The urease production test is widely used to identify dermatophytes, and is particularly useful to differentiate Trichophyton interdigitale from the other species of Trichophyton. This test is based on the ability of certain dermatophyte species to produce the enzyme urea, releasing ammonia and increasing the medium's pH, causing its color to change from yellow to dark pink.

The potential use of topical PDT for bacterial and fungal disease is of considerable interest. ALA-PDT has been reported to be effective for inter-digital mycoses although associated with rapid recurrence, and in vitro studies suggest possible efficacy of bioadhesive patch ALA-PDT for Trichophyton interdigitale and Candida albicans (79,80).

Cultures of the lesion revealed fungal hyphae highly suggestive of Trichophyton interdigitale/mentagrophytes. Histopathologic examination of a skin biopsy revealed trichophytic proliferation and a deep folliculitis supporting the diagnosis of MG. Given healthy carrying of dermatophytes on the patient’s guinea pig, a zoophilic infection was suspected. However, DNA sequencing performed on skin biopsy demonstrated the presence of Trichophyton interdigitale, a strictly anthropophilic species.
