Kan kültürlerinden izole edilen Candida türlerinin antifungal duyarlılıklarının Sensititre YeastOne mikrodilüsyon yöntemiyle araştırılması

Year 2020, Volume: 77 Issue: 3, 281 - 288, 01.09.2020

Abstract

Amaç: Candida türlerinin neden olduğu invaziv fungal enfeksiyonlar önemli ölçüde artmıştır. Bu nedenle türlerin hızlı ve doğru tanımlanması ve duyarlılık testleri, özellikle fırsatçı enfeksiyonları içeren vakalarda oldukça önemlidir. Mikrodilüsyon esasına dayanan Sensititre YeastOne yöntemi, antifungal duyarlılık testi için Klinik ve Laboratuvar Standartları Enstitüsü referans yöntemine uygun bir alternatiftir. Sensititre YeastOne liyofilize halde antifungal içeren kuyucuklara sahip olup Candida izolatlarının Minimal İnhibitör Konsantrasyonu MİK değerlerinin belirlenmesi için geliştirilen bir yöntemdir. Çalışmamızda kan kültürlerinden izole edilmiş Candida izolatlarının Sensititre YeastOne kolorimetrik sistem kullanılarak antifungal ilaç duyarlılığının belirlenmesi amaçlanmıştır.Yöntem: Çalışmaya Atatürk Üniversitesi Tıp Fakültesi Tıbbi Mikrobiyoloji Laboratuvarı’nda her biri farklı hastalara ait kan kültürlerinden izole edilen 50 Candida izolatı 16 Candida albicans, 14 Candida tropicalis, 10 Candida glabrata, 8 Candida parapsilosis, 2 Candida kefyr ve iki adet kalite kontrol suşu Candida krusei ATCC 6258, Candida parapsilosis ATCC 22019 dahil edilmiştir. Türlerin antifungal duyarlılıkları, kolorimetrik bir sistem olan Sensititre YeastOne Trek Diagnostic Systems, ABD mikrodilüsyon yöntemi ile araştırılmıştır. Bulgular: Çalışma sonunda Candida izolatlarının tamamında MİK aralıkları; amfoterisin B için 0,12-2 μg/ml, flukonazol için 0,12-256 μg/ml, vorikonazol için 0,008-8 μg/ml, kaspofungin için 0,015-0,5 μg/ml, anidulafungin için 0,015-2 μg/ml, mikafungin için 0,0082 μg/ml, flusitozin için 0,006-8 μg/ml, posakonazol için 0,008-8 μg/ml, itrakonazol için 0,015-16 μg/ml olarak belirlenmiştir. Sonuç: Elde edilen düşük MİK değerleri göz önüne alındığında anidulafungin, mikafungin, kaspofungin, flusitozin, posakonazol, vorikonazol, itrakonazol ve amfoterisin B’nin Candida izolatlarına karşı etkin olabileceği ve flukonazole dirençli suşlarla oluşan enfeksiyonların tedavisinde alternatif ilaç olarak kullanılabilecekleri sonucuna varılmıştır

An investigation of antifungal susceptibilities of the Candida species isolates from blood cultures using the Sensititre YeastOne microdilution method

Year 2020, Volume: 77 Issue: 3, 281 - 288, 01.09.2020

Abstract

Objective: Invasive fungal infections caused by Candida species have increased significantly. Therefore, rapid and correct identification to the species level and susceptibility testing have become important, especially in cases involving invasive infections. The Sensititre YeastOne method, based on the microdilution method, is an alternative to the Clinical and Laboratory Standards Institute CLSI reference method for antifungal susceptibility testing. Sensititre YeastOne is a method for determining the Minimal Inhibitory Concentration MIC values of Candida isolates with wells containing lyophilized antifungals. In our study, the aim was to determine the antifungal drug sensitivity of Candida isolates from blood cultures by using a Sensititre YeastOne colorimetric system.Methods: Fifty candida isolates, each isolated from blood cultures of different patients in the Medical Microbiology Laboratory of Atatürk University Faculty of Medicine, were included in the study 16 Candida albicans, 14 Candida tropicalis, 8 Candida parapsilosis, 10 Candida glabrata, 2 Candida kefyr and two quality control strain Candida krusei ATCC 6258, Candida parapsilosis ATCC 22019 were included in the study. The antifungal susceptibilities of the species were tested by the microdilution method using a colorimetric method, Sensititre YeastOne Trek Diagnostic Systems, USA . Results: For all Candida species, MIC ranges were as follows: 0.12-2 μg/ml for amphotericin B; 0.12-256 μg/ml for fluconazole; 0.008-8 μg/ml for voriconazole; 0.015-0.5 μg/ml for caspofungin; 0.015-2 μg/ml for anidulafungin; 0.008-2 μg/ml for micafungin; 0.006-8 μg/ml flucytosine; 0.008-8 μg/ml for posaconazole and 0.015-16 μg/ml for itraconazole. Conclusion: Considering the low MIC values obtained, it was concluded that anidulafungin, micafungin, caspofungin, flucytosine, posaconazole, voriconazole, itraconazole and amphotericin B may be effective against Candida species and may be used as alternative drugs for the treatment of infections caused by fluconazole-resistant species.
