dermatofyt

Dermatophytes are a group of fungi that cause superficial infections of the skin, hair, and nails in humans and animals. These fungi are also known as ringworm fungi. They are characterized by their ability to invade keratinized tissues, which are rich in the protein keratin. The most common genera of dermatophytes are *Trichophyton*, *Microsporum*, and *Epidermophyton*.

Infections caused by dermatophytes are collectively called dermatophytosis or tinea. The specific name of the infection often reflects the location on the body, such as tinea pedis (athlete's foot), tinea cruris (jock itch), tinea capitis (scalp ringworm), and tinea unguium (onychomycosis or nail fungus). Transmission usually occurs through direct contact with an infected person, animal, or contaminated surfaces such as floors, shower stalls, or clothing.

Diagnosis of dermatophytosis typically involves a physical examination, microscopic examination of skin scrapings, and fungal culture. Treatment usually consists of topical or oral antifungal medications, depending on the severity and location of the infection. Good hygiene practices, such as keeping skin clean and dry, and avoiding sharing personal items, can help prevent the spread of these infections.
