Genotype analysis of the variable internal repeat region in the rRNA gene of Trichophyton tonsurans isolated from Japanese Judo practitioners

Microbiol Immunol. 2006;50(1):57-60. doi: 10.1111/j.1348-0421.2006.tb03771.x.

Abstract

Tinea capitis due to Trichophyton tonsurans is currently epidemic among Japanese Judo practitioners. T. tonsurans has seven genotypes in a variable internal repeat (VIR) region of the rRNA gene. All 101 isolates obtained from Japanese Judo practitioners had the identical genotype. This suggests that a specific genotype strain occurs throughout Japan.
