New Cefiderocol 30 μg disk

Cefiderocol is a siderophore cephalosporin with a unique mechanism for penetrating efficiently into Gram-negative pathogens.
Cefiderocol binds to free iron and is actively transported into bacterial cells through the outer membrane.
This Trojan horse strategy allows cefiderocol to enter the space in-between the bacterial cell walls and disrupt cell wall synthesis.
In addition, cefiderocol is stable against nearly all beta-lactamases, including both the serine and metallo-carbapenemases.

Disk diffusion breakpoints for cefiderocol are available for  Enterobacteriaceae, P. aeruginosa, A. baumannii and S. maltophilia.
