First fluconazole-resistant Candida auris isolated from fungal otitis in Iran

Background and Purpose: Candida auris, as a new characterized pathogenic yeast,has attracted remarkable attention in the recent decade due to its rapid global emergence and multidrug resistance traits. This unique species is able to cause nosocomial outbreaks and tolerate adverse conditions; however, it has been mostly misidentified by conventional methods. Case report: This report aimed to describe the first fluconazole-resistant case of C.auris otitis in an immunocompetent patient in Iran. The isolate showed minimum inhibitory concentration of ≥ 32 μg/ml for fluconazole; however, the patient was treated with topical clotrimazole and miconazole with no recurrence. Conclusion: This was the second strain of C. auris isolated from otitis in Iran which was fluconazole-resistant, unlike the first Iranian isolate.
