Title A Simple Method To Detect Point Mutations in Aspergillus fumigatus cyp51A Gene Using a Surveyor Nuclease Assay.
Journal Antimicrob Agents Chemother
Abstract One of the main mechanisms of azole resistance of Aspergillus fumigatus is thought to be a reduction in the drug's affinity for the target molecule, Cyp51A, due to its amino acid mutation(s). It is known that the azole resistance pattern is closely related to the mutation site(s) of the molecule. In this study, we tried to develop a simple and rapid detection method for cyp51A mutations using the endonuclease Surveyor nuclease. The Surveyor nuclease assay was verified using several azole-resistant strains of A. fumigatus that possess point mutations in Cyp51A. For validation of the Surveyor nuclease assay, blind tests were conducted using 48 strains of A. fumigatus (17 azole-resistant and 31 azole-susceptible strains). The Surveyor nuclease assay could rapidly detect cyp51A mutations with one primer set. Also, all the tested strains harboring different cyp51A single point mutations could be clearly distinguished from the wild type. The Surveyor nuclease assay is a simple method that can detect cyp51A mutations rapidly.
