49. Introduction
Sabouraud Dextrose Agar
(SDA)
• Sabouraud Dextrose Agar (SDA) is used for the
isolation, cultivation, and maintenance of non-
pathogenic and pathogenic species
of fungi and yeasts.
• SDA was formulated by Sabouraud in 1892 for
culturing dermatophytes.
• The pH is adjusted to approximately 5.6 in order
to enhance the growth of fungi,
especially dermatophytes, and to slightly inhibit
bacterial growth in clinical specimens.

50. Principle
The SDA media is comprised of enzymatic digest of casein (BHI) and animal tissues which
provide a nutritious source of amino acids and nitrogenous compounds for the growth of fungi
and yeasts.
Dextrose is the fermentable carbohydrate incorporated in high concentration as a carbon and
energy source.
Agar is the solidifying agent.
The addition of antibiotics like Chloramphenicol and/or tetracycline acts as broad-spectrum
antimicrobials to inhibit the growth of a wide range of gram-positive and gram-negative
bacteria.
Cyclohexamide is added to further inhibit the growth of gram-negative bacteria.

51. • Ch
Chloramphenicol – Suppress growth of
contaminating bacteria
Cycloheximide – Suppress growth of
contaminating fungi.
Brain heart infusion (BHI) with blood and
antibiotics – for primary isolation of fungi.
