Comparative amplification profiles of A. fumigatus wild type and environmental or clinical azole-resistant isolates with or without TR46 double or triple 46 bp promoter repeats in cyp51A gene by a newly developed LAMP primer sets. The dotted curve shows the amplification by control strain (IFM 63432). (A-i) DNA amplification profiles using 30 strains of A. fumigatus wild type. DNA amplification was not confirmed in all wild-type strains tested (30 strains). Among 30 wild-type strains, IFM 62918 strain was used as a negative control strain (no amplification). (A-ii) DNA amplification was confirmed by five TR462 strains (IFM63432, BE1-2, BE1-4, BE3-5, BE3-6), which have double 46 bp promoter repeats. (A-iii) DNA amplification was confirmed by three TR463 strains (BE1-1, W1-4, W2-12-1), which have triple 46 bp promoter repeats. (B-i) DNA amplification was not confirmed by two TR342 strains (IFM64460, IFM64733), which have duplicate 34 bp promoter repeats with one mutation in the one coding region (L98H). The dotted line shows amplification by the control strain. (B-ii) DNA amplification was not confirmed by one TR342 strain (3-1-B), which has duplicate 34 bp promoter repeats with multi-mutations in the four coding regions (L98H/T289A/I364V/G448S). The dotted line shows amplification by the control strain.
