Cephalexin is a beta-lactam antibiotic with activity against most gram-positive bacteria. Cephalexin acts by binding to specific penicillin-binding proteins (PBPs) inside the bacterial cell wall. It inhibits the last phase of cell wall synthesis, causing the eventual lysis of the bacterial cell.

This antibiotic is used with XTS Medium (X8454) and PhytoSelect Medium (P6800) for the isolation of: Xanthomonas translucens from barley and wheat seeds during seed testing, Xanthomonas campestris from Brassicas, and other plant pathogens.
