Polymyxin acriflavine lithium chloride ceftazidime aesculin mannitol (PALCAM) Listeria Selective Agar is a selective medium. Selectivity is attained mainly by the inhibitory components like lithium chloride, acriflavine, polymyxin and ceftazidime. Two indicator systems confer its diagnostic properties: aesculin and ferric iron and D-mannitol combined with phenol red. This aids in easy differentiation of Listeria spp. from enterococci and staphylococci.
