Investigating The Synthesis And Antibacterial Activity Of A Main-Chain Cationic Polymer, Emily Smith

Honors Theses

Antibiotic resistance is a growing threat to public health. Due to the overuse of antibiotics in agriculture, the overprescription of antibiotics, and the misuse of antibiotics by patients, antibiotic resistance is spreading at an alarming rate. As antibiotic resistance spreads, the antibiotics we depend on to treat common infections become ineffective. Therefore, it is imperative to develop novel treatments for infections that do not increase the prevalence of antibiotic resistance. One treatment being explored is the use of synthetic polymers with antibacterial properties. Synthetic polymers are advantageous because they can be synthesized from widely available precursors and their structure is …

Structural Transformation Of A Hydrogel-Forming Cell Division Protein Zapb Of Multidrug Resistant Klebsiella Pneumoniae With Small Molecules, Ayesha Khan, M. Iqbal Choudhary, Sumaira Javaid, Humaira Zafar, Innokentiy Maslennikov, Atia-Tul Wahab

Pharmacy Faculty Articles and Research

Septal ring assembly protein ZapB (EMR18431.1) is involved in Z-ring formation, and nucleoid segregation during the bacterial cell division . It promotes cell division in the initial stages of the cell cycle through direct interaction with FtsZ, thus stimulating Z-ring assembly. The ZapB inhibition can make bacterial cell susceptible to primary antibiotics, and therefore considered as an important approach for adjuvent therapy against MDR bacterial infections. Hence in the current study, ZapB protein of multidrug resistant Klebsiella pneumoniae was cloned, and expressed in E. coli system. To understand its role, and to assess the mechanism of ZapB activation, the characteristic …

Antibiotics And You: A Comprehensive Guide, Brady Haas

Senior Theses

Antibiotic resistance is a rapidly emerging issue within public health. As resistance grows, the effectiveness of traditional antibiotic therapies diminishes while risk of treatment grows. Alongside novel therapies, public knowledge is a strong combatant of the resistance-related risks of antibiotic usage. Through a comprehensive review of current literature, this work serves as an accessible guide to the mechanisms of antibiotics, bacterial resistance, and the challenges related to current antibiotic usage. Additionally, the ability of current policy and emerging novel treatments, such as nanoparticles and bacteriophage therapy, to fight antibiotic resistance is evaluated. This analysis highlights the importance of improving public …

Hyperglycemia And Mycoplasma Pneumoniae Cards Toxin Impacts On Lung Epithelial And Fibroblast Injury And Recovery, Alejandra Y. Delgado, Naila Villagomez, Shuri Magdalene

Posters - 2026

Mycoplasma pneumoniae CARDS toxin induces cytotoxicity and inflammation in lung epithelial cells²·¹⁰·¹¹, while hyperglycemia independently elevates ROS and disrupts fibroblast repair¹·⁵·⁸, contributing to the heightened respiratory infection severity seen in diabetic patients¹. However, the interaction between hyperglycemic conditions and CARDS toxin-induced lung injury remains unexplored.

This study investigates how increasing high-glucose (HG) pre-conditioning modifies CARDS toxin-induced injury and recovery in A549⁶ and IMR-90⁷ cells compared to normal glucose (NG ≈ 5mM) controls. We hypothesized that increasing glucose pre-conditioning concentrations would produce a dose-dependent increase in CARDS toxin-induced oxidative stress¹² and inflammatory cytokine production¹⁵ in IMR-90 and A549 compared with normal …

Aircraft Wastewater Surveillance As A Tool For Monitoring Disease In The Pacific, Carla J. Eaton, Joanne R. Chapman, Brent J. Gilpin

Pacific Journal of Health

Wastewater surveillance is a powerful tool for monitoring infectious diseases within a population. However, as most wastewater surveillance relies on interconnected wastewater networks to provide samples representative of the population, many Pacific Islands have been excluded from benefiting from this tool due to their lack of reticulated sewerage systems. Many diseases of concern for the Pacific are detectable in wastewater even though individuals may be asymptomatic. We investigated whether analysis of wastewater from aircraft arriving in New Zealand from Pacific Island nations could be used as a proxy for in-country surveillance. Flights from the Pacific arrive in Auckland daily, with …

Ninety-day medical complications, including readmission, emergency department utilization, venous thromboembolism, pneumonia, urinary tract infection, stroke, sepsis, respiratory failure, …

Investigating Corollaries Between Streptococcus Gallolyticus Subsp. Gallolyticus Virulence And Colorectal Cancer, Tyler G. Myers

