Early Intervention In Helminth Infections: Investigating Albendazole’S Effects On C. Elegans Egg Hatch Rate And Health, Giselle Domingo Diaz

Student Scholar Symposium

Over 1.5 billion of the poorest people are infected with soil-transmitted helminths (STH) such as whipworm, hookworm, and Ascaris which have devastating effects on human growth, nutrition, and cognition, perpetuating the cycle of poverty. The World Health Organization only approves four anthelmintic drugs to treat STH for mass drug administration (MDA), with Albendazole being the drug of choice. Due to these drugs only having two mechanisms of action, resistance to these drugs has been reported over the years. We aim to better understand STH susceptibility to drugs at multiple points in their life stage. Previously, the effects of Albendazole and …

Investigating The Effects Of Albendazole On The Hatch Rate And Motility Of C. Elegans Eggs, Jennifer Domingo Diaz, Emma Duerson

Student Scholar Symposium

Over 1.5 billion individuals a year are infected with soil-transmitted helminths (STH) such as whipworm, hookworm, and Ascaris. These infections have detrimental effects on human growth, nutrition, and cognition leading to a cycle of poverty. Currently, The World Health Organization (WHO) recognizes four drugs to treat STH for mass drug administration which consist of two mechanisms of action. These fall into two classes, nicotinic acetylcholine receptor agonists and benzimidazoles. Albendazole, the drug of choice, is a beta-tubulin inhibitor that induces the immobilization and death of STH (Malik and Dua, 2023). The widespread use of these drugs and the limited mechanism …

Understanding Lyme Iaci: Implications For Camp Nurses, Mary Tobin

CompassPoint

Lyme Infection-Associated Chronic Illness (Lyme IACI) is a term adopted by the U.S. National Academies of Sciences, Engineering, and Medicine (NASEM) to describe persistent, often debilitating symptoms that follow Lyme disease infection. Affecting an estimated 10–20% of individuals treated for Lyme disease, Lyme IACI includes fatigue, musculoskeletal pain, cognitive dysfunction, and sleep disturbances that can last months or even years despite standard antibiotic therapy (NASEM, 2025). Unlike acute Lyme disease, Lyme IACI is not well understood and lacks validated diagnostic tools or biomarkers, making it a challenge to diagnose or treat for clinicians and caregivers—especially those working with children in …

Introduction. Six to seven million individuals are infected with Trypanosoma cruzi, the causative agent of Chagas disease. With 12,000 deaths annually, chronic Chagas disease remains a significant global health challenge due to persistent vector transmission, increasing non-vector transmission and limited therapeutic options. Chronic Chagas cardiomyopathy is a leading cause of morbidity and mortality, yet the underlying mechanisms remain poorly understood.Gap Statement. Since its initial description more than 100 years ago, research efforts into the cardiomyopathy found in chronic Chagas disease have primarily focused on the contributions of immune cells, cardiomyocytes and cardiac fibroblasts, leaving a significant gap in understanding the …

Cerebral Malaria In Chad- A Case Report Series, Megan W. Szobody, Blaise Djomg Yang, Noel Johnson, Kelsey Potter-Baker

Research Colloquium

Malaria is a serious disease caused by various species of the Plasmodium genus. Among these, Plasmodium falciparum is widely considered the most dangerous, due to its ability to infect both young and mature red blood cells (RBCs). Malarial disease, caused primarily by P. falciparum, is a major cause of morbidity and mortality in Sub-Saharan Africa, and notably in Chad, accounting for over 10,000 deaths each year and with an incidence rate of over 3 million. Anyone can acquire falciparum malaria after being bitten by infected anopheles mosquitoes, but in pregnant women and young children, this disease is often deadly. A …

Host, Microbiome, And Parasite: How Apicomplexan Microorganisms Interact With Gut Microbiota, Senia Bu, Andrew T. Ozga

Mako: NSU Undergraduate Student Journal

The gut microbiome, a complex ecosystem of microorganisms residing in the human gastrointestinal tract, plays a crucial role in maintaining overall health. It functions in immune system regulation, digestion, and protection against pathogens. Apicomplexan parasites, such as Toxoplasma gondii, Plasmodium spp., and Cryptosporidium spp., are major pathogens that can significantly disrupt the gut microbiota, leading to alterations in microbial composition and function. This review explores the bidirectional interactions between Apicomplexan parasites and the gut microbiome, focusing on how these parasites influence microbial diversity, immune responses, and host metabolism. It examines the mechanisms by which infection-induced inflammation, altered …

