[Particular features of mycotic carriers (author's transl)].

Although we are all carriers of fungi, an infection is rare. Therefore, the following questions are discussed: Why do these actually saprophytic germs become pathogenic at all? Why have opportunistic fungus infections increased? The diagnosis of a fungus infection due to saprophytic pathogens is difficult, as the demonstration of a fungus does not necessarily imply disease. The case history with relevant predisposing factors is an essential clue to the diagnosis. As a matter of principle, the diagnosis of a systemic mycosis should only be established by exclusion.
