In vitro and in vivo antifungal activity of the combination methylpartricin-5-fluorocytosine.

In vitro studies on the antifungal activity exerted by the combinations SPA-S-222 (a hydrosoluble derivative of the polyene antibiotic methylpartricin) and 5-fluorocytosine evidence a favourable interaction against the formation of germ-tube in Candida albicans; against Cryptococcus neoformans and 5FC induced-resistant strains of Candida albicans. In the experimental infections with Candida albicans and Cryptococcus neoformans a significantly favourable interaction was exerted by polyene-5FC combinations.
