Method for detecting trichophytons and associated diseases

The subject matter of the invention is a method for detecting the presence of at least one trichophyton involved in a mycosis of the skin and skin appendages, comprising a step of determining the presence, in a sample of skin or of skin appendage from a human being or an animal that may be infected with a trichophyton, of at least one protease chosen from dipeptidyl peptidase V, subtilisin-like protease 6, subtilisin-like protease 7, leucine aminopeptidase 1 and leucine aminopeptidase 2. The invention also relates specifically to a monoclonal antibody directed against dipeptidyl peptidase V, subtilisin-like protease 6 or leucine aminopeptidase 2 or a fragment of this antibody capable of binding respectively to dipeptidyl peptidase V, subtilisin-like protease 6 or leucine aminopeptidase 2, and a kit containing this antibody.
