 2019

Effects Of Mycoplasma Gallisepticum On Experimentally Infected Eastern Bluebirds (Sialia Sialis), Meredith A. Fry

Honors Theses

The bacterium Mycoplasma gallisepticum is an avian respiratory pathogen that causes inflammation and swelling of conjunctiva in domestic poultry and wild finches. In the past, severity of conjunctivitis symptoms has been used to quantify infection severity and host resistance. However, many songbirds function as hosts to M. gallisepticum but do not develop this symptom at all. The absence of conjunctivitis, as well as other clinical signs, hinders our understanding of M. gallisepticum infection in the songbird community because some species are responding very differently than others. One such species is the Eastern Bluebird (Sialia sialis), a common songbird of the …


Effects Of The Pathogen Mycoplasma Gallisepticum Transmission On Growth And Condition Of Eastern Bluebirds Nestlings (Sialia Sialis), Gurshan Kaur May 2019

Effects Of The Pathogen Mycoplasma Gallisepticum Transmission On Growth And Condition Of Eastern Bluebirds Nestlings (Sialia Sialis), Gurshan Kaur

Honors Theses

A critical aspect to understanding disease dynamics is to understand how transmission occurs between hosts. There are two basic modes of transmission: vertical and horizontal. Vertical transmission is the passage of a pathogen from mother to offspring before or during birth, whereas horizontal transmission occurs between an infected host to a susceptible host. Mycoplasma gallisepticum (MG) is a common bacterial pathogen of poultry that causes respiratory disease. Infection of MG often results in weight loss, slowed growth rate, and increased mortality. Both vertical and horizontal transmission of MG have been found to occur in poultry. In the mid-90s, MG underwent …
