Molecular identification of Trichophyton interdigitale from patients with dermatophytosis

Abstract

Trichophyton interdigitale is a significant pathogen responsible for dermatophytosis, including tinea unguium & tinea pedis.Fungal genome contains numerous copies of ribosomal DNA (rDNA).(ITS) region can be used to analyze relationships between closely related taxa.The genetic variants of the ribosomal sequences were investigated to assess pattern of biological diversity of three different isolates (assigned S4, S6 and S7) collected in Karbala province.Our results indicated the exact identity of the amplified samples. Sequencing reactions indicated that the identity of samples of S4, S6, and S7 was Trichophyton interdigitale. phylogenetic analyses also confirmed their positions within their corresponding clades accordingly.
