This photograph featured a Petri dish, which had been used to culture a colony of dermatophytic fungus, Microsporum ferrugineum.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.Created: 1974

This photomicrograph depicts the mycelia, conidiophores, and conidia of the fungus Microsporum gallinae.Created: 1978

This photomicrograph revealed some of the histopathologic characteristics found within a pus specimen, which was prepared using periodic acid-Schiff (PAS), and which had been harvested from a skin lesion in a case of cutaneous coccidioidomycosis. In this particular specimen you’ll note the chlamydospore, or immature spherule of a Coccidioides immitis fungal organism. As the reproductive structure of this, as well as other types of fungi, this spherule is also known as a chlamydoconidium, and contains the organism’s endospores.Created: 1975

This photomicrograph revealed some of the ultrastructural morphology exhibited by Trichophyton rubrum fungal organisms.T. rubrum and T. tonsurans 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 such as 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.Created: 1974

This photograph depicts the frontal view of a Petri dish within which a colony of the African form of the fungus, Trichophyton rubrum, had been cultured. Revealed is the colonial morphology, which in this case is both glaborous, i.e., flat to cottony, and raised and ruffled at its center. Its frontal coloration can range from a white to bright yellowish-beige, as it was here, and even to a red-violet coloration. From the reverse, or from the back, the colonies display a coloration that is a light yellowish to brown, or a reddish brown.Created: 1974
