Trichophytin

Trichophytin is an extract from the culture of some parasitic fungi of the genus Trichophyton. It is used as an allergen for the diagnosis of trichophytosis, a fungal skin disease caused by dermatophytes.

Trichophytin is obtained by growing Trichophyton fungi on nutrient media and then extracting the active substances. The composition of trichophytin includes proteins and polysaccharides of fungi.

When diagnosing trichophytosis, trichophytin is administered intradermally or applied to the skin. If the body is sensitized to fungal antigens, an allergic reaction develops in the form of hyperemia and infiltration at the injection site. Thus, a positive trichophytin skin test indicates that the patient is infected with dermatophytes.

Trichophytin is widely used for laboratory diagnosis of various forms of trichophytosis, allowing one to quickly identify sensitization to the pathogen and prescribe adequate treatment.

Trichofin is a cultured mold extract that was derived from Trichophyticum minutissimum, and several other varieties have been discovered in Australia. Tr. is suitable for medical and biological purposes. schoenleinii, Tr. mentagrophytes var. quinckeanum. The first type of fungus is the causative agent of dermatophytosis, one of the forms of the second was named after the botanist Erwin Kuhnke, and the third belongs to the group that causes mold corrosion.
