Trichophyton mentagrophytes dermatophytosis in wild fox.

Dermatophytosis caused by a zoophilic varient of Trichophyton mentagrophytes was diagnosed in a litter of eight captured wild red fox (Vulpes fulva). The animals had widespread partial alopecia and scattered crusty foci 2 to 3 cm in diameter on the skin. Treatment with 7 mg/kg/body weight/day of griseofulvin in the feed effectively controlled the infection.
