title: [Dermatoses provoked by opportunistic fungi].
abstract: In my exposé I confined myself to the moulds. Generally speaking, there are two groups of fungi. One group that often provokes diseases in otherwise normal subjects (fungi of parasitic-pathogenic character) and a second group that causes diseases in cases of lowered immunobiological resistance (fungi of saprophytic-opportunistic character). Though the biological conditions of the host are important, they are by no means the only prerequisites for the development of a mycosis. Just as important are the enzymatic qualities of the fungus. Ubiquitous moulds can become opportunists and provoke dermatoses under two conditions: (1) The fungus must possess keratolytic capabilities (2) its penetration and growth must be preceded by a lesion due to trauma, or bacterial or viral infection.
