Abstract

Thirty clinical isolates of Candida albicans and 10 other Candida species were tested for susceptibility to 6 substituted dithiocarbamates and one dimercaptosuccinate. Dimethyldithiocarbamate, sodium pyrrolidine dithiocarbamate, and sodium diethyldithiocarbamate showed dose-dependent antifungal activity which was partially reversed by the addition of zinc, copper, or iron sulfate with greatest reversal at 2:1 metal to dithiocarbamate molar ratio. Anaerobiosis also interfered with dithiocarbamate antifungal activity.
