Abstract

The ribosomal region spanning the two internal transcribed spacer (ITS) regions and the 5.8S ribosomal DNA region was sequenced for asexual, anthropophilic dermatophyte species with morphological similarity to Trichophyton rubrum, as well as for members of the three previously delineated, related major clades in the T. mentagrophytes complex. Representative isolates of T. raubitschekii, T. fischeri, and T. kanei were found to have ITS sequences identical to that of T. rubrum. The ITS sequences of T. soudanense and T. megninii differed from that of T. rubrum by only a small number of base pairs. Their continued status as species, however, appears to meet criteria outlined in the population genetics-based cohesion species concept of A. R. Templeton. The ITS sequence of T. tonsurans differed from that of the biologically distinct T. equinum by only 1 bp, while the ITS sequence of the recently described species T. krajdenii had a sequence identical to that of T. mentagrophytes isolates related to the teleomorph Arthroderma vanbreuseghemii.
