CLED Medium (Bevis Modification) is for the cultivation of coliforms, staphylococci and streptococci, and is not intended for use in the diagnosis of disease or other conditions in humans. Bevis modified Mackey and Sandys original medium by introducing a double indicator to improve the differentiation of lactose and non-lactose fermenting coliforms, staphylococci and streptococci. The swarming of Proteus spp. is inhibited. Neogen’s NCM0220 CLED Medium will grow many of the more demanding streptococci of Lancefield groups A, B, C, G and F. This medium may not grow Pasteurella spp. or halophilic organisms.
