The antifungal resistance in non-fumigatus spp., as well as , poses a major therapeutic challenge which affects the entire healthcare community. Mutation occurrence of 51 gene paralogs is the major cause of azole resistance in spp. To obtain a full map of genomic changes, an accurate scan of the entire length of the genome is necessary. In this study, using whole genome sequencing (WGS) technique, we evaluated the mutation in , , and genes in different clinical isolates of , , , and which responded to minimum inhibitory concentrations of itraconazole above 16 µg mL. We found different nonsynonymous mutations in the , , and gene loci. According to our findings, species isolated from different parts of the world may represent different pattern of resistance mechanisms which may be revealed by WGS.
非烟曲霉属真菌的抗真菌耐药性以及其他方面,构成了一项重大的治疗挑战,影响着整个医疗界。51个基因旁系同源物的突变发生是烟曲霉属真菌对唑类耐药的主要原因。为了获得基因组变化的完整图谱,有必要对烟曲霉基因组的全长进行精确扫描。在本研究中,我们使用全基因组测序(WGS)技术,评估了对伊曲康唑最低抑菌浓度高于16 µg/mL有反应的烟曲霉、黄曲霉、黑曲霉、土曲霉和构巢曲霉不同临床分离株中CYP51、ERG11、TR34/L98H和MDR1基因的突变情况。我们在CYP51、ERG11、TR34/L98H和MDR1基因位点发现了不同的非同义突变。根据我们的研究结果,从世界不同地区分离出的烟曲霉物种可能代表不同的耐药机制模式,这可能通过全基因组测序揭示出来。
