CLED Agar

This general purpose medium has been recommended for bacteriological urine analysis. Current formulation is a modification of the original one reported by Sandys, that achieves an excellent colony differentiation without inhibitors. This fact, and also the careful selection of nutritive components, makes this medium a substrate able to support growth of most urinary pathogenic bacteria.

Presence of lactose as a fermentable sugar allows classic differentiation and, at the same time, lack of electrolytes suppresses swarming waves on the members of the Proteus species and sometimes growth of Shigella spp. also.
