| Popis: | The in vitro antifungal activity of terbinafine against 521 clinical isolates of seven species of dermatophytes, including four onychomycosis-causative species, as well as five Scopulariopsis brevicaulis isolates was determined by a modified Clinical and Laboratory Standards Institute microdilution method. Results showed a high antifungal activity of terbinafine against all dermatophyte isolates (geometric minimal inhibitory concentration (MIC)=0.026 microg/mL; concentration inhibiting 50% of mycological growth (MIC50)=0.03 microg/mL; and concentration inhibiting 90% of mycological growth (MIC90)=0.06 microg/mL). The geometric mean MICs against onychomycosis-causative dermatophyte species was lower (0.024 microg/mL) than the global MIC. However, the in vitro activity of terbinafine against S. brevicaulis was considerably lower (geometric mean MIC=1.38 microg/mL) in comparison with dermatophytes. The antifungal activity of itraconazole was lower than that of terbinafine against these fungi. These data confirm the high in vitro antifungal activity of terbinafine against dermatophytes, under standardised conditions. |
