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 …

Acinetobacter baumannii is a prevalent nosocomial pathogen where, like many other infectious bacteria, A. baumannii is increasingly considered a multi-drug resistant pathogen. This research study was designed to find a way to affect the persistence of A. baumannii such that it can be applied to a hospital setting to prevent further nosocomial infections. One regulatory mechanism potentially used by A. baumannii to persist on hospital surfaces is through the use of the bacterial second messenger cyclic-di-GMP (c-di-GMP). This nucleotide signal is regulated in response to environmental conditions, and then activates c-di-GMP-binding proteins that induce phenotypic changes. One c-di-GMP-regulated phenotype is …

Over time, “superbugs,” or bacteria that have become resistant to antibiotics, have become a great concern in modern medicine. Viable alternates are currently being looked into as effective and safe ways to prevent or treat infections caused by these superbugs. One such method is through the utilization of the second messenger molecule cyclic-di-GMP (c-di-GMP) that has been shown to regulate phenotypes within other bacteria that may control surface colonization in Acinetobacter baumannii. Through a series of experiments, the active enzymes that create c-di-GMP - diguanylate cyclases - and break down c-di- GMP - phosphodiesterases - have been inactivated in …
