Cytomegalovirus As A Potential Trigger For Acute Coronary Syndrome: A Case Of Nstemi In A Previously Healthy Patient, Hussam Al Hennawi, Muhammad Sabri, David Teng, Maxwell Berman, Botros Shenoda

Abington Jefferson Health Papers

Cytomegalovirus (CMV) infection has been implicated in endothelial dysfunction and atherogenesis, yet its role as a potential trigger for acute coronary syndrome (ACS) remains underrecognized. We present a case of a 32-year-old male with no prior medical history who developed non-ST elevation myocardial infarction (NSTEMI) and was subsequently found to have active CMV infection. The patient had no known history cardiovascular disease, though subsequent testing did reveal additional underlying risk factors. This case highlights the need to consider infectious etiologies, including CMV, as contributors to ACS in young, otherwise apparently healthy individuals. Understanding the interplay between viral infections and atherosclerotic …

Extensive Superficial Dermatomycosis Caused By Cladophialophora Sp., A Deep Mycosis Pathogen: A Case Report, Nikko Vanda Limantara, Agnes Sri Siswati, Flandiana Yogianti

Journal of General - Procedural Dermatology and Venereology Indonesia

Background: Superficial dermatomycosis, predominantly caused by dermatophytes, affects approximately 20–25% of the global population. However, non-dermatophytic fungi, such as Cladophialophora species (sp.), can also cause similar cutaneous infections. Although less common, these organisms are particularly concerning in immunocompromised individuals.

Case Illustration: A 66-year-old immunocompromised male presented with widespread pruritic and erythematous patches, initially misdiagnosed as tinea corporis. Despite receiving standard antifungal therapy, his condition persisted. Further investigation through fungal culture identified Cladophialophora sp., which was resistant to common antifungal agents such as fluconazole, itraconazole, and ketoconazole. However, the fungus was sensitive to terbinafine, which has …

Department of Microbiology and Immunology Faculty Papers

Lyme disease (LD) cases have doubled globally. LD is a tick-borne illness caused by the Borrelia burgdorferi sensu lato (Bb). If untreated, Bb can disseminate to distal organs, causing carditis, arthritis, and meningitis. Currently, no FDA-approved human LD vaccine exists on the market. This study used two approaches to incorporate OspA into the rabies virus (RABV) vaccine vector. We used the RABV-glycoprotein tail (RVG tail) and the Hendra virus (HeV) glycoprotein tail (HVG tail) to incorporate OspA, creating BNSP333-OspA-RVG and BNSP333-OspA-HVG, respectively. Both vaccines produced type-1 biased anti-OspA antibodies, but only BNSP333-OspA-HVG induced neutralizing antibodies and protected against Bb infection. …

Enhancing Preparedness: A Genetic Study Of Sar-Cov-2 And Other Microbial Public Health Threats In Wastewater From A College Town, Christian N. Hutchinson

Master's Theses

Problem

The SARS-CoV-2 (COVID-19) pandemic revealed both the systemic vulnerabilities of our healthcare system as well as the importance of timely, localized data for informing public health responses. Traditional testing approaches were essential but often failed to capture the full extent of viral spread, especially in those with mild or asymptomatic conditions that relied on at home testing. This underreporting hindered effective allocation of resources and made developing effective intervention strategies difficult. We also realized the potential for wastewater surveillance to be applied to tracking antimicrobial resistance gene markers. Taken together, this approach should have important implications for improving public …

Department of Medicine Faculty Papers

BACKGROUND: Facial Necrotizing Fasciitis (FNF) is a rare but aggressive, life-threatening infection involving the face's subcutaneous tissues and underlying musculature. It can rapidly progress to septic shock and multi-organ failure if not promptly recognized and treated. The clinical course, including severe pain, disproportionate tenderness, and systemic signs, is often the most crucial factor in diagnosis. While computed tomography (CT) can aid in identifying early signs such as soft tissue swelling and gas formation, clinical suspicion remains paramount and should not be delayed by reliance on imaging alone. Without early intervention, FNF may lead to devastating outcomes, including disfigurement, blindness, or …

School of Graduate Studies Faculty Publications

Chlamydia trachomatis has a DNA topoisomerase I with a unique C-terminal domain (CTD) homologous to eukaryotic SWIB domains. This study focused on determining the function of the SWIB domain-containing TopA from C. trachomatis (CtTopA). We demonstrated that, despite the lack of sequence similarity at the CTDs between CtTopA and TopA from Escherichia coli (EcTopA), full-length CtTopA removed negative DNA supercoils in vitro and complemented the growth defect of a topA mutant of E. coli. CtTopA is less processive in DNA relaxation than EcTopA in dose-response and time course studies. An antibody generated against the SWIB domain of CtTopA specifically recognized …

Cryptococcus species are major fungal pathogens responsible for life-threatening infections in approximately a million individuals globally each year, with alarmingly high mortality rates. These fungi are distinguished by a distinctive cell wall architecture further reinforced by two virulence-associated layers, melanin and capsule, rendering them insensitive to antifungal agents targeting the cell wall, such as echinocandins. The molecular interplay between these three biomolecular layers remains poorly understood. Here we employ solid-state NMR spectroscopy to examine intact cells of both wild-type and capsule-deficient strains of C. neoformans, along with melanized cells. High-resolution 13C and 1H data revealed five distinct structural forms of …
