SDI Agar (more commonly known as Sabouraud Dextrose Agar or SDA) is a selective solid growth medium widely used in veterinary microbiology for the isolation, cultivation, and identification of pathogenic and non-pathogenic fungi, including yeasts and molds (specifically dermatophytes).

Specs & features.
Developed originally by Raymond Sabouraud in 1892, SDA is primarily designed to cultivate fungi associated with skin, hair, and nail infections in animals (dermatophytosis). It provides a nutrient-rich environment that supports robust fungal growth while intentionally inhibiting competing bacterial flora.
No specifications have been listed.
- Optimized pH: The medium is traditionally adjusted to an acidic pH of approximately 5.6 ± 0.2 at 25°C. This acidic environment naturally restricts the growth of most bacteria, allowing veterinary samples to be screened for fungi without overgrowth.
- High Carbohydrate Content: Contains a high concentration of dextrose (usually 40 g/L), which acts as the primary carbon and energy source for rapid fungal proliferation, pigment production, and spore formation.
- Nitrogen Source: Contains specialized peptones (such as enzymatic digest of casein) to supply essential nitrogen, amino acids, and vitamins.
