Cryptococcal Meningitis In A Patient With Multiple Sclerosis On Fingolimod, Syed Hassan Amir, Teena Mathew

North Texas Research Forum 2025

Background: There are a host of pathogens that thrive only when the host is weakened enough to be susceptible – Cryptococcus is one such organism that causes fatal meningitis, primarily in HIV patients. Those immunocompromised by other means are also susceptible. Among them, patients with multiple sclerosis (MS) pose a significant challenge as what may initially be considered an MS flare could mask a serious underlying infection. Objective: This case study discusses an MS patient on Fingolimod, an immunosuppressant, that likely made them vulnerable to cryptococcal meningitis. Pathogenesis: Cryptococci are encapsulated yeast that enter the body via inhalation of spores …

Disseminated Fusarium Infection To Lung, Liver, And Brain In An Acute Promyelocytic Leukemia (Apml) Patient; A Case Report, Lane F. Smith, Alexandria Goyer, Ali Al-Nahi, Neil Bhangoo, Yi Lei, Zara Soomro, Amy Nguyen-Pham, Tasaduq Mir

North Texas Research Forum 2025

Background: Disseminated fusarium, primarily affecting immunocompromised individuals, is associated with persistent fevers, rash, and lung involvement. Despite interventions, mortality rate remains high, exceeding 75% for disseminated disease. There are only 26 documented cases worldwide between 1974 and 2022 with CNS involvement. This case highlights a rare presentation of disseminated fusarium infection involving the lungs, liver, and brain in a 53-year-old male with acute promyelocytic leukemia (APL), highlighting critical diagnostic and therapeutic challenges. Case Presentation: A 53-year-old male with a history of APL with PML/RARA fusion t (15,17) after chemotherapy presented with persistent fevers, rash, encephalopathy, and severe sepsis while undergoing …

Fatal Overlapping Cns Infections: Radiologic Correlates Of Ventriculitis, Encephalitis, And Meningitis​, Jesse F. Simon, Sara Darwish, Stephanie Nagy, Richard Shalmiyev, David Kosoy, Bryan Rubio, Gustavo Pantol, Mauricio Danckers

East Florida Division GME Research Day 2025

Introduction: This case study explores an uncommon triad of encephalitis, ventriculitis, and meningitis complicated by ischemic strokes and seizures in a COVID-19-positive patient. Prior studies suggest that bacterial meningitis and encephalitis can lead to cerebral infarctions due to inflammation and vascular injury.1,2,5 Ventriculitis, in particular, is rarely observed and typically is seen as a severe complication of meningitis, and can be managed with neurosurgical interventions such as CSF shunt placement, ventricular drains, or other intracranial devices.3,4 The simultaneous presentation of all three conditions in a single patient is rare and poses significant challenges from a diagnostic and management standpoint.

The Role Of Horizontal Gene Transfer In Antibiotic Resistance Amidst Prevalent Community And Healthcare-Associated Mrsa Rates, Gabrielle Nascimento

Honors College Theses

In recent decades, cases of community-acquired MRSA (CA-MRSA) and healthcare-associated MRSA (HA-MRSA) have been on the rise. The ability of antibiotic resistance to transfer between microorganisms greatly expands its threat to the effective treatment and containment of bacterial infections. The mecA gene is found on a mobile cassette within the Staphylococcal cell and encodes for PBP2a, an alternate version of penicillin-binding protein (PBP) with less binding affinity for β-lactam antibiotics, increasing resistance to the effects of antibiotics. The goal of this research is to investigate the horizontal transfer of the mecA gene between various Staphylococcus species as well as to …

Development Of A Proposed Selective Medium For The Isolation And Differentiation Of P. Sordellii, Dimyana Bottros

Honors Undergraduate Theses

Clostridium, a genus of anaerobic, spore-forming bacteria, includes clinically and ecologically significant species like Clostridium difficile and Paeniclostridium sordellii. C. difficile causes antibiotic-associated colitis, while P. sordellii is linked to fatal infections and spontaneous abortions. Recent studies found both species in marine sediments, suggesting their role in environmental and wildlife health disturbances, including the 2013 mass mortality of over 300 manatees in the Indian River Lagoon. However, isolating and differentiating P. sordellii is challenging due to the lack of selective media optimized for its growth. This thesis proposes a novel selective medium tailored to P. sordellii’s physiological …

Diversity Within Species: Mechanisms, Evolution And Implications In Bacterial Disease, Kathryn R. Piper

Electronic Theses & Dissertations (2024 - present)

The Gram-positive bacterium Staphylococcus aureus and the Gram-negative bacterium Escherichia coli are ubiquitous commensal and opportunistic pathogens. In humans, S. aureus is commonly found on the skin and mucus membranes, and is known to cause infections in the skin, bloodstream and brain. E. coli is a normal part of the gut microbiota in humans and can cause intestinal and extraintestinal infections alike. S. aureus and E. coli pose global threats to public health, due to the high morbidity and mortality of invasive strains. The wide range of infections they cause in humans and other animals are exacerbated by the presence …

Identifying The Role And Influence Of Interleukin-27 On The Neonatal Immune Response, Jordan Kane Vance

Graduate Theses, Dissertations, and Problem Reports (ETD)

The first month of life is a critical and vulnerable developmental stage, characterized by a heightened risk of life-threatening infections. Each year, 1.3 million newborns succumb to neonatal bacterial sepsis. The immune system during the neonatal period has unique features that lead to inefficiencies at clearing infection. Early life immunity is characterized by a Th2-biased profile with decreased IL‑12, IFN-γ, and TNF-α, along with increased IL‑6 and IL‑23. Additionally, IL‑27, an immunosuppressive cytokine, is also elevated during this period and further contributes to susceptibility to infection. Early diagnosis and intervention are critical in administering effective care in newborns and there …
