In this study, we have investigated in vitro the resistance frequency and development of resistance to terbinafine of Trichophyton rubrum. Results demonstrated that naturally occurring mutants are rare and that T. rubrum appears to have little capacity to develop resistance to terbinafine even after prolonged exposure.
