Species identification was performed using conventional morphological methods and Matrix assisted laser desorption Ionization time of flight massspectrometry (MALDI-TOF) MS. Azole susceptibility testing was conducted using the gradient test (E-test), the agar plate screening method and broth microdilution for voriconazole (VOR), itraconazole (ITR) and posaconazole (POS). Molecular analysis was performed to detect\n cyp51A<\/jats:italic>\n gene mutations associated with resistance.\n <\/jats:p>\n \n Results.<\/jats:bold>\n Among 125 isolates, species distribution was 44%\n Aspergillus fumigatus<\/jats:italic>\n , 33.6%\n Aspergillus flavus<\/jats:italic>\n , 5%\n Aspergillus terreus<\/jats:italic>\n , 3%\n Aspergillus niger<\/jats:italic>\n and 14%\n Aspergillus<\/jats:italic>\n spp. Using gradient testing,\n A. fumigatus<\/jats:italic>\n showed 1.8% resistance to VOR, 5.45% to ITR and 1.8% to POS, with one isolate resistant to all azoles.\n A. terreus<\/jats:italic>\n showed 16.7% resistance to VOR,\n A. niger<\/jats:italic>\n 25% resistance to ITR and\n Aspergillus<\/jats:italic>\n spp. showed various resistance patterns. The agar plate method detected resistance with 100% susceptibility\/specificity for\n non-fumigatus<\/jats:italic>\n species but 33.3% susceptibility for\n A. fumigatus<\/jats:italic>\n ITR resistance. CypA-L98H mutations were detected in six isolates and CypA-M220 mutations in seven isolates.\n <\/jats:p>\n \n Conclusion.<\/jats:bold>\n This study confirms the presence of azole resistance in clinical\n Aspergillus<\/jats:italic>\n isolates with species-specific variations. The agar plate screening method shows promise for\n non-fumigatus<\/jats:italic>\n species but requires optimization for\n A. fumigatus<\/jats:italic>\n .\n
