This is a highly magnified photomicrographic view of a number of Ctenomyces serratus conidia.Created: 1971

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 image shows a DTM agar plate culture with colonies of a Trichophyton sp. fungal organism.Created: 1970

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

This was a DTM (Dermatophyte Test Medium) agar plate culture growing the fungus Trichophyton concentricum.Created: 1970

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

Magnified 300X, this photomicrograph revealed the presence of Histoplasma capsulatum var. duboisii fungal organisms in an unidentified tissue sample.What is histoplasmosis?Histoplasmosis is a disease caused by the fungus Histoplasma capsulatum. Its symptoms vary greatly, but the disease primarily affect the lungs. Occasionally, other organs are affected. This form of the disease is called disseminated histoplasmosis, and it can be fatal if untreated.Created: 1972
