Pseudomonas aeruginosa is an opportunistic pathogen of humans and a leading cause of nosocomial pneumonia,urinary tract and post-operative infections. One of the most important virulence determinants of P. aeruginosa is a type III secretion system (T3SS). The T3SS is required for full virulence in animal infection models and functions by translocating effector proteins with anti-phagocytic and cytotoxic properties into host cells. My project involves defining regulatory mechanisms that control T3SS gene expression.