Pursuit - The Journal of Undergraduate Research at The University of Tennessee

Streptococcus gallolyticus subsp. gallolyticus (Sgg) is a gram-positive, non-beta-hemolytic bacterium that belongs to the Lancefield group D of streptococcal pathogens. For the past several decades, associations between Sgg bacteremia and colorectal cancer (CRC) have been apparent, with gastroenterologists routinely recommending colonoscopies for positive cases of Sgg in either blood or stool samples. However, current research has not wholly established whether Sgg acts as a causative agent of CRC or if pre-existing cancers make the lumen of the colon more hospitable to its colonization. Regardless, Sgg has been implicated in the modulation of host inflammatory pathways and subsequent remodeling …

Selectivity Modulation Of Small Cationic Membrane-Active Cyclic Peptides With Broad-Spectrum Activity Against Bacteria And Fungi, Sandeep Lohan, Rakesh Kumar Tiwari, Innokentiy Maslennikov, Kaustav Das Gupta, Shakti Singh, Keykavous Parang

Pharmacy Faculty Articles and Research

To investigate how ring size and backbone flexibility influence antimicrobial potency and cytotoxicity, we synthesized a series of macrocyclic peptides of lead peptide p1 (c[Arg-Arg-arg-arg-dip-Trp-dip]) by incorporating Gly, 2-aminoethoxyacetic acid (EAA), or 2,4-diaminobutyric acid (Dab). Two optimized peptides, 6b and 10b, retained broad-spectrum activity against drug-resistant Gram-positive (MIC, 1.5–6.2 μg/mL) and Gram-negative bacteria (MIC, 4–25 μg/mL), as well as pathogenic fungi, while exhibiting enhanced selectivity for microbial cells. Their therapeutic indices (TI ∼407 and ∼394, respectively) were ∼2-fold higher than p1, indicating improved safety. Both peptides remained effective against Gram-negative pathogens beyond the reach of daptomycin, were rapidly bactericidal, and …

Pleural fluid culture grew Cupriavidus pauculus, a rare environmental gram-negative bacillus, alongside Burkholderia cepacia and Candida parapsilosis, indicating polymicrobial infection which was most likely predisposed by patient's immunosuppressed state from RA and prolonged steroid use. Treatment consisted of trimethoprim/sulfamethoxazole, meropenem, fluconazole, and cardiopulmonary support, and culminated in …

Epidemiology Of Healthcare-Associated Ventriculitis And Meningitis (Hcavm) And Community-Acquired Meningitis/Encephalitis And Evaluation Of An Off-Label Pcr Panel For Hcavm Diagnosis, Jaime Nassur, Katarina Schnell, Christine Dolon, Laura Walters, Devin Weber, Matthew Pettengill

Department of Medicine Faculty Papers

Healthcare-associated ventriculitis and meningitis (HCAVM) is associated with high morbidity and mortality, but rapid diagnostic tests intended to cover microorganisms that typically cause HCAVM are not commercially available. We sought to evaluate the etiology of HCAVM compared to community-acquired meningitis/encephalitis (CAME) at our healthcare system, and to study the utility of repurposing a multiplex molecular panel intended for positive blood cultures for HCAVM cases. Our epidemiologic review demonstrated that HCAVM cases were primarily caused by bacteria and fungi also associated with bloodstream infections, in contrast with CAME cases, which were primarily caused by herpesviruses and Cryptococcus. Eighty-two cerebrospinal fluid …

Disguised And Dangerous: A Case Of Cervicofacial Actinomycosis Presenting With Hemoptysis, Tharun Shyam, Shamanth M Reddy, Saumya Nanda, Yan Naing Tun, Rohan Pinto, Navjot Somal, Ravi Karan Patti

Journal of Community Hospital Internal Medicine Perspectives

Actinomycosis is a rare, chronic, suppurative bacterial infection caused by Actinomyces spp with an incidence of 0.3 cases per million people annually. The cervicofacial area is the most common site of infection and accounts for approximately 50 percent of all cases. Most cases of cervicofacial actinomycosis are odontogenic in origin.

Hemoptysis in the setting of actinomycosis commonly occurs from pulmonary involvement. Hemoptysis secondary to isolated cervicofacial actinomycosis has seldom been documented in literature. We hereby present a case of cervicofacial actinomycosis presenting with hemoptysis likely secondary to an oro-cervical fistula. We aim to highlight the challenges in diagnosis of this …
