This document provides an overview of the syllabus for a course on medical mycology and virology. The course is divided into 6 units that cover topics such as the taxonomy and characteristics of medically important fungi, fungal infections like candidiasis and aspergillosis, classification of viruses, and techniques for viral diagnosis including PCR and DNA sequencing. The objectives of the course are for students to learn how to perform diagnostic tests to identify fungi. Learning outcomes include understanding the world of microbes like fungi and their adaptive strategies, as well as their economic and pathological importance.

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.
