[Intrafamilial transmission of Trichophyton verrucosum to a newborn].

At the age of 4 weeks a suckling developed discoid erythema with scales and a few pustules at the face. Previously, his father having contact with cattle as a farmer had fallen ill from tinea barbae. In both cases Trichophyton verrucosum could be detected by culture. Dermatophytosis in sucklings has recently more often been reported about in the literature. This, however, does not apply to Tr. verrucosum infections.
