PYE Agar is a modified version of Sabouraud Dextrose Agar (SDA) by Carmichael and Kraus to detect the presence of dermatophytes, including the causative agents for ringworm, athlete’s foot, and jock itch.
The addition of streptomycin and chloramphenicol inhibit bacterial growth, promoting the detection of pathogenic fungi. Soy peptone and yeast extract provide the nitrogenous sources and vitamins needed for fungal growth, while glucose serves as the energy source. Agar is included as a solidifying agent.
