Aim: We sought to provide first insights into the epidemiology and antifungal susceptibility patterns of the aspergilli in Lebanon. Materials & methods: After species identification, antifungal susceptibility was investigated according to EUCAST recommendations. CYP51A gene was sequenced in resistant isolates and its expression level was evaluated by Reverse transcription-quantitative PCR. Results: Among the 73 Aspergillus isolates studied (mostly from ears), the predominant species was Aspergillus niger (54.8%). The overall drug resistance was highest for amphotericin B (38.4%), followed by itraconazole (31.5%), posaconazole (30.1%) and voriconazole (23.3%). In addition, CYP51A gene mutations were not the major cause of azole resistance among these isolates. Conclusion: Our findings indicate the paramount need for an integral One Health strategy and a national reference center for invasive mycoses and antifungals.
