Abstract

Aim: In this study was aimed to determine the antifungal susceptibility and the distribution of Candida species isolated from different clinical samples of patients admitted to the Bozok University Research and Application Hospital.Material and Methods: In our study, forty-two Candida species isolated from clinical samples between the October 2014 and January 2016 dates were evaluated retrospectively. For the identification of isolates; germ tube test and commercial VITEK 2 Compact® (Biomerieux, France) was used the yeast identification system. Antifungal susceptibility of isolates was detected by using VITEK 2 AST YS02 disposable test cards containing fluconazole, voriconazole, caspofungin, micafungin, amphotericin-B and flucytosine for use with VITEK® 2 instruments. Results: A total of 42 Candida species were isolated from various clinical specimens. C. albicans was the most frequently isolated species with 66.7% while non-albicans species were detected in 33.3%. Other Candida species were as follows; C. glabrata (11.9%), C.kefy is (7.1%), C.tropicalis (4.8%), C.famata (2.4%), C.kruse (2.4%), C.lusitania (2.4%) and C.spherica (2.4%), respectively.In all isolates, the rates of antifungal resistance were found 14% for fluconazole, 6% for voriconazole, 5% for amphotericin-B, 6% for caspofungin and 3% for micofungin. Fluconazole resistance rate was found as 11% in C. albicans isolates. In the isolates of C.kefyr, C.lusitania and C.tropicalis was not saw resistance to existing antifungals. Antifungal resistance ratio of C. glabrata was higher than the other Candida species. Conclusion: In our study the isolates of C. glabrata following the most frequently isolated C. albicans were found to have higher antifungal resistance than the other Candida species. In recent years, due to the increase of non-albicans species and antifungal resistance rates, it has been thought that identification of Candida species and antifungal susceptibility tests should be done.

Özet

Amaç: Bu çalışmada Bozok Üniversitesi Araştırma ve Uygulama Hastanesi’ne başvuran hastalara ait çeşitli klinik örneklerden izole edilen Candidaların tür dağılımları ve antifungal duyarlılık oranlarının belirlenmesi amaçlanmıştır. Gereç ve Yöntemler: Ekim 2014-Ocak 2016 tarihleri arasında Candida türleri izole edilen 42 adet klinik örnek retrospektif olarak değerlendirildi. İzolatların tanımlanmasında germ tüp testi ile ticari VITEK 2 Compact® (Biomerieux, France) maya identifikasyon sistemi kullanıldı. İzolatların antifungal duyarlılıkları flukonazol, vorikonazol, kaspofungin, mikafungin, amfoterisin B ve flusitozin antifungallerini içeren disposable VITEK 2 AST YS02 test kartları kullanılarak belirlendi. Bulgular: Çeşitli klinik örneklerden toplam 42 Candida türü izole edildi. C. albicans % 66,7 ile en sık soyutlanan tür olurken, non-albicans türler %33,3 oranında saptandı. C.albicans’ı sırasıyla C.glabrata (%11,9), C.kefyr (%7,1), C.tropicalis (%4,8), C.famata (%2,4), C.krusei (%2,4), C.lusitaniae (%2,4) ve C.spherica (%2,4) izledi.Tüm izolatların antifungal direnç oranları sırasıyla; flukonazol %14, flusitozin %3, vorikonazol %6, amfoterisin-B %5, kaspofungin %6, mikafungin %3 oranları belirlendi. C.albicans izolatlarında flukonazol direnç oranı %11 olarak saptandı. C.kefyr, C.lusitaniae ve C.tropicalis izolatlarında mevcut antifungallere direnç görülmedi. C.glabrata’nın antifungal direnç oranı diğer Candida türlerine göre daha yüksekti. Sonuçlar: Çalışmamızda en sık izole edilen C.albican’tan sonra gelen C.glabrata izolatlarının diğer Candida türlerine göre antifungal direncinin daha yüksek olduğu saptanmıştır. Son yıllarda non-albicans türlerin ve antifungal direnç oranlarının artması sebebiyle Candidaların tür düzeyinde tanımlanması ve antifungal duyarlılık testlerinin yapılmasının gerekliliği düşünülmektedir.
