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 ...
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]
A 2002 study looking at 445 samples of dermatophytes in patients in Goiânia, Brazil found the most prevalent type to be Trichophyton rubrum (49.4%), followed by Trichophyton mentagrophytes (30.8%), and Microsporum canis (12.6%). [36]
Tinea pedis is caused by fungi such as Epidermophyton floccosum or fungi of the genus Trichophyton including T. rubrum [5] and T. mentagrophytes. [6] These fungi are typically transmitted in moist communal areas where people go barefoot, such as around swimming pools or in showers, and require a warm moist environment like the inside of a shoe ...
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]
The hair perforation test, also known as an in vitro hair perforation test, is a laboratory test used to help distinguish the isolates of dermatophytes, such as Trichophyton mentagrophytes and its variants. [1] The test is performed by placing an organism into a Petri dish containing water, yeast extract, and hair. After incubation for 4 week ...
