Research Focus
The Elfenbein Lab is interested in how Salmonella causes disease and is transmitted between infected individuals. We use a combination of molecular genetics, cell culture, and animal infection models to understand the details underlying Salmonella biology in the gut and in the environment. Our overarching goal is to develop new treatments to ameliorate disease and prevent transmission in order to improve both human and animal health.Recent Publications