Integrating Clinical History, Imaging, And Serologic Testing For The Accurate Diagnosis Of Neurocysticercosis: A Case Report, Jedediah Bondy, Paul Dobria, Dillon Woody, Bryan Scott

Advances in Clinical Medical Research and Healthcare Delivery

Neurocysticercosis is a parasitic infection caused by the cestode Taenia solium, in which pigs serve as the definitive hosts. Humans can become accidental intermediate hosts through the ingestion of food contaminated with Taenia solium eggs via fecal-oral transmission. Once ingested, the eggs of Taenia solium hatch into larvae, which then migrate through the bloodstream and disseminate across various organs, including the central nervous system (CNS). In this case, a 40-year-old male from Mexico with a known history of seizure disorder presented to the emergency department with altered mental status. He had been told by a physician in his native …

Spatially Resolved Transcriptomic Profiles Of Placental Cell Populations In Placental Malaria, Corina A. Mong

Undergraduate Honors Theses

Malaria remains a prevalent infectious disease that continues to cause disease-related morbidity and mortality. Despite preventative efforts, malarial pregnancies still cause birth complications, therefore emphasizing the necessity to study these adverse outcomes in malarial pregnancy. Malaria in pregnancy can lead to placental malaria (PM), which is the presence and accumulation of Plasmodium-infected red blood cells in the placental intervillous space (IVS). Even after treatment, past PM (presence of hemozoin crystals from the parasite in the placenta) can cause a chronic inflammatory response. We predicted that the activation states of the maternal monocytes and fetal macrophages differ within the placenta and …

Targeting Detoxifying Enzymes In The Lymphatic Filariasis Vector: An In Silico Study On Curcumin, Camphor, And Menthol, Rizal Subahar, Rawina Winita, Surya Dwira, Gulshan Fahmi El Bayani

Indonesian Journal of Medical Chemistry and Bioinformatics

Vector control remains a critical component in the prevention of lymphatic filariasis, a disease transmitted by insect vectors. Natural compounds such as curcumin, camphor, and menthol are being explored for their bio-insecticidal properties due to their potential to inhibit key detoxification and neurological enzymes in insects, including acetylcholinesterase (AChE), glutathione S-transferase (GST), and cytochrome P450 oxidases (CYP450). A molecular docking study using SwissDock was conducted to evaluate the interaction of curcumin, camphor, and menthol with AChE, GST, and CYP450 enzymes. Binding affinity (ΔG), hydrogen bonding, and active site interactions were analyzed to assess the inhibitory potential of each compound. Curcumin …

Tickborne Colpodella Species Infections: Time For A New Integrated Approach To Understand Transmission And Pathogenicity, T. Y. Sam-Yellowe, Trinity Nims, Sona Qaderi, Mary M. Asraf

Biological, Geological, and Environmental Faculty Publications

Colpodella species are free-living predatory protists that prey on algae, ciliates and bodonids using myzocytosis. Colpodella species have been reported in human and animal infections. Polymerase chain reaction (PCR) using primers targeting 18S rRNA genes of Cryptosporidium and piroplasms have identified Colpodella species in arthropods, host blood and feces, demonstrating the phylogenetic closeness of Colpodella species to the apicomplexa. However, in human, animal and arthropod hosts, the life cycle stages of Colpodella are unknown. In this literature review, we provide an overview of the widespread occurrence of Colpodella species in ticks, and pathogenicity in humans and animals. We discuss methods …

Biomarkers That Could Explain Parasite-Induced Behavioral Alterations In The Golden Shiner (Notemigonus Crysoleucas) – Posthodiplostomum System, Laura D. Nicolas

All HCAS Student Capstones, Theses, and Dissertations

Trophically transmitted parasites require an intermediate host to be consumed and often manipulate host phenotype (i.e., morphology, physiology, and/or behavior) to increase predation risk by definitive hosts. Posthodiplostomum is a trematode with a complex life cycle involving snails as first hosts, fish as second intermediate hosts, and piscivorous birds as definitive hosts. In fish hosts, Posthodiplostomum infection has been linked to increased predation, suggesting suppression of antipredator behaviors. However, the specific physiological pathways remained unexplored and changes in the host’s neural, endocrine, and immune systems could be involved. Thus, I examined whether Posthodiplostomum infection intensity was associated with brain serotonin …

A ‘Fluke’ Diagnosis: Suspecting Fascioliasis As A Rare Cause Of Hepatic Abscess, Tharun Shyam, Rosa Lora, Sharanya Kaushik, Jessica Chung, Monica Ghitan, Christina Coyle

Journal of Community Hospital Internal Medicine Perspectives

Hepatic abscess is a rare complication of fascioliasis, with fewer than 50 reported cases worldwide. The diagnosis requires a high degree of suspicion and is often identified after extensive investigation leading to delays in treatment. With this case report, we aim to highlight the need for a higher index of suspicion in non endemic regions like the USA, especially in cities with large immigrant populations. Given the ease and success rates of treatment with oral triclabendazole, the morbidity from unnecessary invasive testing and disease burden is preventable with a thorough evaluation and targeted clinical assessment.

