Abstract：Objective To investigate the morphological features and sequences of ribosomal genes in a variant of granular type Trichophyton rubrum isolated from tinea corporis and cruris Methods The morphological features of one T. rubrum strain recovered from a patient with tinea corporis and cruris were observed The ribosomal internal transcribed spacer( ITS),D1/D2 and non-tran-scribed region were determined by PCR Results The phenotype of the isolate produced antlers mycelium,macroconidium had hol-low phenomenon,unilateral budding and it grew at 42℃ The sequences of ITS and D1/D2 were identical to T. rubrum in the Gen-Bank ,but sequences of TRS-1 and TRS-2 in the non-transcribed region were different from the reference strains by 2 and 1 base,re-spectively Conclusion The strain might be a variant of granular type T. rubrum.
