Point mutations in the squalene epoxidase gene of Indian ITS genotype VIII T. mentagrophytes identified after DNA isolation from infected scales

Publication date: Available online 18 September 2019Source: Medical Mycology Case ReportsAuthor(s): Anke Burmester, Uta-Christina Hipler, Reka Hensche, Peter Elsner, Cornelia WiegandAbstractTerbinafine resistant Indian ITS genotype VIII T. mentagrophytes strain was identified by partial sequencing of the squalene epoxidase gene using DNA isolated from infected scales. This method allowed the rapid identification of single point mutations within the squalene epoxidase gene, even before a fungal culture was obtained. Terbinafine resistance was indicated by the amino acid position switch Phe397Leu based on a single point mutation of the codon changing it from TTC to CTC.
