Adaptation of Aspergillus niger to amphotericin B (AMPH) and two imidazoles (miconazole (MCZ) and ketoconazole (KCZ)) was observed at a single hypha level with a continuous measurement system. It was found that a test hypha adapted to MCZ or KCZ was also adapted to AMPH but that a hypha adapted to AMPH was not adapted either to MCZ or KCZ. These adaptation phenomena to respective agents did not occur after incubation in the medium supplemented with ergosterol. The cross adaptation phenomena were suspected to be due to modification of the synthesis pathway of ergosterol and related derivatives.
