Use of an Interspecies Chimeric Receptor for Inducible Gene Expression Reveals that Metabolic Flux through the Peptidoglycan Biosynthesis Pathway is an Important Driver of Cephalosporin Resistance in Enterococcus faecalis

Enterococci are dangerous opportunistic pathogens with the potential to cause life-threatening infections due in part to their intrinsic resistance to cephalosporin antibiotics. Elucidating the molecular mechanisms that provide this resistance is critical for the development of strategies to both prevent and treat enterococcal infections.
