Dermatophytes are fungi that require keratin for growth. These fungi can cause superficial infections of the skin, hair, and nails. Dermatophytes are spread by direct contact from other people (anthropophilic organisms), animals (zoophilic organisms), and soil (geophilic organisms), as well as indirectly from fomites.ransmission of dermatophytes also can occur indirectly from fomites (e.g., upholstery, hairbrushes, hats). Anthropophilic organisms are responsible for most fungal skin infections. Transmission can occur by direct contact or from exposure to desquamated cells.
dermatophytosis. 1. any superficial fungal infection caused by a dermatophyte and involving the stratum corneum of the skin, hair, and nails, including onychomycosis and the various forms of tinea. Called also epidermomycosis and epidermophytosis. 2. tinea pedis.n infection of the hair, skin, or nails caused by any one of the dermatophytes. The lesions are characterized by erythema, small papular vesicles, fissures, and scaling. Common sites of infection are the feet (tinea pedis), nails (onychomycosis), and scalp (tinea capitis).
