January 2003

(CHROMagar Listeria is available commercially)

This proprietary selective medium differentiates L. monocytogenes and L. ivanovii from other Listeria species based on these species' phospholipases. Differential activity for all Listeria species is due to the addition of a chromogenic substrate. CHROMagar, Paris, France, produces the medium.
