Lipolytic activity of dermatophytes was tested by the method generally used forCandida lipolytica. Most of the freshly isolated strains ofMicrosporum canis, M. gypseum, Epidermophyton floccosum andTrichophyton mentagrophytes gave positive reactions, whereas, only few strains ofT. schoenleini, T. violaceum, T. megnini, T. rubrum andT. tonsurans yielded such reactions. Among subcultured strains, it was found a decreased lipolytic activity inMicrosporum species and an increased lipolytic activity inEpidermophyton and someTrichophyton species.
