Microsporum spp

Microsporum spp are dermatophyte fungi that cause cutaneous infections of the nails, hair, and skin, known as dermatophytosis. They are ascomycetous molds producing macroconidial spores which are distinct for these group of dermatophyte, distinguishing them from other dermatophytes such as Trichophyton and Epidermophyton.

Common infections caused by dermatophytes include tinea pedis (athlete’s foot), tinea crusis, tinea corporis, and onychomycosis. It is the third most common cause of Tinea … Read more Epidermophyton floccosum

Blastomyces dermatitidis
