69939-7Trichophyton rubrum DNA [Presence] in Nail by NAA with probe detectionActive

Term Description

This term was created for, but not limited to, Staten's Serum Institute Dermatophyte-Trichophyton rubrum test kit, which is is an in vitro diagnostic detection of dermatophytes in general (pan-dermatophytes) (see LOINC 70027-8) as well as Trichophyton rubrum. The primer pairs are directed towards genes encoding chitin synthase 1 (chs1, 366bp amplicaon size) for detection of dermatophytes and ITS2 (internal transcribed spacer, 203bp amplicon size) for detection of T. rubrum.

Part Descriptions

LP17225-1   Trichophyton rubrum
Trichophyton rubrum is a fungus that is the most common cause of athlete's foot , jock itch and ringworm. The growth rate of Trichophyton colonies is slow to moderately rapid. The texture is waxy, glabrous to cottony. From the front, the color is white to bright yellowish beige or red violet. Reverse is pale, yellowish, brown, or reddish-brown. Although the trichophyton rubrum is the most common of the dermatophytes causing fingernail fungus infections, there are others. Trichophyton mentagrophytes is the second most common source of fungal nail infections from the dermatophyte group.

LP17225-1   Trichophyton rubrum
Trichophyton fungi inhabit the soil, humans and animals, different species preferring different environments. Most common are Trichophyton mentagrophytes, Trichophyton rubrum, Trichophyton schoenleinii, Trichophyton tonsurans, Trichophyton verrucosum, and Trichophyton violaceum. Some species are cosmopolitan. Others have a restricted geographic distribution. Trichophyton concentricum, for example, is endemic on Pacific Islands, Southeast Asia, and Central America. Trichophyton is one of the leading causes of hair, skin, and nail infections in humans.

Fungal infections of the skin, nails or hair are extremely common and often caused by dermatophyte fungi of the genus Trichophyton. Trichophyton spp. classically induce delayed-type, or cell-mediated, hypersensitivity, but a unique feature of Trichophyton allergens is the ability of the same antigen to elicit immediate-type hypersensitivity reactions as well Copyright Copyright © 2006 Phadia AB.
