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 .
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]

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 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]
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 ...
