Sabouraud Dextrose Agar (SDA) is a specialized growth medium primarily used for the cultivation of fungi, including yeasts and molds. Developed by Raymond Sabouraud in the late 19th century, it is composed of peptones, dextrose, and agar. The high sugar content and acidic pH of SDA support the growth of fungi while inhibiting bacterial growth, making it ideal for isolating pathogenic fungi from clinical specimens.
