Trichophyton Rubrum - Identification

Identification

Positive, selective diagnosis of T. rubrum is difficult as many members of the genus react similarly with test reagents. The Mycology Unit at the Adelaide Women's and Children's Hospital uses a dermatophyte identification scheme comprising 6 different media to help identify and differentiate the various species and strains of Trichophyton. The media in this scheme are Littman Oxgall agar, Lactritmel agar, Sabouraud's agar with 5% NaCl, 1% Peptone agar, Trichophyton agar No. 1, and hydrolysis of urea.
