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 rubrum was first described by Malmsten [ sv ...
Dermatophytosis. Dermatophytosis, also known as tinea and ringworm, is a fungal infection of the skin [ 2] (a dermatomycosis ), that may affect skin, hair, and nails. [ 1] Typically it results in a red, itchy, scaly, circular rash. [ 1] Hair loss may occur in the area affected. [ 1] Symptoms begin four to fourteen days after exposure. [ 1]
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 ...
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. Macroconidia are mostly borne laterally ...
When onychomycosis is due to a dermatophyte infection, it is termed tinea unguium. Trichophyton rubrum is the most common dermatophyte involved in onychomycosis. Other dermatophytes that may be involved are T. interdigitale, Epidermophyton floccosum, Tricholosporum violaceum, Microsporum gypseum, T. tonsurans, and T. soudanense.
Tinea corporis. This patient presented with ringworm on the arm, or tinea corporis due to Trichophyton mentagrophytes. Tinea corporis is a fungal infection of the body, similar to other forms of tinea. Specifically, it is a type of dermatophytosis (or ringworm) that appears on the arms and legs, especially on glabrous skin; however, it may ...
Dermatophytes are anthropophilic, meaning these parasitic funguses prefer human hosts. 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 .
The disease is primarily caused by dermatophytes in the genera Trichophyton and Microsporum that invade the hair shaft. The clinical presentation is typically single or multiple patches of hair loss, sometimes with a 'black dot' pattern (often with broken-off hairs), that may be accompanied by inflammation, scaling, pustules, and itching.
