Non-wild-type A. fumigatus isolates were selected for further detection of cyp51A mutations. Of the selected isolates, the full sequences of cyp51A gene along with the promotor regions were amplified with previously described PCR primers and conditions and the amplified products were sequenced with Applied Biosystems sequencer (ABI 3130, Foster City CA, USA). The DNA sequences of the non-wild-type A. fumigatus strains were compared with the wild-type susceptible A. fumigatus reference strain (GenBank AF338659).
