Evaluation Of The Efficacy Of Novel Drugs And Combinations Against Extensively- And Pan-Drug Resistant Acinetobacter Baumannii Isolates, Keertana Jonnalagadda, Rachel Carr, Valerie Carabetta
Evaluation Of The Efficacy Of Novel Drugs And Combinations Against Extensively- And Pan-Drug Resistant Acinetobacter Baumannii Isolates, Keertana Jonnalagadda, Rachel Carr, Valerie Carabetta

Acinetobacter baumannii, a Gram-negative, nosocomial, opportunistic pathogen is commonly infectious in immunocompromised patients. More specifically patients develop healthcare-associated infections (HAI) spanning beyond sepsis, pneumonia, meningitis, and urinary tract infections. Due to its rapid ability to acquire antibiotic resistance, it has raised the necessity to discern a novel therapeutic treatment that can be effectively used against the multidrug resistant (MDR) A. baumannii. Cooper University Hospital (CUH) faced an increased case load of patients that were infected with MDR A. baumannii. The patient isolates obtained from CUH were highly resistant to the 22 standard-of-care antibiotics. With the recent introduction …

Analyzing Pseudomonas Aeruginosa With Bacteriophage Tags Using Photoacoustic Flow Cytometry, Jennifer C. Schinke
Electronic Theses and Dissertations
The number of daily bacterial infections is climbing and the CDC explains that this is due to the antibiotic-resistant threat in the United States. Finding a faster way of bacterial identification is necessary as it currently takes 1-4 days for a medical lab to culture and identify bacteria. Photoacoustic flow cytometry (PAFC) can be used as an alternative method resulting in swift identification within an hour (Edgar, 2019). Pseudomonas aeruginosa, cell line PA01, will be coated in up to a few hundred red dyed phages making it detectible by the photoacoustic flow cytometry system. Bacteriophages (phages) are viruses that …
Characterization Of Antibiotic Susceptibility Profiles Of Extensively- And Pan-Drug Resistant Acinetobacter Baumannii Clinical Isolates, Rachel Carr, Justin Halim, Rebecca Fliorent, Henry Fraimow, Dejan Nikolic, Valerie Carabetta

Rowan-Virtua Research Day
Acinetobacter baumannii is an opportunistic pathogen common in intensive care units (ICUs), particularly among immunocompromised individuals. Nosocomial A. baumannii infections have become increasingly problematic in recent years, as these bacteria rapidly acquire antibiotic resistance, leading to the emergence of multidrug, extensively drug and pan drug-resistant (MDR, XDR, and PDR, respectively) isolates. Recently, Cooper University Hospital (CUH) experienced a large increase in highly drug-resistant A. baumannii infections, which had a mortality rate of 60%. Oftentimes, physicians had to turn to combinations of drugs with no experimental verification or historically shelved antibiotics, such as the polymyxins, in a desperate attempt to save …
Computer-Aided Drug Discovery For Helicobacter Pylori, Nicole Ann Vita
Computer-Aided Drug Discovery For Helicobacter Pylori, Nicole Ann Vita
Theses and Dissertations (ETD)
Helicobacter pylori is a high-priority drug-resistant pathogen and is currently the only bacteria considered to be a class I carcinogen and there is a critical need to identify novel chemical matter to treat H. pylori infections. Hp is responsible for greater than 60% of gastric cancer related deaths and 89% of all gastric cancer morbidities. In a previous study, our lab identified novel Hp thienopyrmidine inhibitors that target respiratory complex I, an essential enzyme in respiration. Respiratory complex I is a large asymmetric multidomain and membrane bound enzyme and due to these innate features, it is not practical for biophysical …
Molecular Mechanisms Of Antimicrobial Resistance In Multi-Drug Resistant Enterococci, Ayesha Khan
Molecular Mechanisms Of Antimicrobial Resistance In Multi-Drug Resistant Enterococci, Ayesha Khan
Dissertations & Theses (Open Access)
Antibiotic resistance is a major global public health threat. Enterococci are recalcitrant, nosocomial pathogens that can be intrinsically resistant to valuable antibiotics, like beta-lactams, or evolve resistance to all existing antimicrobials. The LiaFSR system regulates resistance to cell membrane (CM) stressors like daptomycin (DAP), a front-line drug for multi-drug resistant infections. DAP resistance (DAP-R) in E. faecalis is mediated by CM phospholipid alterations. Emergence of DAP-R often leads to b-lactam resensitization, a phenomenon called the seesaw effect. The molecular mechanism of DAP-R and the seesaw effect are unknown. Here we show that LiaX is a surface exposed protein whose C-terminal …

Combating Antibiotic Resistance In The 21st Century, Kevin Krivanek, Brian Heilbronner, Brendan Rasor, Kelsey Lindsley, Andrew Roecker
Pharmacy and Wellness Review
Antibiotic resistance is one of the most significant challenges facing the medical community today. In response, the Centers for Disease Control and Prevention (CDC) created a list of the greatest antibiotic resistance threats, a number of which are gram-positive bacteria. The cell wall of these organisms has long been a favored target of antibiotic therapies, but the development of numerous resistance mechanisms has led to widespread resistance against nearly all major antibiotic compounds on the market. The medical community is faced with the task of developing better antibiotic compounds that preclude the spread of bacterial resistance and also increasing the …
Infections Not Fought: Antibiotic Resistance In Underserved Communities, Derek Lillestolen
Infections Not Fought: Antibiotic Resistance In Underserved Communities, Derek Lillestolen
Senior Honors Theses
In 1928, the profound effects of penicillin were discovered and antibiotic treatments became extremely popular. Broad-spectrum antibiotics, like tetracyclines, have been since branded as cure-all prescriptions and used profusely in the Western World and abroad. Due to ignorance of specific biochemical mechanisms and the misuse of antibiotics these drugs inadvertently allowed the rise in prevalence of antibiotic resistant strains of certain bacteria as the century progressed. Now, the specific genetic causes and mechanisms of antibiotic resistance are being understood, but the fight against antimicrobial resistance is far from over. In the United States, thousands of fatalities are caused annually by …
