|Description:||Under a magnification of 475X, this photomicrograph depicts some of the ultrastructural pathologic changes that were exhibited by a hair shaft due to a ringworm infection from the dermatophytic fungal organism, Microsporum audouinni. Note the presence of endothrix fungal spores within the hair shaft itself.|
Dermatophytes are fungi that cause skin, hair, and nail infections. Infections caused by these fungi are also sometimes known as "ringworm" or "tinea." Despite the name "ringworm," this infection is not caused by a worm, but by a type of fungus called a dermatophyte. Dermatophytes can live on moist areas of the skin, on environmental surfaces, and on household items such as clothing, towels, and bedding.
