Activity of deferasirox in Mucorales: influences of species and exogenous iron.
Differences in deferasirox susceptibility among members of the order Mucorales are unknown. Here we show that Cunninghamella bertholletiae (four isolates) and Mucor species (five isolates) display higher deferasirox MICs and minimal fungicidal concentrations compared to Rhizopus species (six isolates). Exogenous iron further attenuated the deferasirox susceptibility of Mucorales isolates with low MICs. Vital staining revealed damage to subapical compartments in susceptible strains.
