Epidermophyton floccosum
Description and Significance
Epidermophyton floccosum is a parasitic, filamentous fungus that commonly causes tinea pedis (athlete's foot), tinea cruris (jock itch), tinea corporis (ringworm), and onychomycosis (nail infections). Cultures present green, brown, yellow, or khaki colorations with folded centers and a suede like appearance. Other features include long hyphae, flat fringe-like peripherals, and thin-walled macroconidia. Macroconidia are identified as large, multinucleate, asexual spores that are commonly short, wide, and smooth in appearance. In contrast to other dermatophytes, E. floccosum lacks the formation of microconidia and rarely causes hair infection. E. floccosum can be found worldwide but is most common in North America and Asian countries, thriving in tropical and subtropical regions. This microorganism can survive in a variety of ordinary environments such as towels, shoes, clothing, showers, and swimming pools for extended durations of time. As E. floccosum is a common cause of superficial infection of the nails and skin, additional research on dermatophytes is needed to develop higher quality antifungal drugs with fewer, less severe side effects.
