FIG. 2.

Southern hybridizations of EcoRI-digested genomic DNAs of strains from four onychomycosis patients (P1 to P4) with T. mentagrophytes infection. A PCR-amplified fragment (∼1,220 bp) of 18S rDNA plus the adjacent ITS region from a T. rubrum strain was used as a probe. Two RFLP types are shown. Lanes marked by a solid line represent strains obtained from the same patient during the course of therapy.
