By stripping Salmonella of its molecular “effectors,” this research identifies interferon gamma as a key immune barrier preventing infection. A small set of SPV genes enables the bacterium to overcome this defense. Understanding these mechanisms reveals new targets for therapies against Salmonella, a major global health threat.

This research investigates how the body’s natural use of copper—through nutritional immunity—can be leveraged to combat antibiotic-resistant E. coli infections in urinary tract infections. By understanding bacterial susceptibility to copper, this work aims to identify novel, host-inspired strategies for treating UTIs.
