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

Viewed from the back, i.e., reverse, this image depicted a Petri dish containing Sabouraud's (SAB) dextrose agar, upon which a Microsporum persicolor fungal colony had been cultured. As seen in this reverse view, the colonial coloration can be yellow, or may even be a red-brown. From the front, as depicted in PHIL 10904 and 10906, the colonies can be white, or depending upon the Microsporum sp., may run the gamut, sporting a yellow, beige or cinnamon color, and display a flat, or glabrous, woolly or powdery texture.Created: 1973

Photographed from the front, this image depicted a Petri dish containing cereal agar, upon which a Microsporum persicolor fungal colony had been cultured. As was the case here, the colonies can be white, or depending upon the Microsporum sp., may run the gamut, sporting a yellow, beige or cinnamon color, and display a flat, or glabrous, woolly or powdery texture. Taxonomically, M. persicolor is a member of the phylum Ascomycota. See PHIL 10905 for a reverse view of this colony, i.e., viewed from behind.Created: 1973

Magnified 500X, this photomicrograph revealed some of the ultrastructural morphology exhibited by the fungal organism, Microsporum persicolor. In this particular image details seen in both a centrally-located macroconidium, and numerous, single-celled microconidia are revealed. Both of these structure types are the asexual spores that originate from the filamentous conidiophore, and are also known as mitospores, for they are born out of the process of mitosis, and are therefore, haploid when they reach maturity. Unlike the single-celled microconidia, the M. persicolor macroconidia are composed of multiple, attached microconidia, separtated by cell walls, and configured in a cigar-shaped chain.Created: 1973

Magnified 500X, this photomicrograph revealed some of the ultrastructural morphology exhibited by the fungal organism, Microsporum persicolor. This particular image highlights details seen in three macroconidia, which are the asexual spores that originate from the filamentous conidiophore. These macroconidia are also known as mitospores, for they are born out of the process of mitosis, and are therefore, haploid when they reach maturity.

Magnified 500X, this photomicrograph revealed some of the ultrastructural morphology exhibited by the fungal organism, Microsporum persicolor. Of particular note are the numerous microconidia configured both in clusters, and as singular units. These microconidia are the asexual spores and originate from the filamentous conidiophore. These conidia are also known as mitospores, for they are born out of the process of mitosis, and are therefore, haploid when they reach maturity.Created: 1973

This photomicrograph depicted a number of Microsporum persicolor fungal microconidia. Under this relatively-high magnification of 1500X, the ultrastructural morphology exhibited by these spores is revealed.Created: 1973

Characterized as echinulate, or spiny, this photomicrograph depicted a number of Microsporum persicolor fungal macroconidia. Under this relatively-high magnification of 1125X, the ultrastructural morphology exhibited by these elongated, roughened spore clusters can be observed.Created: 1973
