Antimycotic susceptibility testing of mould-fungi with allylamines by disk diffusion.
Susceptibility testing of 17 clinical isolates of mould-fungi, which included Aspergillus spp., (8) Penicillium spp., (2) Paecilomyces spp., (1) Cladosporium spp., (1) Pyrenochaeta romeroi (1) Rhizopus spp., 2. Syncephalastrum spp., (1) and Mortierella spp., (1) were carried out against allylamines-naftifine and terbinafine-(Sandoz Forchungsinstitut) by agar dilution and disk diffusion techniques. Terbinafine was more active than naftifine inhibiting 50 and 90% of the fungi other than zygomycetes at a concentration of 0.5 and 1 microgram/ml whereas the values for naftifine were 2.5 and 10 micrograms/ml. The MIC range for zygomycetes for terbinafine and naftifine were 1-->100 and 100-->100 respectively. The MICs and the sizes of zones of inhibition around the disks correlated well and the degree of correlation was measured by regression analysis. The correlation coefficients for naftifine and terbinafine were-0.9597 and -0.9174 (P < 0.007) respectively.
