Single strains of Trichophyton rubrum in cases of tinea pedis

J Med Microbiol. 2005 Aug;54(Pt 8):725-726. doi: 10.1099/jmm.0.45903-0.


Multiple colonies of Trichophyton rubrum were isolated from single skin specimens from 10 patients with tinea pedis and were typed using a PCR-based analysis of repeats in the rRNA intergenic spacer. In each case only a single strain type of T. rubrum was isolated, suggesting a monotypic aetiology of tinea pedis. This is in contrast to the multiple strains previously shown to be involved in many cases of onychomycosis.