A Review On Treatment, Prevention, And Research Of Worldwide Parasitic Disease: Toxoplasmosis, Hannah Skinner

All Theses

Toxoplasmosis is a worldwide, yet often overlooked, parasitic disease caused by the protozoan parasite, Toxoplasma gondii. The parasite is capable of infecting humans and almost all warm-blooded vertebrates. Over a million people are infected in the United States with toxoplasmosis each year. Most infections are asymptomatic but severe cases can lead to vision impairment, neurological disorders, and congenital birth defects. T. gondii is transmitted through undercooked meat, infected feline feces, or contaminated water and soil. The burden of T. gondii infection is most notable in livestock, felines, and immunocompromised humans. Despite being a widespread disease, toxoplasmosis is neglected in …

The Role Of Myosin L In The Survival Of Toxoplasma Gondii And The Importance Of Mlc1 For In Vitro And In Vivo Myosin F Motility, Victoria K. Yi

Honors Scholar Theses

My thesis discusses the work that I have conducted on two myosins in Toxoplasma gondii, which is an obligate intracellular parasite that has chronically infected around 10% of the American population. It causes toxoplasmosis and severe health consequences for individuals with compromised immune systems or when infections occur in utero. However, immunocompetent individuals are asymptomatic or present with subclinical symptoms. In the Heaslip lab, I investigated two myosins in the parasite: Myosin L and Myosin F. MyoL is an uncharacterized motor that localizes at the apical end of the parasite. It was shown to be important for parasite …

Thymosin Beta-4: A Novel Treatment For Acanthamoeba Keratitis, Victoria A. Murphey

All Theses

Acanthamoeba keratitis (AK) is a severe corneal infection caused by the free-living amoeba, Acanthamoeba. Both stages of its life cycle (trophozoite and cyst) cause infection, primarily in contact lens wearers. It is often misdiagnosed, leading to delayed treatment and poor clinical outcomes. Current treatment options for AK rely on anti-amoebic agents that are toxic to corneal epithelial cells. Further, no single drug can eliminate both forms of the amoeba. Approximately 30% of all AK infections require a corneal transplant.

Thymosin beta-4 (Tβ4) is a G-actin binding protein synthesized in almost all human cells, including corneal epithelial cells. Tβ4 exhibits …

Challenges In Public Health: The Diagnosis And Treatment Of Crusted Scabies, Marshall Hall, Alyssa Forsyth, Wenquin Du, Michael Carletti, Stephen Weis

North Texas Research Forum 2025

Introduction: Common scabies is a parasitic dermatologic condition that often presents as an extremely pruritic rash. A rare and highly contagious variant of common scabies is crusted scabies, formerly known as Norwegian scabies. While infection with common scabies typically involves 10 to 20 mites, individuals with crusted scabies are burdened with thousands to millions of mites. Crusted scabies is characterized clinically by hyperkeratotic papules and plaques, most commonly on the palms and soles. Due to the variety of presentations seen in scabies, it can be difficult to diagnose. Case presentations: We present 4 cases of crusted scabies. An 89-year-old male …

Schistosoma Mansoni Infection Causes Consistent Changes To The Fecal Bacterial Microbiota Of Mice Across And Within Sites, Mariam A. Mhanna, David T. Gauthier, Lisa M. Shollenberger

Biological Sciences Faculty Publications

Eggs of Schistosoma mansoni are produced by adult female worms in mesenteries of infected hosts. Eggs can cross the intestinal barrier and form granulomas in the tissue or breach and exit the host through fecal excretion. These interactions may affect the host microbiome assemblages. Given the potential for schistosomal alteration of host gut microbiome and subsequent effects on the fecal bacterial composition, it is important to conduct controlled microbiome studies on model animals. While pursuing these studies, it is important to take into account the different conditions in which microbiome studies are conducted and their consequent impacts on variability and …
