Sabouraud Cycloheximide Dextrose Agar is a selective medium that can be used for cultivating yeasts, molds and aciduric microorganisms. It is also used for cultivating pathogenic fungi, particularly those associated with skin infections. This medium is at the same time used for determining the microbial and fungal content of cosmetics and for the mycological evaluation of food. Dextrose is the fermentable carbohydrate that provides carbon and energy. Peptone mixture is source of nitrogen, vitamins and amino acids. Bacteriological agar is the solidifying agent. The high dextrose concentration and acidic pH make this medium selective for fungi. This medium is a modification of the Dextrose Agar (Cat. 4513) described by Sabouraud, with the addition of cycloheximide. Cycloheximide is an antibiotic which inhibits saprophytic fungi but allows the growth of pathogenic fungi: Cryptococcus neoformans, Aspergillus fumigatus and some species of Candida (albicans, krusei).
