[Microsporum persicolor, an easily misinterpreted dermatophyt].

Trichophyton persicolor was described by Sabouraud in 1910, and was mistaken by most mycologists for Trichophyton mentagrophytes. Recently the infection in wild rodents was discovered and the independence of this fungus proved by its perfect form (Nannizzia persicolor) which is called at the present time Microsporum persicolor.
