Trichophyton rubrum is a dermatophytic fungus in the phylum Ascomycota. It is an exclusively clonal, [ 2 ] anthropophilic saprotroph that colonizes the upper layers of dead skin, and is the most common cause of athlete's foot , fungal infection of nail, jock itch , and ringworm worldwide. [ 3 ]
Trichophyton is a genus of fungi, which includes the parasitic varieties that cause tinea, including athlete's foot, ringworm, jock itch, and similar infections of the nail, beard, skin and scalp. Trichophyton fungi are molds characterized by the development of both smooth-walled macro- and microconidia .
Dermatophyte (from Greek δέρμα derma "skin" (GEN δέρματος dermatos) and φυτόν phyton "plant") [1] is a common label for a group of fungus of Arthrodermataceae that commonly causes skin disease in animals and humans. [2] Traditionally, these anamorphic (asexual or imperfect fungi) mold genera are: Microsporum, Epidermophyton ...
Zygospore diagram and reproduction. Chlamydospores are asexual spores different from sporangiospores. The primary function of chlamydospores is the persistence of the mycelium and they are released when the mycelium degrades. Chlamydospores have no mechanism for dispersal. In zygomycetes the formation of chlamydospores is usually intercalar.
Athlete's foot is most commonly caused by the molds known as Trichophyton rubrum and T. mentagrophytes, [22] but may also be caused by Epidermophyton floccosum. [23] [24] Most cases of athlete's foot in the general population are caused by T. rubrum; however, the majority of athlete's foot cases in athletes are caused by T. mentagrophytes. [13]
Tests revealed he had a sexually transmitted fungus, called Trichophyton mentagrophytes type VII. It is the first time the fungus has been identified in the U.S. Last year, doctors in France ...
Distal subungual onychomycosis is the most common form of tinea unguium [2] and is usually caused by Trichophyton rubrum, which invades the nail bed and the underside of the nail plate. White superficial onychomycosis (WSO) is caused by fungal invasion of the superficial layers of the nail plate to form "white islands" on the plate. It accounts ...
The most common causative organism is Trichophyton rubrum. [3] The condition is more likely to occur in people who sweat more. [4] Diagnosis is by visualization, microscopy and culture. [4] It may appear similar to dermatitis, psoriasis, keratoderma, hyperkeratosis and allergic contact dermatitis. [5]
