Pseudomonas aeruginosa drug efflux pump and metabolism

Project Description

Pseudomonas aeruginosa is a Gram-negative opportunistic pathogen that can infect almost any site of the body and is highly resistant to antibiotics. The organism is most infamous for chronic pneumonia of patients afflicted with cystic fibrosis and the third leading cause of hospital-acquired infections. The microorganism is quite adaptable to several different environmental conditions. We have been studying its ability to adapt to the lung environment by dissecting a signal transduction system, called AlgZR, that controls many different phenotypes that are required for virulence. Recently, we have discovered that the organism's ability to efflux drugs is linked to fatty acid metabolism through a membrane-bound drug efflux pump. We will be testing the hypothesis that growth on fatty acids induces P. aeruginosa resistance to fluoroquinolones through the control of the MexEF oprN drug efflux pump.
