Molecular identification of<i>Trichophyton rubrum</i>isolate from a dog by chitin synthase 1 (<i>CHS1</i>) gene analysis

Abstract

A nonsporulating isolate from a dog with dermatophytosis was identified as Trichophyton rubrum by molecular analysis. The nucleotide sequence analysis of the chitin synthase 1 (CHS1) gene from the isolate indicated more than 99% sequence similarity with other human and canine isolates of T rubrum. The molecular typing suggested that isolates of T. rubrum from human and canine sources were genetically identical.
