Dermatophytes (from the Greek for ‘skin plants’) belong to three groups of fungi that cause skin disease: Microsporum, Epidermophyton and Trichophyton. There are about 40 species in these three genera.

Dermatophytes are classified according to their normal habitat.
- Anthropophilic dermatophytes are restricted to human hosts and produce a mild, chronic inflammation.
- Zoophilic organisms are found primarily in animals and cause marked inflammatory reactions in humans who have contact with infected cats, dogs, cattle, horses, birds, or other animals.
- Geophilic species are usually recovered from the soil but occasionally infect humans and animals. They cause a marked inflammatory reaction, which limits the spread of the infection and may lead to a spontaneous cure but may also leave scars.
Dermatophytes are able to obtain nutrients from keratinized material. The organisms colonize the keratin tissues and inflammation is caused by host response to metabolic by-products.
They are usually restricted to the nonliving layer of the epidermis because of their inability to penetrate viable tissues of their hosts.
