title: Multicenter evaluation of Neo-Sensitabs, a standardized diffusion method for yeast susceptibility testing.
abstract: The agar diffusion method Neo-Sensitabs for sensitivity testing, was evaluated with 33 reference strains by fourteen laboratories. Tablets with 5-fluorocytosine, amphotericin B, nystatin, fluconazole, itraconazole, ketoconazole and tioconazole were used on Shadomy modified medium. These tests classify each strain as susceptible, intermediate or resistant to all tested antifungals by measuring the inhibition zone diameters. Intra and interlaboratory reproducibility was studied. Neo-Sensitabs sensitivity for fungi was easy to perform and reliable method with a reproducibility of 97.1% and superior to other commercialized methods, being specially interesting for antifungal susceptibility in vitro testing of triazole derivatives fluconazole and itraconazole.
