Description:This photograph revealed some of the morphology exhibited by a Trichophyton tonsurans fungal colony. Note the glaborous, or smooth velvety appearance of this colony, and early changes at its center, which in time will lead to its characteristically raised appearance, as well as its yellowish-beige coloration.

T. tonsurans and T. rubrum are two common dermatophytes. These two species are usually transmitted from person to person. Another common dermatophyte is Microsporum canis, which is transmitted from animals, including cats and dogs, to people. Dermatophytes like to live on moist areas of the skin, such as places where there are skin folds. They can also contaminate items in the environment, such as clothing, towels and bedding.
Dermatophytes are types of fungi that cause common skin, hair and nail infections. Infections caused by these fungi are also known by the names “tinea” and “ringworm.” It is important to emphasize that “ringworm” is not caused by a worm, but rather by a type of fungus called a “dermatophyte.” One example of a very common dermatophyte infection is athlete’s foot, which is also called tinea pedis. Another common dermatophyte infection affecting the groin area is jock itch, also known as tinea cruris.
