Exogenous Polyunsaturated Fatty Acid (Pufa) Scavenging Affects Phospholipid Profiles And Virulence Phenotypes In Vibrio Cholerae And Vibrio Parahaemolyticus, Anna Moravec
Honors Theses
AIM: This research had two primary objectives. First, this study sought to determine whether or not exposing Vibrio cholerae and Vibrio parahaemolyticus to polyunsaturated fatty acids (PUFAs) would lead to changes in their respective phospholipid profiles. Secondly, if membrane remodeling occurred, this study sought to determine the impact of membrane modifications on bacterial fitness by evaluating their effect on membrane permeability, biofilm formation, and response to stresses. METHODS: The Bligh and Dyer method was used to extract bacterial lipids, which were subsequently analyzed via thin-layer chromatography (TLC). The effect of fatty acids on bacterial fitness was assessed using stress, biofilm, …
