The Effects Of Specialized Pro-Resolving Mediator Lipoxin A4 On Pseudomonas Aeruginosa Biofilms And Interactions With Monocytes, Julianne M. Thornton

Graduate School of Biomedical Sciences Theses and Dissertations

Pseudomonas aeruginosa (P. aeruginosa) is an opportunistic pathogen known as a major cause of hospital-acquired secondary infections, commonly causing chronic respiratory infections in immunocompromised individuals, especially those with cystic fibrosis, and often found in wound infections. P. aeruginosa uses the quorum sensing pathway to readily form protective biofilms, which reduce the efficacy of antibiotics and access by host immune cells to eradicate the pathogen. Specialized pro-resolving mediators (SPMs) are lipids endogenously produced by the host immune response to infection to aid in infection resolution. One SPM, Lipoxin A4 (LxA4), has been shown to be a robust quorum sensing inhibitor.

Characterization Of Bacterial Pathogens Involved In Aerobic Vaginitis: Prevalence, Strain Characterization And Sequelae, Leslie A. Lafferty

Graduate School of Biomedical Sciences Theses and Dissertations

Aerobic vaginitis (AV) is a more recently defined infection that involves aerobic pathogenic bacteria that replace the normal flora of the vaginal tract. It is commonly mistaken for other vaginal infections, such as bacterial vaginosis (BV), because they share many common symptoms. AV leads to complications during pregnancy, such as premature delivery and amnion infection, and is diagnosed by indications that range from vaginal discharge to inflammation. Because this infection is difficult to diagnose differentially from other vaginal infections, it is important to determine what pathogens are involved in AV so that we may have the ability to detect them. …
