Killing of Aspergillus fumigatus spores and Candida albicans yeast phase by the iron-hydrogen peroxide-iodide cytotoxic system: Comparison with the myeloperoxidase-hydrogen peroxide-halide system

Abstract

A new fungicidal system composed of ferrous ion, H2O2, and iodide is described and compared with the myeloperoxidase-hydrogen peroxide-halide system. Both systems had similar activity against Aspergillus fumigatus spores and the Candida albicans yeast phase, but only the ferrous ion-hydrogen peroxide-iodide system was inhibited by hydroxyl radical scavengers.
