Chrysonilia sitophila: Growth on Different Culture Media and Sensitivity to Antifungals

The species Chrysonilia sitophila has a cosmopolitan spread, living on dead or rotting plants, but it is also isolated from home and commercial spaces insulation. The aim of our study was to determining a growth pattern and assessing the susceptibility to different antifungals. The strain was isolated from the water of a trout breeding pool where high mortality due to Saprolegnia infection and various Gram negative and Gram positive bacteria occurred. On all used culture media (except for MacConkey), rapid growth is observed (tendency to spread over the entire surface of the plate in 36-48 hours). The isolated strain has been shown to be sensitive to ketoconazole, econazole, and miconazole; less sensitive to amphotericin B, but resistant to metronidazole, nystatin, griseofulvin and flucytosine. Chrysonilia sitophila can be grown easily, so it can also establish an antifungal sensitivity profile. Additional efforts should be made to study the pattern of susceptibility to different antifungals.
