Citation: “... In this study, we evaluated DNA sequencing of the D1/D2 region of the large subunit of the 28S ribosomal RNA gene and the internal transcribed spacer (ITS) region using SmartGene ... for the identification of a broad range of commonly encountered filamentous fungi. The [SmartGene] proofreaders were used to upload, align, and edit fragments, and the resultant sequences were interpreted using the quality-controlled [SmartGene] database. The results were compared with reference identifications using conventional phenotypic methods or ITS DNA sequences obtained from GenBank if phenotypic identifications were inconclusive. ...Correct identification was achieved for 100% ... of the isolates when applying both the D1/D2 and ITS targets. In summary, DNA sequencing using [SmartGene] software provides a rapid, accurate, and reliable tool for the identification of filamentous fungi in a clinical laboratory.”
