Trichophyton rubrum is a fungus that is the most common cause of athlete's foot , jock itch and ringworm. This fungus was first described by Malmsten in 1845.^[1] The growth rate of Trichophyton colonies is slow to moderately rapid. The texture is waxy, glabrous to cottony. From the front, the color is white to bright yellowish beige or red violet. Reverse is pale, yellowish, brown, or reddish-brown. Although the trichophyton rubrum is the most common of the dermatophytes causing fingernail fungus infections, there are others. Trichophyton mentagrophytes is the second most common source of fungal nail infections from the dermatophyte group.

Athlete's foot properly known as Tinea pedis
Jock itch properly known as Tinea cruris
Fungal Folliculitis of the Scalp properly known as Tinea capitis
Fungal Folliculitis of the Beard properly known as Tinea barbae
Fungal Folliculitis of the Legs properly known as Majocchi granuloma often occurs in females who shave their legs.
Onychomycosis (nail infection)

[edit] 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, devised by the late Gerraldine Kaminski, 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.
