Sodium chloride tolerance in strains of Epidermophyton floccosum and Epidermophyton stockdaleae.

The ability of strains of genus Epidermophyton to grow at different concentrations of NaCl (ranged from 0 to 10%) was studied. A reduction in the diameter of colonies was observed as the concentration of NaCl increased. A nearly complete absence of macroconidia were shown even at the lowest concentration assayed. The geophilic species E. stockdaleae tolerated higher concentrations of NaCl (> 7%) than E. floccosum (< 3%).
